Schneider Electric LC1D95M7C AC Contactor

Product Details

LC1D95M7C Product Description

The Schneider Electric LC1D95M7C is a 95A three-pole AC contactor from the TeSys D series, engineered for seamless Contextual Integration within layered industrial control architectures. Rated for AC-3 duty at 45 kW / 400 V, with a 220 VAC (M7) coil voltage, this contactor is purpose-built for motor switching, reversing starter assemblies, star-delta transitions, and capacitor bank control across demanding industrial environments. Its compact DIN-rail and panel-mount footprint, combined with full compatibility with the TeSys D auxiliary contact blocks, timer modules, and mechanical interlocks, makes it a cornerstone component in any well-engineered motor control centre (MCC) or control cabinet.

In modern smart factory deployments, the LC1D95M7C does not operate in isolation. It functions as the execution-layer switching element within a coordinated automation stack that spans from the PLC control layer down through I/O modules, communication gateways, power distribution, and field instrumentation. Its coil interface accepts discrete output signals from Schneider Electric Modicon M340 or M580 CPU modules via TM3 or TM2 digital output expansion modules, enabling deterministic, scan-cycle-aligned switching commands. This tight integration between the control layer and the execution layer is what defines a truly system-matched architecture — and the LC1D95M7C is rated and tested to deliver exactly that.

Every unit supplied by NANKMOS undergoes pre-shipment functional verification and ships with a 12-Month Warranty covering coil integrity, contact resistance, mechanical endurance, and auxiliary block compatibility. In-stock availability ensures short lead times for MRO replenishment, project commissioning, and emergency replacement scenarios.

The LC1D95M7C achieves its full performance potential when deployed as part of a coherent, multi-layer automation platform. At the control layer, a Schneider Electric Modicon M580 CPU (BMEP582040) or Modicon M340 CPU (BMXP342020) issues discrete switching commands via Ethernet/IP or Modbus TCP to remote I/O racks. These racks, populated with TM3DQ16R digital output modules or BMXDDO1602 discrete output modules, provide the 220 VAC coil drive signal to the LC1D95M7C with millisecond-level determinism.

For reversing starter configurations — common in conveyor, pump, and fan applications — two LC1D95M7C contactors are paired with a LA9D09 mechanical interlock kit, preventing simultaneous energisation and protecting both the motor and the upstream power distribution system. In star-delta starter assemblies, the LC1D95M7C serves as the main contactor, working in timed coordination with LC1D40 (star) and LC1D40 (delta) contactors, sequenced by a RE22R2QGMR star-delta timer relay mounted on the same DIN rail section.

At the power layer, upstream protection is provided by a GV3P80 manual motor starter or LRD340 overload relay (adjustable 23–32 A range for downstream branch circuits), ensuring coordinated protection across the full motor control chain. For applications requiring power quality monitoring, a PM5350 power meter installed at the MCC incomer provides real-time current, voltage, and energy data accessible via Modbus TCP, enabling predictive maintenance workflows that correlate contactor switching cycles with load trends.

At the communication layer, a BMXNOE0110 Ethernet communication module or TM3BCSL CANopen bus coupler bridges the PLC backplane to the field network, ensuring that contactor status feedback — delivered via LA1DN11 auxiliary contact blocks wired to digital input modules — is available to the SCADA layer in real time. This closed-loop status reporting is essential for alarm management, maintenance scheduling, and regulatory compliance in process industries.

For HMI integration, a Magelis HMIGTO5310 touchscreen panel or HMISCU6A5 compact HMI controller provides operators with contactor run/stop status, trip history, and manual override capability — all without requiring additional field wiring beyond the existing PLC I/O infrastructure. This architecture supports both local panel operation and remote SCADA supervision simultaneously, a critical requirement in unmanned substations and remote pump stations.

Manufacturing & Assembly Lines: In automotive body-in-white welding lines and general assembly conveyors, the LC1D95M7C controls 45 kW drive motors for roller conveyors, transfer units, and indexing tables. Its high mechanical endurance (10 million operations) supports the high-cycle-rate demands of continuous production without scheduled contactor replacement during planned maintenance windows.

Power Distribution & Electrical Substations: In medium-voltage transformer secondary switchboards, the LC1D95M7C is deployed in capacitor bank switching applications (AC-6b duty with appropriate derating), improving power factor correction response time and reducing reactive energy penalties. Its coil supervision via auxiliary contacts enables remote trip confirmation at the SCADA level.

Petrochemical & Refinery Process Control: In hazardous area motor control centres (Zone 2 classified, with the contactor housed in Ex e enclosures), the LC1D95M7C drives cooling tower fans, process pumps, and compressor auxiliaries. The IEC 60947-4-1 compliance and CE marking satisfy the documentation requirements for ATEX-adjacent installations where the contactor itself is located outside the hazardous zone.

Water & Wastewater Treatment: Pump station MCCs controlling submersible pumps, aeration blowers, and UV disinfection systems rely on the LC1D95M7C for reliable motor switching across variable daily duty cycles. Integration with ATV320 variable speed drives in bypass-contactor configurations allows seamless switchover between VFD-controlled and direct-on-line operation during drive maintenance.

Mining & Mineral Processing: Conveyor belt drives, crusher auxiliaries, and slurry pump motors in underground and open-cut mining operations demand contactors with high short-circuit withstand ratings and robust mechanical construction. The LC1D95M7C, coordinated with GV7RS80 motor circuit breakers, provides the required fault current interruption capability and selective coordination within the mine's power distribution hierarchy.

Packaging & Material Handling: High-speed palletisers, stretch wrappers, and sortation systems require contactors capable of frequent start-stop cycles with minimal coil heating. The LC1D95M7C's low sealed power consumption and compatibility with LAD4RCU RC surge suppressor modules minimises coil voltage transients, extending both contactor and PLC output module service life in electrically noisy panel environments.

Q1: Is the LC1D95M7C compatible with Schneider Electric TeSys D overload relays for a complete motor starter assembly? Yes. The LC1D95M7C is fully compatible with the LRD3359 overload relay (80–104 A range) for direct mounting without additional adapters, forming a complete IEC-compliant motor starter assembly. The combined unit can be mounted on a DIN rail or directly onto a GV3 manual motor starter for a compact, three-device motor protection chain. This assembly satisfies IEC 60947-4-1 Type 2 coordination requirements when paired with the appropriate upstream fuse or circuit breaker, a critical compliance point for industrial insurance and regulatory audits.

Q2: How does the LC1D95M7C integrate into a Modicon PLC architecture for remote start-stop control and status feedback? The LC1D95M7C coil (220 VAC, M7) is driven directly from a TM3DQ16R or BMXDDO1602 discrete output module rated for 240 VAC outputs. The PLC program issues a SET/RESET coil instruction on the corresponding output channel, and the contactor's LA1DN11 auxiliary contact block (1 NO + 1 NC) wires back to a digital input module (e.g., TM3DI16 or BMXDDI1602) to confirm energised/de-energised state. This feedback loop enables the PLC to detect welded contacts, coil failures, or mechanical jams within one scan cycle, triggering alarms in the SCADA system and preventing cascading faults in the process line. No additional communication hardware is required beyond the standard PLC I/O infrastructure.

Q3: What does the 12-Month Warranty cover, and what is NANKMOS's stock and lead time commitment for the LC1D95M7C?
