Product Details

SSKT160-08 RE400AEPJH1ABB-P Product Description

The ABB SSKT160-08 RE400AEPJH1ABB-P is a precision-engineered SACE series connection module designed to support energy-efficient circuit breaker integration across demanding industrial environments. As a core accessory within ABB's SACE Tmax XT and Formula breaker ecosystem, this module enables reliable signal routing, auxiliary contact expansion, and energy-aware load management — making it an essential component for factories pursuing measurable reductions in operational energy consumption and unplanned downtime.

Sourced directly and held in verified inventory, every unit undergoes pre-shipment functional testing to confirm contact integrity, terminal torque compliance, and signal continuity before dispatch. A 12-month warranty is included as standard, covering manufacturing defects and ensuring your production line remains protected throughout the operational cycle.

In a modern smart production line, energy efficiency is not achieved by a single device — it is the result of coordinated communication between every layer of the control architecture. The ABB SSKT160-08 RE400AEPJH1ABB-P connection module sits at the interface between the circuit breaker and the broader automation system, enabling real-time status feedback that drives intelligent load decisions upstream.

When paired with an ABB AC500 PLC or equivalent programmable logic controller, the auxiliary contact signals from this module can be mapped directly to digital input modules, allowing the controller to monitor breaker state — open, closed, tripped — without additional sensing hardware. This eliminates redundant instrumentation and reduces the I/O overhead on the control cabinet. In energy-intensive applications, the PLC can use this feedback to implement load-shedding sequences, preventing peak demand spikes that inflate energy costs.

On the drive side, integration with ABB ACS880 variable speed drives or ACS580 general-purpose drives becomes more deterministic when breaker status is reliably communicated. A tripped breaker upstream of a drive feeder can trigger an immediate controlled stop sequence rather than an uncontrolled coast-down, protecting both the motor and the mechanical load. This is particularly relevant in conveyor systems, compressor banks, and pump stations where abrupt stops cause mechanical stress and energy waste during restart ramp-up.

For facilities using ABB Ability Energy Manager or third-party SCADA platforms such as Ignition or WinCC, the SSKT160-08 module's contact outputs can feed into ABB CM-EFS energy monitoring relays or ABB B21 / B23 energy meters to correlate breaker switching events with consumption data. This creates a timestamped audit trail of load events — invaluable for identifying phantom loads, optimising shift-based energy profiles, and supporting ISO 50001 energy management reporting.

In motor control centre (MCC) configurations, the module works alongside ABB AF-series contactors and ABB E-series overload relays to form a complete motor protection and energy monitoring chain. The auxiliary contacts provide the interlock signals needed for star-delta starting sequences, reducing inrush current and the associated thermal stress on supply transformers — a direct contributor to lower heat load in the electrical room and extended transformer service life.

Communication-layer integration is equally straightforward. Where ABB PROFIBUS DP or PROFINET communication adapters are deployed on the breaker or drive level, the SSKT160-08 module's status signals can be aggregated into the fieldbus data frame, making breaker health visible to the HMI — such as an ABB CP600 operator panel — without additional wiring runs. Operators gain live visibility of switchgear status, enabling faster fault response and reducing mean time to repair (MTTR).

Factory energy optimisation programmes consistently identify switchgear interface reliability as a hidden source of energy waste. When a connection module fails or delivers intermittent contact signals, the downstream effect is a cascade of unnecessary restarts, false-trip investigations, and manual resets — each consuming technician time and extending the period during which equipment runs in an unoptimised state.

The ABB SSKT160-08 RE400AEPJH1ABB-P addresses this at the source. Its robust contact block construction maintains consistent signal quality across the full thermal and vibration range of an industrial switchgear panel, ensuring that the PLC or SCADA system always receives accurate breaker state data. Accurate data means fewer nuisance alarms, fewer unnecessary interventions, and a production line that maintains its intended cycle time without energy-wasting interruptions.

From a thermal management perspective, a correctly seated and torqued connection module reduces resistive heating at the breaker terminal interface. In high-density MCC panels where multiple breakers are mounted in close proximity, cumulative terminal heating can elevate ambient cabinet temperature, forcing cooling systems to work harder and increasing overall facility energy consumption. Replacing aged or non-OEM connection accessories with verified ABB SACE modules is a low-cost, high-impact step in any panel thermal audit.

Predictive maintenance programmes benefit directly from reliable auxiliary contact data. When integrated with a condition monitoring platform, consistent open/close cycle counts from the SSKT160-08 module allow maintenance teams to schedule breaker servicing based on actual switching history rather than fixed calendar intervals. This shifts maintenance from reactive to predictive, reducing both unplanned downtime and the energy penalty associated with emergency restarts of cold equipment.

For production lines operating across multiple shifts, the module's compatibility with energy management systems enables shift-based load profiling. By correlating breaker switching events with production output data, energy managers can identify which shifts or product runs carry the highest energy intensity per unit produced — and target process improvements accordingly. Over a 12-month operational period, this data-driven approach typically yields measurable reductions in energy cost per unit without capital investment in new machinery.

Every ABB SSKT160-08 RE400AEPJH1ABB-P unit shipped from NANKMOS inventory has been individually tested for contact resistance, mechanical operation, and terminal integrity. This pre-shipment validation ensures that the module performs to ABB SACE specification from the moment it is installed, eliminating the commissioning delays and repeat call-outs that arise from field-discovered defects in untested components.

Q1: What energy efficiency benefit does the SSKT160-08 RE400AEPJH1ABB-P provide in a production line context? The module enables accurate, real-time breaker status feedback to PLCs and SCADA systems, supporting load-shedding logic, predictive maintenance scheduling, and shift-based energy profiling. By eliminating signal ambiguity at the breaker interface, it reduces unnecessary restarts and the associated energy spikes, contributing to a lower energy cost per production unit over time.

Q2: Which ABB SACE breaker models is this connection module compatible with? The SSKT160-08 RE400AEPJH1ABB-P is designed for use within the ABB SACE Tmax XT and Formula series circuit breaker range, rated up to 160 A. If you are unsure whether this module matches your existing breaker frame and pole configuration, please contact us with your breaker nameplate data and we will confirm compatibility before shipment.

Q3: What does the pre-shipment testing process cover, and is a warranty included? Every unit undergoes pre-shipment testing covering contact integrity verification, terminal torque compliance, and signal continuity checks. A 12-month warranty is included as standard, covering manufacturing defects. Units are dispatched from verified stock and are traceable to original ABB supply chain documentation.

Q4: How quickly can this module be supplied, and is it available for urgent replacement orders? The SSKT160-08 RE400AEPJH1ABB-P is held in ready inventory at NANKMOS and is available for immediate dispatch.
