ABB SPCJ4D34-AA Motor Protection Relay Module SPAM 150 C

The ABBSPCJ4D34-AAserves as the core protection module in the ABB SPAM 150 C relay assembly (together with input/output and power supply modules). It continuously monitors phase currents and neutral current, applying multiple protection functions with flexible settings. The module supports both circuit breaker and contactor-controlled motor drives and is suitable for demanding industrial environments, including hazardous areas (ExE motors). It features self-supervision, event recording, and SPA-bus communication for integration into ABB systems.

• Multifunction Protection: Thermal overload, high-set/low-set overcurrent, earth-fault, phase unbalance, incorrect phase sequence, undercurrent, and start-up supervision.

• Thermal Replica: Accurate modeling of motor heating with adjustable parameters and hot/cold memory.

• Start-up Supervision: I²t-based monitoring with optional speed switch input for Ex motors.

• Flexible Settings: Wide setting ranges via front panel switches or communication.

• Self-Supervision: Continuous hardware/software monitoring with IRF (Internal Relay Fault) indication.

• Communication: SPA-bus interface for remote monitoring and parameterization.

• Robust Design: High immunity to disturbances; suitable for 50/60 Hz systems.
