Key Features Accessory Type: Auxiliary contact block for contactors and relays. Pole Count: 1 pole — one auxiliary contact. Contact Configuration: 1 Normally Open (1 NO) contact — closes when the associated contactor energizes. Mounting Style: Front mounted on ABB contactor bodies. Connection: Screw‑type terminals for secure wiring. Expands control circuit capabilities without altering the main power path. Electrical Ratings Rated Operational Voltage: Up to 690 V AC. Rated Control Current (AC‑15): ~6 A at 24–127 V AC Up to ~2 A at 500–690 V AC Rated Frequency: 50 / 60 Hz. Utilization Category: AC‑15/DC‑13 for control circuitry (suitable for PLC inputs, indicator circuits, interlocks). Mechanical & Performance Operating Cycles: Designed for repeated switching — several thousand cycles per hour. Protection: Terminals touch‑protected to IP20 when installed inside an enclosure. Construction: Compact block for front‑mount integration with contactor assemblies. Physical & Installation Installation: Clips or bolts onto the front of an ABB contactor. Housing: Durable polymer body with clearly marked terminals. Terminals: Screw connections for control wiring. Typical Applications Control logic feedback: Signal to PLCs, relays, or indicator lights when the main contactor closes or opens. Interlocking: Electrical interlock schemes between contactors or stages of control. Automation systems: Expands functionality without modifying the main load circuit.
