CA5-10

The ABB CA5‑10 is a single‑pole auxiliary contact block designed to be front‑mounted on compatible ABB contactors and control relays. It is used to provide additional electrical contacts that mirror the state of the main contactor, enabling enhanced control and feedback functions in industrial automation and motor control applications.

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.
