ABB SPER 1C1 RS 485 002-AA SPER 1C1-AAJ RELAY..
The ABB SPER 1C1-AAJ is a specific model number for an ABB Trip Circuit Supervision Relay. This device is used in power electrical installations to continuously monitor critical control circuits, such as those for circuit breakers and disconnectors, ensuring their readiness and detecting faults.
Key features and specifications of the SPER 1C1-AAJ include:
- Function: It provides continuous monitoring of the trip circuit to detect issues like circuit interruptions, bad contacts, contact welding, and auxiliary voltage failures.
- Application: Primarily used to ensure the health of circuit breaker trip circuits, raising an alarm if a fault is detected.
- Voltage Range: The relay supply voltage range is wide, typically 40–265 V DC.
- Communication: The part number SPER 1C1 RS 485 002-AA indicates that this version is equipped with an RS 485 communication interface.
- Design: It is mechanically designed to be compatible with ABB's modular COMBIFLEX system.
- Indication: Features an LED indicator on the front panel and an output relay to signal relay operation or fault conditions.
- Time Delay: Has a preset operate time (e.g., 3 seconds) to prevent nuisance alarms during the brief moment of a circuit breaker's normal operation
