ABB SPER1C1-AAJ Trip Circuit Supervision Relay Brand New

SPER 1C1-AAJ – Trip Circuit Supervision Relay

Overview

The SPER 1C1-AAJ supervision relay continuously monitors circuit-breaker trip circuits and other essential control circuits in power electrical installations. It is primarily used to supervise critical control and signaling circuits such as those for circuit-breakers and disconnectors. Typically, one relay is required per circuit to be supervised. For circuits with multiple branches, multiple relays can be connected to the same control circuit.

The SPER 1C1-AAJ relay is mechanically designed for integration with the COMBIFLEX system and operates within a wide supply voltage range of 40–265 V DC.

For rail-mounted or surface-mounted versions, see the SPER 1B1 C4 model.

Scope

• Relay for man or backup circuit supervision

Product Benefits

• Provides immediate fault indication to enable prompt response

Key Features

• Continuous monitoring of circuit-breaker trip circuits and other vital control circuits

• Preset operate time to prevent false alarms during circuit-breaker operation

• Relay operation indicated by an LED on the front panel and by the output relay

• Detects faults such as bad contacts, contact welding, and auxiliary voltage failures within the supervised circuit
