Product Description
The ABB SPER1C1 is a trip circuit supervision relay designed to monitor critical control circuits in medium‑voltage and high‑voltage electrical installations. It ensures reliable supervision of circuit breaker trip circuits, disconnector control circuits, and signalling circuits, preventing unexpected alarms and operational failures.
This relay continuously monitors circuit integrity, detecting faults such as bad contacts, contact welding, or auxiliary voltage failures. Moreover, a preset operate time prevents false alarms during circuit breaker operation. Designed for COMBIFLEX system mounting, the SPER1C1 integrates seamlessly into ABB’s modular protection and control systems.
