ABB EB144052SPER 1C1‑AA SPER 1C1 Relay is an industrial-grade trip circuit supervision relay designed by ABB for reliable monitoring of essential protection and control circuits in electrical power systems. It continuously supervises critical circuits — such as circuit-breaker trip circuits, disconnector control circuits, and signaling lines — to detect faults (e.g., open/short circuits, contact failures, loss of auxiliary DC supply) and signal them promptly to the protection system, enhancing safety and minimizing downtime in substations and industrial installations.
