The ABB EB144047SPER 1C1-AA Relay is a trip circuit supervision relay used in electrical power systems to 

continuously monitor critical control and protection circuits, such as circuit‑breaker trip circuits, disconnector 

control circuits, and signalling circuits. This EB144047SPER 1C1-AA relay enhances system safety by identifying 

abnormal conditions including open circuits, bad or welded contacts, and loss of auxiliary DC voltage, and by 

providing immediate indication via an output contact and LED indicator.

Product Applications
Substation : Monitors the trip circuits of high-voltage circuit breakers to ensure that they can reliably receive and 

execute trip instructions in the event of system faults.
Power Plant Control System: Used to protect important generator control circuits and signal circuits, preventing 

protection failure due to control circuit disconnections or auxiliary power supply failures.
Industrial Distribution Network: Conducts real-time monitoring of the control circuits of disconnectors in distribution

systems of heavy industries such as steel and petrochemicals.
Signal and Alarm System: Monitors critical signal transmission links. Once a circuit interruption or anomaly is detected, 

it immediately issues a warning through alarm nodes.

Core functions and technical features
Fault detection: Capable of detecting poor contact, contact adhesion, and auxiliary voltage faults in the monitoring 

circuit.
Delay anti-fault alarm: Features a preset action delay time (typically 3 seconds) to prevent false alarms during the 

normal operation of the circuit breaker.
Wide voltage support: The auxiliary power supply range is usually 40–265 V DC, suitable for various power operation 

power environments.
Visual indication: The front panel is equipped with LED indicators, providing an intuitive display of the relay's operating 

status.
