Why Choose the ABB 1SDA073778R1 Emax 2 S51 Trip Signalling Contact?
The ABB 1SDA073778R1 is an S51 trip signalling contact designed for ABB SACE Emax 2 E2.2, E4.2 and E6.2 air circuit breakers equipped with an Ekip protection trip unit. Identified by ABB as S51 250V E2.2...E6.2, this accessory provides electrical indication when the Ekip protection trip unit has caused the associated circuit breaker to trip.
As part of the ABB SACE Emax 2 accessory range, the S51 contact allows protection trip events to be communicated to external signalling, monitoring and automation equipment. This enables operators and supervisory systems to identify a protection-initiated trip remotely and incorporate circuit breaker trip status into wider switchboard control and power management systems.
This 250 V version is designed for Emax 2 E2.2, E4.2 and E6.2 frame sizes. It provides a dedicated signalling interface for Ekip protection trip operation, making it suitable for industrial and commercial switchgear where dependable remote fault and trip indication is required.
