Why Choose the ABB 1SDA050151R1 15 Extended Auxiliary Contacts?
The ABB 1SDA050151R1 is a 15-contact external auxiliary contact accessory designed for withdrawable ABB SACE Emax air circuit breakers. Identified by ABB as 15 EXT.AUX.CON. X WITHDRAWABL V<24V, it provides additional electrical signalling contacts for applications using control voltages below 24 V.
Auxiliary contacts allow circuit breaker status to be communicated electrically to external control, indication and monitoring equipment. With 15 extended auxiliary contacts, the 1SDA050151R1 provides substantial additional signalling capacity for switchboards requiring multiple status inputs for PLCs, annunciators, interlocking circuits, supervisory systems and other compatible control equipment.
As part of the ABB SACE Emax / New Emax accessory range, the 1SDA050151R1 is specifically intended for withdrawable circuit breaker configurations. Its below-24 V design makes it particularly suitable for low-level digital signalling in automated industrial and commercial power distribution systems.

Extended Low-Voltage Signalling for Withdrawable Emax Breakers
Withdrawable air circuit breakers are frequently integrated into sophisticated switchgear control systems where several independent circuits require electrical information about breaker status. Extended auxiliary contacts increase the number of available signalling points without requiring separate external sensing devices.
The ABB 1SDA050151R1 provides 15 additional contacts for signalling below 24 V, making it well suited to digital control environments. The contacts can support multiple monitoring, indication and automation functions in installations where comprehensive breaker-state information is required.
Typical Applications
- ABB SACE Emax withdrawable air circuit breaker installations.
- Low-voltage power distribution switchboards.
- Circuit breaker status signalling circuits.
- PLC and industrial automation inputs.
- Remote indication and switchgear annunciation.
- Power management, interlocking and supervisory control systems.
