Why Choose the ABB 1SDA050145R1 15 Extended Auxiliary Contacts?
The ABB 1SDA050145R1 is a set of 15 extended open/closed auxiliary contacts designed for ABB SACE Emax E1–E6 air circuit breakers. Engineered for low-level electrical signalling at voltages below 24 V, these contacts provide additional breaker status information for control, monitoring and automation systems.
Auxiliary contacts electrically indicate whether the associated circuit breaker is in the open or closed state. The 1SDA050145R1 expands the number of available signalling points to 15, making it particularly useful in switchboards where breaker status must be distributed to multiple PLC inputs, indication circuits, supervisory systems or other low-voltage control equipment.
Designed as part of the ABB SACE Emax / New Emax accessory range, this contact assembly is intended for Emax E1 through E6 breakers and is optimised for low-voltage digital signalling. It provides a manufacturer-designed method of extending breaker status monitoring without relying on separate external sensing devices.

Extended Low-Voltage Signalling for Emax Circuit Breakers
Reliable breaker status information is essential in automated power distribution systems. The ABB 1SDA050145R1 provides multiple electrically independent signalling points that can communicate the open or closed state of a compatible Emax circuit breaker to external control and monitoring equipment.
Its below-24 V signalling capability makes the accessory particularly suitable for low-level digital control circuits. With 15 contacts available, a single breaker can provide status information to multiple control, indication and supervisory functions within sophisticated industrial switchgear installations.
Typical Applications
- ABB SACE Emax E1–E6 air circuit breaker installations.
- Low-voltage power distribution switchboards.
- Breaker open/closed status indication.
- PLC and industrial automation input circuits.
- Remote switchgear monitoring and annunciation.
- Building and industrial power management systems.
