Why Choose the ABB 1SDA050153R1 4 Open/Closed Auxiliary Contacts?
The ABB 1SDA050153R1 is a four-contact open/closed auxiliary signalling accessory designed for ABB SACE Emax E1–E6 air circuit breakers. Identified by ABB as 4 OPEN/CLOSED AUX.CONTACTS V<24V E1/6, it provides electrical indication of the circuit breaker's open and closed operating states for compatible control and monitoring systems.
Designed for low-level signalling circuits operating below 24 V, the 1SDA050153R1 is suitable for digital status indication in modern switchgear. Its four auxiliary contacts enable breaker-state information to be incorporated into PLC inputs, remote indication, interlocking logic, annunciation and supervisory control systems.
As part of the ABB SACE Emax / New Emax accessory range, the 1SDA050153R1 is suitable for E1, E2, E3, E4 and E6 circuit breakers. It provides a compact ABB-engineered solution where four open/closed status signals are required without the larger contact count of extended auxiliary contact assemblies.

Low-Voltage Open/Closed Signalling for Emax Switchgear
Reliable knowledge of a circuit breaker's operating state is important in automated power distribution systems. The ABB 1SDA050153R1 provides four electrical signalling contacts that allow compatible external equipment to identify and utilise the open or closed state of an Emax circuit breaker.
The below-24 V signalling specification makes the accessory particularly appropriate for low-level digital interfaces. Its four contacts can support multiple status-dependent functions within a switchboard, including PLC monitoring, remote indication, annunciation and control interlocking.
Typical Applications
- ABB SACE Emax E1–E6 air circuit breaker installations.
- Circuit breaker open/closed status indication.
- Industrial and commercial low-voltage switchboards.
- PLC and automation input circuits.
- Remote indication and switchgear annunciation.
- Interlocking and supervisory control systems.
