Why Choose the ABB 1SDA048827R1 Extended Auxiliary Contact Set?
The ABB 1SDA048827R1 is a 15-contact external auxiliary contact set designed for withdrawable ABB SACE Emax E1, E2, E3, E4 and E6 air circuit breakers. Part of the ABB Emax circuit breaker accessory range, it provides additional electrical signalling contacts for monitoring the operating and positional status of compatible withdrawable circuit breakers.
The auxiliary contact assembly provides 15 supplementary contacts and is mounted externally to the circuit breaker. It is intended for applications requiring additional status information to be transmitted to control, indication, supervision or automation circuits beyond the auxiliary signalling available in the standard breaker configuration.
For withdrawable Emax installations, the 1SDA048827R1 supports electrical signalling associated with the breaker operating position and isolated/test conditions. Its dedicated ABB design provides compatibility across the SACE Emax E1–E6 range, making it suitable for industrial switchboards and power distribution systems requiring extensive remote status indication.

Extended Signalling for Withdrawable Emax Circuit Breakers
Auxiliary contacts allow the mechanical state of an air circuit breaker to be represented electrically within control and monitoring systems. This enables PLCs, annunciators, supervisory systems and switchboard control circuits to receive status information without relying on direct visual inspection of the breaker.
The ABB 1SDA048827R1 expands this capability with 15 external auxiliary contacts for withdrawable Emax breakers. The additional contacts are particularly useful in complex switchgear installations where multiple independent circuits require breaker operating or positional status signals.
Typical Applications
- ABB SACE Emax withdrawable air circuit breaker installations.
- Low-voltage power distribution switchboards.
- Breaker open/closed and position signalling circuits.
- PLC and industrial automation monitoring systems.
- Remote switchgear status indication.
- Industrial power management and supervisory systems.
