Why Choose the ABB 1SDA043475R1 Extended Auxiliary Contact Set?
The ABB 1SDA043475R1 is a genuine 15-contact extended open/closed auxiliary contact set designed for compatible ABB SACE Emax E1–E6 air circuit breakers. Installed externally to the circuit breaker, this accessory expands the number of electrical status contacts available for signalling the breaker's open and closed operating states.
Auxiliary contacts provide electrical feedback that can be used by switchboard indication circuits, PLCs, supervisory systems and electrical interlocks. With 15 supplementary contacts, the 1SDA043475R1 is particularly useful in complex industrial installations where multiple independent circuits require reliable breaker open/closed status information.
This version is intended for fixed ABB SACE Emax E1–E6 circuit breakers. Its external mounting arrangement provides substantial additional signalling capacity without relying solely on the standard auxiliary contacts fitted internally to the breaker.

Expanded Open/Closed Status Signalling for Circuit Breakers
Circuit-breaker auxiliary contacts translate the mechanical open or closed state of the breaker into electrical signals that can be used elsewhere in a control system. These signals are commonly connected to indicator circuits, programmable controllers, building or plant management systems and electrical interlocks.
The ABB 1SDA043475R1 expands this capability with 15 externally mounted auxiliary contacts for compatible fixed SACE Emax breakers. The additional contact capacity makes it particularly suitable for installations where breaker status must be distributed simultaneously to several independent monitoring and control functions.
Typical Applications
- Open/closed status indication for ABB circuit breakers.
- Industrial low-voltage switchboards.
- PLC and automation system inputs.
- Remote circuit-breaker monitoring.
- Electrical interlocking and control circuits.
- SCADA and supervisory power-management systems.
- Fixed ABB SACE Emax E1–E6 circuit-breaker installations.
