Why Choose the ABB 1SDA073847R1 AUX15Q Auxiliary Contact Set?
The ABB 1SDA073847R1 is an AUX15Q supplementary 24 V DC auxiliary contact assembly designed for ABB Emax 2 E2.2 through E6.2 air circuit breakers. Part of the ABB Emax 2 air circuit breaker accessory range, it provides extensive electrical status signalling for withdrawable circuit breakers used in low-voltage switchboards and power distribution systems.
The accessory provides 15 change-over (CO/SPDT) auxiliary contacts and is specifically intended for withdrawable configurations requiring signalling in the racked-in and test/isolated positions. Its 24 V DC contact version is well suited to low-voltage control, indication, PLC, interlocking and supervisory circuits.
Designed for ABB Emax 2 E2.2, E4.2 and E6.2 circuit breakers, the 1SDA073847R1 features spring-clamp electrical connections and side mounting. It provides a dedicated ABB solution for applications requiring multiple independent breaker status signals from a compatible withdrawable Emax 2 installation.

24 V DC Racked-In and Test/Isolated Status Signalling
Auxiliary contacts convert the mechanical status of a circuit breaker into electrical signals that can be used by control and monitoring equipment. With 15 independent change-over contacts, the ABB 1SDA073847R1 provides substantial signalling capacity for applications requiring multiple indications, PLC inputs, alarms, interlocks or connections to supervisory power management systems.
This version is specifically designed for withdrawable Emax 2 E2.2–E6.2 circuit breakers requiring signalling in the racked-in and test/isolated positions. The AUX15Q configuration is not compatible with mechanical locks on compartment doors or mechanical interlocks, so the overall Emax 2 accessory arrangement should be checked when specifying the assembly.
Typical Applications
- ABB Emax 2 E2.2, E4.2 and E6.2 withdrawable air circuit breakers.
- Racked-in and test/isolated circuit breaker position signalling.
- 24 V DC PLC and industrial automation inputs.
- Low-voltage switchboard status indication and alarm circuits.
- Remote circuit breaker monitoring and electrical interlocking.
- Power management and supervisory control systems.
