Why Choose the ABB 1SDA073846R1 AUX15Q Auxiliary Contact Set?
The ABB 1SDA073846R1 is an AUX15Q 400 V AC supplementary auxiliary contact set 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 additional electrical status signalling for applications requiring comprehensive circuit breaker monitoring within low-voltage switchboards.
The accessory provides 15 change-over (CO/SPDT) auxiliary contacts and is intended for withdrawable Emax 2 circuit breakers requiring signalling in the racked-in and test/isolated positions. This allows breaker status information to be incorporated into control, indication, interlocking and supervisory systems.
Designed for ABB Emax 2 E2.2, E4.2 and E6.2 circuit breakers, the 1SDA073846R1 is a loose or configurable accessory manufactured for integration with the Emax 2 platform. The 400 V AC contact version is suited to conventional auxiliary signalling circuits where dependable remote indication of breaker status is required.

Comprehensive Racked-In and Test/Isolated Status Signalling
Auxiliary contacts allow the mechanical state of a circuit breaker to be represented electrically within a control or monitoring system. The ABB 1SDA073846R1 provides 15 change-over contacts, giving system designers multiple independent signalling paths for remote indication, control logic, alarms, interlocking and building or industrial automation interfaces.
This version is specifically intended for withdrawable Emax 2 E2.2–E6.2 circuit breakers with signalling in the racked-in and test/isolated positions. ABB specifies that AUX15Q accessories in this group are not compatible with mechanical locks on compartment doors or mechanical interlocks, so the complete switchboard accessory configuration should be checked when selecting the contact assembly.
Typical Applications
- ABB Emax 2 E2.2, E4.2 and E6.2 withdrawable air circuit breakers.
- Racked-in and test/isolated breaker position signalling.
- Low-voltage switchboard status indication.
- Remote circuit breaker monitoring and alarm systems.
- Control and electrical interlocking circuits.
- Industrial automation, supervisory and power management systems.
