Why Choose the ABB AUX 15Q 400V E2.2...E6.2 Auxiliary Contact Set?
The ABB AUX 15Q 400V E2.2...E6.2, order code 1SDA073760R1, is a 15-contact auxiliary signalling set for compatible ABB SACE Emax 2 air circuit breakers. Designed for E2.2, E4.2 and E6.2 frame sizes, it provides electrical open/closed status signalling for integration with switchboard control, indication and automation systems.
The accessory is rated for applications up to 400 V and is intended for fixed or withdrawable Emax 2 circuit breakers, with connected or racked-in position signalling for the applicable withdrawable configuration. The multiple auxiliary contacts allow circuit-breaker state information to be distributed to several control, monitoring and interlocking circuits.
With 15 auxiliary contacts available, the 1SDA073760R1 is particularly suited to sophisticated switchboards requiring extensive breaker-status feedback. It provides an ABB-engineered signalling solution for industrial power distribution, building infrastructure and automated low-voltage switchgear.

Comprehensive Circuit Breaker Status Signalling
Auxiliary contacts allow the mechanical state of a circuit breaker to be represented electrically within external control and supervision circuits. Open and closed status information can therefore be used by indicator lamps, PLC inputs, building management systems, protection schemes and other automation equipment.
With its 15-contact configuration, the ABB 1SDA073760R1 provides extensive signalling capacity for complex Emax 2 installations. Its suitability for fixed and withdrawable E2.2 to E6.2 circuit breakers makes it particularly useful in advanced low-voltage switchboards where several independent systems require breaker-status information.
Typical Applications
- ABB SACE Emax 2 E2.2, E4.2 and E6.2 air circuit breakers.
- Open/closed circuit-breaker status indication.
- Industrial low-voltage distribution switchboards.
- PLC and automation system status inputs.
- Remote switchgear monitoring and supervision.
- Fixed and withdrawable power circuit-breaker installations.
