1SDA073767R1 ABB AUP 5 Supplementary Position Contacts 24V DC DX E2.2…E6.2

Why Choose the ABB 1SDA073767R1 Emax 2 Position Auxiliary Contact?

The ABB 1SDA073767R1 is a five-contact supplementary auxiliary position contact assembly designed for withdrawable ABB SACE Emax 2 air circuit breakers. Identified by ABB as AUP 5 suppl.cont. 24Vdc DX E2.2...E6.2, it provides additional electrical position indication for E2.2, E4.2 and E6.2 circuit breaker installations.

As part of the ABB SACE Emax 2 accessory range, AUP auxiliary position contacts are used with withdrawable circuit breakers to signal their connected, test and disconnected positions. The contacts are potential-free and change state as the circuit breaker moves between positions, allowing breaker position information to be incorporated into switchboard monitoring, interlocking and automation systems.

This version provides five changeover auxiliary contacts for 24 V DC signalling applications and is the supplementary right-hand (DX) contact set. It is installed on the fixed part of compatible Emax 2 E2.2, E4.2 and E6.2 withdrawable circuit breaker assemblies.

Reliable Position Signalling for Withdrawable Emax 2 Circuit Breakers

AUP auxiliary position contacts provide electrical indication of the physical position of a withdrawable circuit breaker within its fixed part. The contacts change state as the breaker moves between connected, test and disconnected positions, enabling external control and monitoring equipment to determine its position without relying on visual inspection.

The ABB 1SDA073767R1 adds five supplementary 24 V DC position contacts on the right-hand side of compatible Emax 2 assemblies. This additional signalling capacity is particularly useful in automated switchboards where PLCs, supervisory systems, interlocking circuits or remote monitoring equipment require multiple independent breaker-position signals.

Typical Applications

• ABB SACE Emax 2 E2.2, E4.2 and E6.2 withdrawable air circuit breaker installations.
• Connected, test and disconnected circuit breaker position indication.
• Low-voltage switchboards and switchgear assemblies.
• Remote circuit breaker position monitoring.
• PLC and industrial automation signalling circuits.
• Interlocking and supervisory control systems.
