Why Choose the ABB 1SDA126342R1 AUP 5 Auxiliary Position Contacts?
The ABB 1SDA126342R1 is an AUP auxiliary position contact set designed for ABB SACE Emax 3 withdrawable air circuit breakers in frame sizes E2.3–E6.3. The accessory provides five contacts for electrically signalling the mechanical position of the withdrawable circuit breaker within its fixed part.
Configured as a left-side contact set, the 1SDA126342R1 uses a 2I1T2E arrangement, providing two contacts for the inserted position, one contact for the test position and two contacts for the extracted position. This enables control and monitoring systems to identify the breaker position and use that information for signalling, automation and interlocking functions.
This version is designed for 24 V DC control and signalling circuits, with ABB specifying a maximum contact load of 0.1 A. Compatible with Emax 3 E2.3, E4.3 and E6.3 withdrawable installations, the 1SDA126342R1 provides dedicated position feedback for demanding low-voltage switchgear applications.

Reliable Position Signalling for Emax 3 Switchgear
Withdrawable air circuit breakers can occupy inserted, test and extracted positions within their fixed parts. Reliable electrical indication of these states is important for switchboard monitoring, remote status indication, automation sequences and interlocking logic. ABB AUP contacts provide dedicated electrical feedback linked to these physical breaker positions.
The 1SDA126342R1 provides five 24 V DC contacts arranged as 2I1T2E, giving two signals associated with the inserted position, one with the test position and two with the extracted position. This left-side contact set is designed for compatible Emax 3 E2.3–E6.3 withdrawable installations and has a maximum contact load of 0.1 A.
Typical Applications
- ABB SACE Emax 3 withdrawable air circuit breaker installations.
- Low-voltage switchboard breaker-position monitoring.
- Inserted, test and extracted position signalling.
- 24 V DC control and signalling circuits.
- Switchgear automation and control systems.
- Remote breaker-position indication.
- Electrical interlocking and control logic.
- Industrial and critical-power switchboards.
