ABB 1SDA073762R1 AUP 6 contacts 400Vac E1.2-XT7-XT7M

This ABB 1SDA073762R1 AUP device is an air circuit breaker configured with 6 contacts and specified for 400Vac operation, fitted with the exact trip unit designation E1.2-XT7-XT7M. As an industrial air circuit breaker and ACB circuit breaker component, it is intended to interrupt and make circuits within low-voltage distribution assemblies where coordinated protection and switching of multiple conductors is required.

Used as part of low-voltage switchgear and distribution assemblies, this ABB air circuit breaker unit is suitable where a compact multi-contact switching and protection element is needed. The unit’s trip unit designation (E1.2-XT7-XT7M) defines its protective and coordination behavior as supplied, making it a specified protection module for installations designed around that trip configuration. Installers and system integrators select this low voltage air circuit breaker when a documented, factory-specified trip unit and multi-contact arrangement are required for system protection and coordination.
