ABB 1SDA073764R1 AUP 5 contacts 400Vac SX E2.2...E6.2

The ABB 1SDA073764R1 AUP is an air circuit breaker designed for low-voltage electrical distribution where a multi-contact switching device is required. This specific unit is described as having 5 contacts and a rated operational voltage of 400Vac, and is intended to perform switching and protection duties as part of an electrical distribution assembly. As an ABB air circuit breaker, it fits into installations that call for an ACB circuit breaker with discrete contact configuration.

In low-voltage power distribution, this industrial air circuit breaker is used inside switchgear assemblies and distribution panels to provide a controlled means of opening and closing circuits at 400Vac. The 5-contact arrangement supports applications that require an additional control or earth/neutral contact alongside the main line contacts. Installers and panel builders select an ABB air circuit breaker like this when they need a purpose-built ACB circuit breaker from a recognized manufacturer for coordinated switching and isolation within low voltage switchgear.
