ABB 1SDA073677R1 YO E1.2..E6.2-XT7-XT7M 380-400 VAC

The ABB 1SDA073677R1 is an air circuit breaker configured with the E1.2..E6.2-XT7-XT7M trip designation and a rated operational voltage of 380–400 VAC. This ACB circuit breaker is designed as a low voltage air circuit breaker for use where reliable overcurrent protection and selective tripping are required. As an ABB air circuit breaker, it is supplied in the manufacturer’s product format and naming convention shown on the unit label.

This industrial air circuit breaker is intended for integration into low-voltage power distribution systems and switchgear assemblies. In those environments it functions to interrupt fault currents and provide overload protection while allowing coordination with downstream protective devices. Users selecting this ACB circuit breaker typically do so to match the specified trip characteristics (E1.2..E6.2-XT7-XT7M) and the 380–400 VAC system voltage for consistent protection performance.
