ABB 1SDA073700R1 YU E1.2..E6.2-XT7-XT7M 220-240 VAC/DC

ABB 1SDA073700R1 Air Circuit Breaker – 220–240 VAC/DC, Trip unit E1.2..E6.2

This ABB 1SDA073700R1 air circuit breaker is a compact protection and switching device identified by the designation YU E1.2..E6.2-XT7-XT7M and rated for 220–240 VAC/DC control supply. As an industrial air circuit breaker and ACB circuit breaker component, it provides electronic trip functionality via the specified trip unit range, making it suitable where precise adjustable protection and remote trip/control interfaces are required. The product name and ratings indicate it is intended for use as the protective switching element within low voltage air circuit breaker assemblies and control modules.

In low-voltage power distribution, this ABB air circuit breaker is used where an electronic trip unit with adjustable current settings (E1.2..E6.2) and a 220–240 VAC/DC control supply are required. It is selected in switchgear when users need an ACB circuit breaker with the specific trip family and supply compatibility shown in the model code, for tasks such as selective overcurrent protection, circuit isolation, and integration with XT7/XT7M control interfaces. The ABB air circuit breaker designation helps engineers match trip characteristics and control voltage when designing switchgear layouts or retrofitting protection modules.
