ABB 1SDA073749R1 YR 250 VAC/DC E2.2...E6.2

This ABB 1SDA073749R1 YR device is presented as an air circuit breaker variant specified in the product title with a rated voltage indication of 250 VAC/DC and trip unit designation E2.2...E6.2. It is an industrial air circuit breaker intended for use where an ACB circuit breaker form-factor is required to provide switching and overcurrent protection within low-voltage installations rated at or interfaced to 250 V AC or DC systems.

In low-voltage power distribution, this ABB air circuit breaker is used as a protective switching element that isolates and protects circuits and equipment on 250 VAC/DC distribution rails. As an ACB circuit breaker with the E2.2...E6.2 trip unit designation shown in the title, it is intended to work where that specific trip characteristic is required for coordination and selective protection in switchgear assemblies and control panels.
