Why Choose the ABB 1SDA100407R1 XT5N 400 Circuit Breaker?
The ABB 1SDA100407R1 is a high-performance four-pole moulded case circuit breaker (MCCB) designed for generator protection and low-voltage electrical distribution applications. Part of the advanced ABB SACE Tmax XT series, this XT5N 400 breaker combines a compact fixed design with a TMG thermomagnetic trip unit for dependable overload and short-circuit protection.
This circuit breaker provides a 400 A rated current and 400 A rated uninterrupted current. Its TMG 400-2000 thermomagnetic release provides adjustable overload protection together with instantaneous short-circuit protection adjustable from 1000–2000 A. The four-pole configuration incorporates a fully rated neutral, making it suitable for three-phase four-wire electrical systems where the neutral requires the same current-carrying capability as the phase conductors.
With a rated operational voltage of up to 690 V AC and an ultimate short-circuit breaking capacity of 36 kA at 380–440 V AC, the 1SDA100407R1 provides robust circuit protection for demanding industrial installations. Its fixed construction and front terminal connections enable straightforward integration into generator switchboards, industrial distribution panels and electrical control assemblies.
