1SDA100345R1

The ABB 1SDA100345R1 is a SACE Tmax XT5N 400 moulded case circuit breaker (MCCB) designed for reliable protection, switching, and isolation of low-voltage electrical distribution systems. It is a three-pole (3P), fixed-mount circuit breaker equipped with front terminals and a TMA thermomagnetic release. The breaker has a 400 A rated current and is intended to protect three-phase electrical circuits from overload and short-circuit conditions. The integrated TMA thermomagnetic release provides thermal protection against overloads and magnetic protection against short-circuit faults.
