1SDA100347R1

The ABB 1SDA100347R1 is a SACE Tmax XT5N 630 moulded case circuit breaker (MCCB) designed for reliable protection, switching, and isolation of low-voltage electrical distribution systems. It is a three-pole, fixed-type circuit breaker with front terminals and a TMA thermomagnetic release. The breaker has a 630 A rated current, making it suitable for high-current three-phase power-distribution applications. The integrated TMA thermomagnetic release provides thermal protection against overload conditions and magnetic protection against short-circuit faults.
