1SDA100346R1

The ABB 1SDA100346R1 is a SACE Tmax XT5N 630 moulded case circuit breaker (MCCB) designed for reliable protection, switching, and isolation in low-voltage electrical distribution systems. It features a three-pole (3P), fixed construction, front terminals, and a TMA thermomagnetic release. The breaker has a 500 A rated current within a 630 A frame, making it suitable for protecting three-phase electrical circuits against overload and short-circuit conditions. The integrated TMA thermomagnetic release provides thermal overload protection and magnetic short-circuit protection.
