1SDA067421R1

The ABB 1SDA067421R1 is a SACE Tmax XT1N 160 moulded case circuit breaker (MCCB) designed to provide reliable protection, isolation, and switching in low-voltage electrical distribution systems. It features a four-pole (4P), fixed-mount configuration, front-terminal connections, and a TMD thermomagnetic trip unit for protection against overload and short-circuit conditions. This model has a 50 A rated current within the XT1N 160 frame size. Its TMD thermomagnetic release combines thermal protection for sustained overload conditions with magnetic protection for high-current short-circuit faults.
