The ABB 1SDA063550R1 is a Molded Case Circuit Breaker (MCCB) from the T7M series, designed for load center applications in industrial and commercial power distribution. It sits within the broader category of circuit breakers, fuses, and protection devices, and is rated for use in panelboards and switchgear where overcurrent protection and selective coordination are required.
