1SDA100067R1

ABB 1SDA100067R1 is a high-performance Tmax XT2H 160 molded case circuit breaker (MCCB) designed for reliable protection, switching, and control of low-voltage electrical distribution systems. The unit is a 3-pole, fixed-type circuit breaker rated at 63 A, equipped with an Ekip Dip LSIG electronic trip unit for comprehensive protection against overload, short circuit, and earth-fault conditions. The LSIG protection configuration provides long-time (L), short-time (S), instantaneous (I), and ground-fault (G) protection, allowing the breaker to be configured to suit a wide range of industrial and commercial power-distribution applications. The XT2H frame offers high short-circuit performance, with a breaking capacity of up to 70 kA at 380–415 V AC, making the device suitable for installations where high fault levels may be present.
