ABB SU200 MCB

ABB's SU200 series of miniature circuit breakers (MCBs) are designed to provide reliable circuit protection for industrial, commercial, and residential power distribution systems. These circuit breakers support AC and DC circuits, cover a current range of 0.2–63A, and offer a variety of trip characteristics (C, K, and Z) to meet the needs of different load types. The SU200 MCBs feature a rugged RAL 7035 flame-retardant thermoplastic enclosure, are DIN rail mountable, and feature clear switch position indicators for safe operation. With a short-circuit breaking capacity of up to 10kA (UL) or 15kA (IEC), they provide effective protection for equipment and circuits and comply with international standards such as UL 489, CSA 22.2, and IEC/EN 60947-2. Whether used for industrial motors, lighting systems, or power distribution lines, the SU200 MCBs provide stable and reliable overload and short-circuit protection.
