Why Choose the ABB SH204-D32 Miniature Circuit Breaker?

The ABB SH204-D32 is a robust 4-pole miniature circuit breaker (MCB) designed to provide overload and short-circuit protection in electrical installations. As part of the ABB SH200 MCB range, it combines a 32 A rated current, Type D tripping characteristic and 6 kA short-circuit breaking capacity in a compact DIN rail-mounted format.

The SH204-D32 provides dependable circuit protection using thermal and electromagnetic tripping mechanisms. The thermal mechanism responds to sustained overload conditions, while electromagnetic operation provides rapid interruption during short circuits. Its Type D characteristic is designed for circuits with higher inrush currents, making it particularly suitable for appropriate inductive and high-starting-current loads.

With a rated current of 32 A, a 6 kA short-circuit breaking capacity and a 4-pole configuration, the SH204-D32 provides coordinated multipole protection for electrical distribution circuits. Its modular construction and DIN rail mounting enable straightforward integration into electrical distribution boards and control panels.

Reliable Protection for Higher-Inrush Circuits

Miniature circuit breakers such as the ABB SH204-D32 automatically interrupt electrical circuits when overload or short-circuit conditions occur. Thermal tripping provides protection against sustained overloads, while electromagnetic tripping responds rapidly to severe short-circuit currents, helping protect electrical wiring and connected equipment against damaging overcurrent conditions.

The Type D characteristic accommodates higher transient starting currents than Type B or Type C characteristics, making it suitable for appropriately designed circuits supplying equipment that can produce significant inrush current during start-up. Combined with its four-pole construction and 32 A current rating, the SH204-D32 provides a practical protection solution for demanding multipole electrical circuits.
