2CDS211001R0255 ABB SH201-B25 Miniature Circuit Breaker 25 A 1P Type B 6 kA

Why Choose the ABB SH201-B25 Miniature Circuit Breaker?

The ABB SH201-B25 is a compact and reliable single-pole miniature circuit breaker (MCB) designed to protect residential and similar electrical circuits against overloads and short circuits. As part of the ABB Compact Home SH200 series, it combines thermal overload protection with electromagnetic short-circuit protection in a space-saving modular device.

This MCB features a Type B tripping characteristic, making it suitable for circuits with relatively low inrush currents, including resistive loads and general-purpose final circuits. Its current-limiting operation helps interrupt fault currents rapidly, while the modular format enables straightforward integration into consumer units and distribution boards.

With a rated current of 25 A, a rated operational voltage of 230 V AC and a rated short-circuit capacity of 6 kA, the SH201-B25 provides dependable protection for residential and similar electrical installations. The SH200 range is designed in accordance with IEC/EN 60898-1.

Reliable Protection for Residential Electrical Circuits

Miniature circuit breakers such as the ABB SH201-B25 automatically disconnect a circuit when excessive current occurs. A thermal mechanism responds to sustained overload conditions, while an electromagnetic mechanism operates rapidly during short circuits, helping protect wiring and connected equipment against damaging fault currents.

The Type B characteristic is intended for circuits with relatively low starting currents and provides sensitive instantaneous fault protection. The compact SH200 design allows the SH201-B25 to be installed alongside other modular protection and switching devices in residential and similar distribution systems.

Typical Applications

• Residential electrical distribution circuits.
• Domestic consumer units and distribution boards.
• General-purpose final circuits.
• Resistive electrical loads with relatively low inrush current.
• Small commercial electrical installations.
• Suitable 25 A branch and distribution circuits.
