ABB SH201 Miniature Circuit Breaker MCB with 10 kA Breaking Capacity Compact 18mm Width and IEC/EN 60898-1 Compliant

SH201 ABB Miniature Circuit Breaker MCB A reliable choice unipolar circuit protection

Product Overview

ABB SH201 is a single-pole Miniature Circuit Breaker (MCB) in the ABB S200 series, specifically designed for overload and short-circuit protection in residential, commercial and light industrial power distribution systems. With its compact structure, high reliability and excellent breaking performance, SH201 is widely used in lighting circuits, socket branches, control power supplies and terminal distribution boxes, and is an indispensable basic protection component in modern electrical systems.

Key features

✅ high judgment ability

The rated operating short-circuit breaking capacity is as high as 10 kA (230 V AC), meeting the demands of the vast majority of civil and light industrial scenarios.
✅ thermal and magnetic dual protection mechanism

Thermal trip: The bimetallic strip senses the continuous overload current and acts with a delay to prevent the cable from overheating and aging for a long time
Magnetic trip: The electromagnetic coil responds instantaneously to the short-circuit current (5 to 10 times the rated current), quickly cutting off the faulty circuit
✅ extremely compact, space-saving

The width is only 18mm (1P), meeting the modular power distribution standard
Standard 35mm DIN rail mounting, compatible with all mainstream distribution boxes
✅ certified globally, safe and compliant

Compliant with IEC/EN 60898-1 (for household and similar use) and IEC/EN 60947-2 (for industrial use)
Passed international authoritative certifications such as CE, CCC, TUV, UL Recognized (for some models)
✅ is intuitive to operate and flexible to expand

A clear ON/OFF position indicator window
Supports padlock locking (optional accessories required)
Auxiliary contacts, alarm contacts, shunt trip units and other modules can be added (some functions need to be used in conjunction with multiple poles).
