ABB SH204 4-Pole Miniature Circuit Breaker MCB with 10 kA Breaking Capacity and 4P Configuration

SH204 ABB Miniature Circuit Breaker MCB High performance highly secure circuit protection solutions

Product Overview

ABB SH204 is a 4-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. This product adopts a thermal-magnetic tripping mechanism, featuring high breaking capacity, compact structure and outstanding reliability. It is widely used in terminal distribution boxes, control cabinets, building automation systems and OEM equipment, providing comprehensive electrical safety protection for personnel and equipment.

Key features

✅ high judgment ability

The rated operating short-circuit breaking capacity is as high as 10 kA (400 V AC), meeting the demands of most civil and light industrial scenarios.
✅ thermal magnetic double protection

Thermal trip: The bimetallic strip senses overload current and acts with a delay to protect the cable from long-term overheating damage
Magnetic trip: The electromagnetic coil responds instantaneously to the short-circuit current, quickly cutting off the fault and preventing equipment damage
✅ modularized & space-saving

The width is only 4 × 18mm = 72mm (4 poles)
Standard DIN rail mounting (35mm), compatible with all mainstream distribution boxes
✅ security compliance certification

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

A clear ON/OFF indicator window
The handle has a moderate operating force and supports padlock locking (optional accessories are required)
A variety of accessories can be optionally equipped, such as auxiliary contacts, alarm contacts, shunt trip units, etc
