SH202 ABB Miniature Circuit Breaker MCB High performance bipolar
circuit protection safe reliable
Product Overview
ABB SH202 is a 2-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 mature thermomagnetic
tripping technology, featuring high breaking capacity, compact
structure and excellent electrical performance. It is widely used
in single-phase circuits (L+N), control power supplies, socket
lines and terminal distribution boxes, providing efficient and
reliable electrical safety guarantees for personnel and equipment.
Key features
✅ high judgment ability
The rated operating short-circuit breaking capacity is as high as
10 kA (230/400 V AC), meeting the requirements of the vast majority
of civil and light industrial application 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
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
✅ compact modular design
The width is only 2 × 18mm = 36mm (2 poles)
Standard 35mm DIN rail mounting, compatible with all mainstream
distribution boxes and control cabinets
✅ 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 highly scalable
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 flexibly installed
