Why Choose the ABB S802S-D20 High Performance MCB?
The ABB S802S-D20 is a high-performance 2-pole miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection in demanding electrical installations. Part of the ABB S800S high-performance circuit breaker range, this model combines a rated current of 20 A with a Type D tripping characteristic for circuits where higher starting or inrush currents may occur.
The S802S-D20 uses separate thermal and electromagnetic tripping mechanisms to protect circuits against overloads and short circuits. Its current-limiting design and rapid arc extinction technology provide a maximum ultimate short-circuit breaking capacity of 50 kA at 240/415 V AC, making it suitable for installations where high prospective fault currents demand greater protection performance than conventional miniature circuit breakers.
With two protected poles, cage terminals and support for AC and DC applications, the S802S-D20 is suited to commercial and industrial distribution systems, machinery and control panels. It complies with IEC/EN 60898-1 and IEC/EN 60947-2, while the S800 modular format supports straightforward DIN-rail installation and integration with compatible ABB accessories.

Reliable High-Performance Circuit Protection
The ABB S802S-D20 combines thermal overload protection with electromagnetic short-circuit protection. During a sustained overload, the thermal mechanism trips the breaker to protect conductors and connected equipment, while the electromagnetic mechanism provides rapid operation when a severe short-circuit current occurs.
Its Type D characteristic is particularly useful for circuits supplying equipment that can produce significant transient starting currents. Together with the S800S range's high current-limiting capability and rapid arc extinction, this makes the S802S-D20 a practical protection solution for demanding commercial and industrial electrical distribution systems.
Typical Applications
- Industrial electrical distribution boards.
- Machinery and automation control panels.
- Circuits with high starting or inrush currents.
- Commercial electrical distribution systems.
- Industrial power distribution installations.
- AC and DC circuit protection applications within the specified ratings.
