Why Choose the ABB S801S-D20 High Performance MCB?
The ABB S801S-D20 is a high-performance miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection where high breaking capacity is required. As part of the ABB S800S high-performance circuit breaker series, it combines compact modular construction with strong current-limiting performance for commercial and industrial electrical distribution systems.
This circuit breaker features a Type D tripping characteristic, making it particularly suitable for circuits supplying equipment with comparatively high starting or inrush currents. It incorporates a thermal tripping mechanism for overload protection and an electromechanical tripping mechanism for short-circuit protection, while fast arc extinction helps limit fault energy and protect the installation.
With a rated current of 20 A, a 1-pole configuration and a maximum ultimate short-circuit breaking capacity of 50 kA at 240/415 V AC, the S801S-D20 is engineered for demanding protection applications. It can be used at voltages up to 400/690 V AC and is also suitable for DC applications, providing a versatile protection solution within ABB's S800 platform.

Reliable High-Performance Circuit Protection
Miniature circuit breakers such as the ABB S801S-D20 automatically disconnect an electrical circuit when excessive current occurs. Its thermal tripping mechanism responds to sustained overload conditions, while its electromechanical tripping mechanism provides rapid short-circuit protection, helping safeguard conductors, connected equipment and electrical distribution systems.
The S800S series is engineered for installations where high prospective fault currents demand enhanced interruption capability. The S801S-D20 combines high current limitation with a Type D tripping characteristic, making it particularly useful for circuits supplying equipment that can produce substantial transient currents during energisation or starting.
Typical Applications
- Industrial electrical distribution systems.
- Machine and automation control panels.
- Circuits supplying equipment with high starting currents.
- Commercial electrical distribution boards.
- Industrial machinery and production equipment.
- Installations with high prospective short-circuit currents.
