Why Choose the ABB S801N-B20 High Performance MCB?
The ABB S801N-B20 is a high-performance 1-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding electrical distribution systems. As part of the ABB S800N high-performance circuit breaker series, it combines high fault-current interruption capability with a compact modular design for commercial and industrial applications.
This current-limiting circuit breaker features a Type B tripping characteristic and a rated current of 20 A. Its thermal tripping mechanism provides protection against sustained overloads, while the electromagnetic mechanism responds rapidly to short-circuit faults. The Type B characteristic is particularly suitable for circuits with relatively low starting or inrush currents.
With a breaking capacity of 36 kA, the S801N-B20 provides robust protection in installations where substantial prospective fault currents may occur. Its single-pole configuration is suited to individual conductor protection, while the S800N series' current-limiting design supports rapid and dependable fault interruption.

High-Performance Circuit Protection
The ABB S800N range is engineered for installations requiring compact circuit protection combined with high short-circuit interruption capability. Its thermal trip responds to sustained overload conditions, while the electromagnetic trip provides rapid interruption when severe short-circuit currents occur.
The S801N-B20 combines a 20 A current rating with a Type B trip curve, making it well suited to distribution and equipment circuits where significant starting currents are not normally expected. Current-limiting operation helps reduce the energy passed through during a fault, supporting the protection of conductors and downstream electrical equipment.
Typical Applications
- Commercial electrical distribution systems.
- Industrial control and auxiliary circuits.
- Industrial control panels and switchboards.
- Lighting and general-purpose circuits with relatively low inrush currents.
- Automation and production equipment.
- Circuits requiring high short-circuit interruption capability.
