Why Choose the ABB S802S-B3 High Performance MCB?
The ABB S802S-B3 is a high-performance two-pole miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection in demanding electrical distribution systems. As part of the ABB S800S high-performance MCB series, it combines robust circuit protection with high breaking capacity for industrial and commercial installations.
This circuit breaker features a Type B tripping characteristic, making it suitable for circuits with relatively low inrush currents, including resistive loads, lighting, control circuits and general electrical distribution. Thermal and electromagnetic tripping mechanisms provide protection against sustained overloads and short-circuit faults.
With a rated current of 3 A, a two-pole configuration and a rated ultimate short-circuit breaking capacity of up to 50 kA, the S802S-B3 is engineered for applications requiring reliable multi-pole isolation and high fault interruption performance. Its modular DIN rail format supports straightforward integration into electrical panels and distribution equipment.

High-Performance Circuit Protection
The ABB S800S range is designed to protect electrical circuits and connected equipment against overload and short-circuit conditions where high interruption capability is required. Thermal tripping responds to sustained overload currents, while electromagnetic tripping provides rapid disconnection during short-circuit faults.
The Type B characteristic provides sensitive magnetic tripping for circuits where large starting currents are not normally expected. Combined with the S800S series' high breaking capacity and current-limiting performance, this makes the S802S-B3 suitable for reliable protection in demanding commercial and industrial electrical systems.
Typical Applications
- Industrial electrical distribution systems.
- Machine control panels and automation equipment.
- Control and auxiliary circuits.
- Resistive electrical loads.
- Commercial lighting circuits.
- Distribution boards and electrical panels.
- Circuits with high prospective short-circuit currents.
