Why Choose the ABB S801S-B8-R High Performance MCB?
The ABB S801S-B8-R is a high-performance single-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding electrical installations. Part of the ABB S800S high-performance circuit breaker range, this model combines an 8 A rated current, Type B tripping characteristic and 50 kA breaking-capacity class.
The S801S-B8-R combines thermal overload protection with rapid electromagnetic short-circuit tripping. Its Type B characteristic provides sensitive magnetic fault protection for circuits with relatively low normal inrush currents, while the current-limiting design helps reduce the electrical and thermal energy passed through during severe fault conditions.
With its 1-pole configuration, compact modular construction and high fault-current capability, the S801S-B8-R is well suited to industrial distribution, control, auxiliary and commercial electrical circuits. ABB order code 2CCS861002R0085 identifies this specific 8 A Type B model.

Reliable High-Performance Circuit Protection
Miniature circuit breakers such as the ABB S801S-B8-R automatically disconnect a protected circuit when excessive current results from an overload or short circuit. The thermal trip responds to sustained overload conditions, while the electromagnetic trip provides rapid interruption during severe short-circuit faults, helping protect conductors and connected electrical equipment.
The Type B characteristic makes the S801S-B8-R suitable for appropriate circuits where normal starting currents are relatively low and a sensitive magnetic trip response is required. Combined with the S800S platform's high breaking-capacity class and current-limiting operation, it provides dependable protection for demanding distribution and control systems.
Typical Applications
- Industrial electrical distribution systems.
- Control and auxiliary circuits.
- Industrial control panels and switchgear.
- Commercial electrical distribution systems.
- Circuits with relatively low normal inrush currents.
