Why Choose the ABB S802N-B20 Miniature Circuit Breaker?
The ABB S802N-B20 is a high-performance 2-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in demanding commercial and industrial installations. Part of the proven ABB S800N high-performance circuit breaker series, it combines a rated current of 20 A with a high 36 kA breaking capacity.
Featuring a Type B tripping characteristic, the S802N-B20 is suited to circuits with low to moderate inrush currents, including general-purpose resistive loads and appropriate distribution circuits. Its thermal and electromagnetic tripping mechanisms provide dependable protection against sustained overloads and short-circuit faults, while the current-limiting S800N design supports rapid fault interruption.
The S802N-B20 provides two protected poles in a compact DIN-rail format and is designed for integration into distribution boards, machinery panels and industrial control systems. ABB order code 2CCS892001R0205 identifies this specific 20 A Type B version within the S800N range.

Reliable High-Performance Circuit Protection
Miniature circuit breakers such as the ABB S802N-B20 automatically disconnect electrical circuits when excessive current results from an overload or short circuit. Thermal tripping responds to sustained overload conditions, while electromagnetic tripping provides rapid interruption of severe short-circuit currents, helping protect conductors and connected equipment.
The S800N series is engineered for applications requiring substantially higher fault-interruption capability than conventional miniature circuit breakers. Its compact modular construction, current-limiting performance and comprehensive accessory compatibility make the S802N-B20 a practical choice for demanding commercial and industrial electrical distribution systems.
Typical Applications
- Industrial electrical distribution panels.
- Commercial distribution boards.
- Machinery and automation control cabinets.
- General-purpose resistive load circuits.
- Control and auxiliary power circuits.
- High fault-level installations requiring high-performance circuit protection.
