Why Choose the ABB S802S-C20-R High Performance MCB?

The ABB S802S-C20-R is a high-performance 2-pole miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection in demanding electrical installations. Part of the ABB S800S high-performance circuit breaker range, this model combines a rated current of 20 A with a Type C tripping characteristic, making it suitable for appropriately designed circuits with moderate starting and inrush currents.

The S802S-C20-R uses thermal and electromagnetic tripping mechanisms to protect conductors and connected equipment. The thermal trip responds to sustained overload conditions, while the electromagnetic trip provides rapid interruption during short-circuit faults. Its high 50 kA short-circuit breaking capacity makes it suitable for installations where substantial prospective fault currents demand high-performance circuit protection.

With its two-pole configuration and robust modular construction, the S802S-C20-R is suited to industrial distribution systems, machinery, automation equipment and electrical control panels. Its Type C characteristic provides a practical balance between fault protection and tolerance of moderate short-duration inrush currents, making it a versatile choice for commercial and industrial applications.
