£84.83
The ABB S302P-C20 (SKU: 2CDS382001R0204) is a high-performance 2-pole miniature circuit breaker (MCB) designed to protect industrial electrical circuits against overloads and short circuits. As part of the robust ABB System pro M Compact S300P series, it provides dependable circuit protection for installations requiring a high short-circuit interruption capacity.
The S302P-C20 combines delayed thermal overload protection with rapid electromagnetic short-circuit protection, helping safeguard cables, machinery and connected electrical equipment. Its compact modular design supports straightforward installation inside switchboards, distribution boards and control panels, while compatibility with standard DIN rail systems simplifies panel construction and maintenance.
With a 20 A rated current, Type C tripping characteristic and 2-pole configuration, this circuit breaker is suitable for circuits with moderate inrush currents. Its 25 kA breaking capacity makes it an excellent choice for demanding industrial and commercial applications where prospective fault currents may be high.
Miniature circuit breakers automatically disconnect electrical circuits when excessive current is detected. The thermal tripping mechanism responds to sustained overload conditions, while the electromagnetic mechanism reacts rapidly to short-circuit faults. This combined protection helps prevent damage to cables, equipment and electrical infrastructure.
The ABB S300P series is engineered for applications requiring high breaking capacities and dependable operating performance. The Type C characteristic allows the S302P-C20 to tolerate moderate temporary inrush currents while maintaining reliable fault protection for industrial equipment and commercial power distribution systems.
