The Wico 1P/C20A/4.5kA is a single-pole miniature circuit breaker (MCB) designed to protect low-voltage networks from overload and short-circuit conditions, as well as infrequent manual switching. With a 20A rated current and curve C tripping characteristic, it suits higher-current resistive and moderate inductive loads in domestic and light-commercial installations.

The device clips onto a standard DIN 35 mm rail and meets EN 60898-1 and CE requirements. Its IP20 rating makes it appropriate for enclosed indoor distribution boards and consumer units.
