The Schneider Electric C60H4P20AC is a 4-pole, 20 A miniature circuit breaker from the Multi9 C60H range. For higher fault currents, the IEC 60947-2 ratings go up to 50 kA Icu at 250 V DC, which matters if this breaker is specified for a DC bus application.
The 4-pole body takes 72 mm width, which is 8 modules of 9 mm pitch — standard for the Multi9 family. Depth is 73 mm, height 81 mm. The toggle handle gives local ON/OFF indication and a contact position indicator confirms the state visually. If you need earth-leakage protection, it requires a separate Vigi block — not integrated.
