The Schneider Electric C60H4P20AB is a 4-pole miniature circuit breaker from the Multi9 C60H range, rated 20 A at 30 °C with a B-curve trip characteristic (magnetic tripping between 3 and 5 times In). It carries a 10 kA Icn breaking capacity at 230/400 V AC per EN 60898, and higher Icu ratings per IEC 60947-2: 15 kA at 400...415 V AC, 30 kA at 230...240 V AC, and 50 kA at 250 V DC for the 4-pole configuration.
Under IEC 60947-2 for industrial applications, the Icu (ultimate breaking capacity) reaches 30 kA at 230...240 V AC and 15 kA at 400...415 V AC. The Ics (service breaking capacity) is 7.5 kA at 230/400 V AC per EN 60898, meaning the breaker can be reclosed after clearing a fault at that level without replacement. The 4-pole DC rating of 50 kA Icu at 250 V DC makes it suitable for DC distribution panels in telecom or solar combiner boxes.
Installation and wiring
Fixed mounting on 35 mm DIN rail. The toggle actuator provides ON/OFF local indication and a contact position indicator confirms isolation status per IEC 60947-2. The 4-pole unit occupies 8 x 9 mm pitches (72 mm wide, 81 mm high, 73 mm deep).
