The Schneider Electric EZC100N3063 is a 3-pole EasyPact EZC100N moulded-case circuit breaker with a 63 A thermal-magnetic trip unit (TM-D) rated at 50 °C. It delivers 10 kA Icu at 440 V AC 50/60 Hz per IEC 60947-2, with higher interrupting ratings at lower voltages — 25 kA at 220–240 V AC and 18 kA at 380–400 V AC.
Breaking capacity and application context
At 415 V AC it holds 15 kA, and at 380–400 V AC it reaches 18 kA, giving headroom for systems with higher available fault current at lower line voltages. The 5 kA Icu at 125 V DC (1-pole) and 250 V DC (2-pole) covers DC distribution sub-circuits, though the primary application is AC distribution per the device application field. The IP20 finger-safe terminals and IK07 impact resistance suit panel-mount installations where incidental contact is possible.
Fixed-mount via backplate with front-front connections (both line and load sides). The toggle actuator provides positive contact indication — you can visually confirm the contact position without removing the front cover.
