The Schneider Electric EasyPact EZC250N44225 is a 4-pole moulded-case circuit breaker (MCCB) from the EasyPact EZC250N series, fitted with a TM-D thermal-magnetic trip unit rated 225 A at 50 °C. The TM-D trip provides overload and short-circuit protection via a thermal-magnetic mechanism — the thermal element handles sustained overcurrents, the magnetic element clears high-fault events instantly. No earth-leakage protection is built in (specified as 'Without').
The EZC250N44225 carries a breaking capacity code 'N' and delivers 20 kA Icu at 440 V AC 50/60 Hz per IEC 60947-2. At 380–415 V AC the rating rises to 25 kA Icu; at 220–240 V AC it reaches 50 kA Icu. For DC circuits, it is rated 20 kA Icu at 125 V DC (1-pole) and 20 kA Icu at 250 V DC (2-pole). At 550 V AC the rating drops to 8 kA Icu — a key constraint if your line voltage runs high. The breaker is utilisation category A, meaning it is not intended for frequent switching of motor loads under normal conditions — it is a distribution breaker, not a motor-protective device.
Fixed-mount design for backplate installation. Front-front connections (both line and load side terminate on the front face), which simplifies busbar routing in a panel but means you need clearance in front for cable access. The connection pitch is 35 mm. IP20 finger-safe protection on the front; the enclosure itself is rated IK07 for impact resistance. Dimensions: 165 mm high, 140 mm wide, 60 mm deep.
Designed and tested to IEC 60947-1 and IEC 60947-2, with additional compliance to JIS C8201-2-2 and GB/T 14048.2.
