The thermal-magnetic trip unit gives you both overload protection (thermal bimetal) and short-circuit protection (magnetic coil) in one package, so no separate relay or CT is needed for basic feeder protection. ## Mounting and integration — fixed backplate, front connections This breaker mounts fixed to a backplate — no DIN-rail clip, so plan for screw-fixing into the enclosure gland plate. Both line and load connections are front-facing, which keeps wiring accessible for panel builders but means the busbar or cable entry needs to come from the front plane. Connection pitch is 35 mm, matching common busbar spacing. ## Selectivity and coordination — what the Category A rating tells you This breaker is Utilisation Category A, meaning it is not specifically designed for cascading selectivity with downstream breakers under short-circuit conditions — it will trip fast on a fault, which is fine for a main or feeder breaker where you want to clear the fault quickly, but if you need full selectivity with downstream MCCBs, you would want a Category B breaker with a short-time delay. The 3t protected poles with neutral unprotected is typical for a 3-phase + N distribution board where the neutral does not need overcurrent protection.","metaTitle":"Schneider Electric EZC250N4125 EasyPact EZC250N 125A 4P MCCB","metaDescription":"Schneider Electric EZC250N4125 EasyPact EZC250N MCCB, 125A thermal-magnetic trip, 20kA Icu at 440V AC, 4 poles.
