The Schneider Electric EZC100N3080 is a 3-pole EasyPact EZC100N moulded-case circuit breaker (MCCB) with a thermal-magnetic TM-D trip unit, rated 80 A at 40 °C ambient and 80 A at 50 °C. The TM-D trip combines a thermal bimetal for overload protection and a magnetic coil for short-circuit protection. Breaking capacity is the key selection parameter for fault duty. This breaker carries an N breaking capacity code with an Icu of 10 kA at 440 V AC. At 400…415 V AC the Icu rises to 15 kA, and at 380 V AC it reaches 18 kA. For DC applications, the Icu is 5 kA at 125 V DC (1-pole) and 5 kA at 250 V DC (2-pole). This MCCB is a Category A device, meaning it is not specifically designed for selectivity under short-circuit conditions with other breakers downstream — coordination studies should account for that.
The EZC100N3080 is a fixed-mount MCCB intended for backplate mounting in distribution panels or enclosures. Its dimensions are 130 mm height × 75 mm width × 60 mm depth. The 25 mm connection pitch matches standard busbar or cable-lug spacing. Both line and load connections are front-facing, simplifying wiring access in a panel layout. The IP20 degree of protection means it is finger-safe but not sealed against moisture — install it inside a cabinet rated for the environment.
