EZC400N3400N
Schneider Electric EZC400N3400N Easypact EZC400N 3-pole 400 A moulded case circuit breaker 36 kA. The Schneider Electric EZC400N3400N is a genuine Easypact EZC400N moulded case circuit breaker, 3-pole with all three poles protected and a fixed TM-D thermal-magnetic trip unit rated 400 A at 50 °C on a 400 A frame. Built to EN/IEC 60947-2, EZC400N3400N offers an ultimate breaking capacity Icu of 36 kA at 400/415 V AC 50/60 Hz, Ics of 18 kA, 690 V AC rated insulation voltage and 6 kV impulse withstand, matching the 400/415 V 50 Hz networks used across Egypt and the GCC. It gives overload and short-circuit protection, is suitable for isolation, and mounts fixed on a backplate with IP20 protection in a 255 x 185 x 140 mm body. It is applied as a main low voltage switchboard incomer or tie, as a feeder to large motor control centres in water treatment and cement plants, and as a distribution feeder in food and beverage and oil and gas installations.
