MCCB/NFB 4P 75A 30KA/415VAC

Molded Chase Circuit Breaker (MCCB) is an electrical component that functions as a safety and circuit breaker when a short circuit or overload occurs, which can cause damage to the electric motor and fire due to sparks. MCCB is more popularly used as security for large-scale electrical installations, for example, in malls, factories, offices, and various other industries. MCCB usually uses 3 phases because it is only used as a safety measure for electric motors in the industrial world. MCCB also has several pole options, namely, 1 pole, 2 poles, 3 poles, and 4 poles.

Characteristics of Moulded Chase Circuit Breaker (MCCB) : 

• Uses three phases.
• Ampere Rating: 100A–1000A
• Network frequency: 50/60 Hz
• Using thermal magnetic
• Can be set to Fixed or Adjustment

The main function of an MCCB (Molded Case Circuit Breaker) is as a protection device for electrical equipment against short circuits or excess electric current (overload) so as to avoid damage and fire. The MCCB device is equipped with a temperature sensor and current sensor feature so that this device is able to work automatically based on current and temperature conditions. In general, MCCB has a greater function than MCB because its specifications are greater and it uses 3 phases. Therefore, this device is only used as protection for electric motors in the industrial world.

This is a 75A circuit breaker for EasyPact EZC100H. This product can work below rated operational voltage(Ue) 550VAC at 50/60Hz and 250VDC. This version of product is designed 4 poles frame with detection on 3 poles,equiped TMD trip unit for thermal-magnetic protection. It is compliance with standard IEC60947, CE certification and some independent lab(KEMA,ASEFA,TUV) or third-party Tilva. This device is certified for operation in pollution degree III environment as defined by IEC60947, and pass the test of extremely atmospheric conditions. Device can be mounted vertically or horizontally in a metal enclosure,and against from safety risk by padlocking. This series have slots used for indication or voltage release auxiliaries positioning, depending on where it is inserted in the device behind the front cover of circuit breaker.
