MCCB 3P 320-800A 70KA 380/415VAC MICROLOGIC 2.0 MANUALLY OPERATED

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.
