MCCB 3P 18-25A 36kA

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 also has several pole options, namely, 1 pole, 2 poles, 3 poles, and 4 poles.

Characteristics of Molded Chase Circuit Breaker (MCCB)

• Mostly 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 this device is able to work automatically based on current and temperature conditions. In general, MCCBs usually use 3 phases because they are only used as protection for electric motors in the industrial world and also have a greater function than MCBs because of their greater specifications. Therefore, this device is only used as protection for electric motors in the industrial world.

Siemens’s (Molded Case Circuit Breaker) MCCB the new 3VA set new standards in terms of flexibility and variety of modular accessories. Standardized accessories suitable for use with several sizes of circuit breaker from all the 3VA ranges help to cut costs and save installation time.

The new 3VA1 molded case circuit breakers reliably perform all the tasks required for line protection and starter protection.
