Product Description

China suppliers ICHYTI Newest 100 amp 4 pole ac mccb Price List use plastic insulators as the casing to isolate the conductor and grounding metal parts. When the current exceeds the set value, the molded case circuit breaker can automatically cut off the current. Normally, molded case circuit breakers include thermal magnetic trip units and solid-state trip sensors, which are used for different models.

The tripping unit can be divided into thermal magnetic tripping and electronic tripping. The commonly used rated currents include 16, 25, 30, 40, 50, 63, 80, 100, 125, 160, 200, 225, 250, 315, 350, 400, 500, and 630 amperes. Molded case circuit breakers are widely used in industrial and civil circuits.

ICHYTI 100 amp 4 pole ac mccb Working principle

◉ The main contact of the low-voltage circuit breaker can be closed by manual operation or electric closing. Once the main contact is closed, the free release mechanism will lock the main contact in the closed position. The coils of overcurrent release and thermal release will be connected in series with the main circuit, while the coils of undervoltage release will be connected in parallel with the power supply.

◉ When there is a short circuit or severe overload in the circuit, the armature of the overcurrent release will be pulled in, and the free release mechanism will also act accordingly, causing the main contact to disconnect the main circuit. This can prevent circuit overload and short circuits from causing harm to equipment and personnel. Low voltage circuit breakers are widely used in various electrical systems and are a very important electrical protection device.

ICHYTI 100 amp 4 pole ac mccb FAQ

Q: What is MCCB and ACB difference?

A: CHYT MCCB is a type of circuit breaker that is designed to protect electrical circuits against excessive currents resulting from overload or short circuit conditions. It features a molded case design and has a lower current rating compared to an ACB, which is an electrical switching device utilizing air as the arc quenching medium.

Q: What is the disadvantage of MCCB?

A: The investment required for an MCCB can be considerably higher when compared to both MCBs and fuses. Additionally, the upkeep of an MCCB entails a more complicated process due to its insulated casing.
