China supplier CNKA's newest 100 Amp 4-pole AC MCCB offers a competitive price list and utilizes plastic insulators as the casing to isolate conductors from grounding metal parts. When the current exceeds the set value, the MCCB automatically cuts off the current. Typically, these circuit breakers come with thermal magnetic trip units or solid-state trip sensors, depending on the model. The tripping unit can be either thermal magnetic or electronic. Common 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 both industrial and civil electrical circuits, ensuring reliable protection.

CNKA 100 amp 4 pole ac mccb Working principle

 

1 The main contact of a low-voltage circuit breaker can be closed either manually or electrically. Once closed, the free release mechanism locks the main contact in the closed position. The coils of the overcurrent and thermal releases are connected in series with the main circuit, while the coil of the undervoltage release is connected in parallel with the power supply.

2 In the event of a short circuit or severe overload, the armature of the overcurrent release is activated, prompting the free release mechanism to operate and disconnect the main contact from the circuit. This function helps prevent damage to equipment and ensures the safety of personnel by protecting against overloads and short circuits. Low-voltage circuit breakers are widely used in various electrical systems and serve as a crucial protective device.

CNKA 100 amp 4 pole ac mccb FAQ

 

Q: What is the difference between MCCB and ACB?
A:CNKA MCCB is a molded case circuit breaker designed to protect electrical circuits from overcurrent due to overloads or short circuits. It has a lower current rating compared to an ACB, which is an air circuit breaker using air as the arc-quenching medium for higher current ratings.

Q: What is the disadvantage of MCCB?
A: The cost of an MCCB can be significantly higher compared to MCBs and fuses. Additionally, maintaining an MCCB can be more complex due to its insulated casing, requiring more effort in upkeep.
