CHINT MCCB WHITE SIZE 4P 400A

A CHINT MCCB 4P 400A (White and Black) is a Moulded Case Circuit Breaker used to protect high-current electrical distribution systems.

Uses

Protects electrical circuits from overloads and short circuits.

Acts as the main incoming breaker in three-phase distribution panels.

Safely isolates the power supply during maintenance or emergencies.

Protects large electrical equipment such as:

Industrial machines

Large motors

Transformers

Commercial buildings

Generator and solar power distribution panels



What the ratings mean

4P (4 Pole): Switches and protects all three phases (L1, L2, L3) plus the neutral, making it suitable for three-phase, four-wire systems.

400A: Designed to carry and protect circuits with currents up to 400 amperes. It trips automatically if the current exceeds safe limits or a short circuit occurs.


Common applications

Main distribution boards (MDBs)

Commercial and industrial electrical installations

Generator changeover systems

Large solar inverter AC output protection

Factory and workshop power distribution


Using a CHINT 4P 400A MCCB improves electrical safety by preventing damage to cables and equipment and reducing the risk of electrical fires caused by overloads or faults.
