Mitsubishi low voltage circuit breakers prolong the lifespan of electrical equipment.

For over a half of a century Mitsubishi low voltage circuit breakers meet the needs of market. Including the WS-V series equipped with a new breaking technology, Mitsubishi Low Voltage Circuit Breakers have various lineups depending on the electric power market and the machinery.

Air Circuit Breakers

Make electrical equipment multi-functional by means of Mitsubishi air circuit breakers that are suitable for protection of the main circuit.

Air circuit breakers have many advantages, among them adding higher reliability during switching. They can be used to extend the area of selective coordination trough expansion of the rated short-time withstand current, for use in main circuit ports.

Air Circuit Breakers (ACB) AE-SW

Air Circuit Breakers (ACB)

This kind of breaker is used as the main power breaker of the supply such as buildings, factories and ships etc. and satisfy the various needs.

Molded Case Circuit Breakers

Wide assortment of products that is highly suitable for protection against overload and short-circuit conditions.

These are basic products for the protection of low voltage circuits. The WS-V series, Mitsubishi's latest series of Low Voltage Circuit Breakers, offers a number of different versions, including "F-style" small size breakers, with improved usability.

Molded-Case Circuit Breakers (MCCB) NF

Molded-Case Circuit Breakers (MCCB)

The molded case circuit breaker (MCCB) opens and closes a low voltage circuit, and breaks the fault current (an overload current or short circuit current) automatically, to protect the wirings/conductors of the circuit.

UL 489 Listed Molded Case Circuit Breakers with Ground Fault Protection NV-U

UL 489 Listed Molded Case Circuit Breakers with Ground Fault Protection

This kind of breaker complies to UL 1053 and CSA C22.1No.144.

Circuit Breakers for Use in Particular Applications

Upgrade your electrical equipment by using products suitable for your particular application.

If it is considered as proper when the standard MCCB/ELCB is not chosen to use in a special characteristic of the load, the special breaker is needed.

Isolation Switches DSN

Isolation Switches

On creating an isolation switch (DSN) by omitting the overcurrent tripping device of a MCCB, it can be used as a switching device with high operating capacity.

Accessories and Related Components

Suitable for extending circuit breaker functions.

There are many different internal and external accessories. They can be used to make breakers safe and convenient.

Internal Accessories AL, AX, SHT, UVT

Internal Accessories

These accessories are installed inside the breaker. AX indicates electrically the status of the breaker. AL indicates electrically the status of the breaker trip. SHT makes the breaker trip electrically by remote operation. UVT releases the breaker when the control voltage is dropped.
