Circuit Breakers

Protect an electrical circuit from damage by an overcurrent or short circuit.

A circuit breaker cuts the flow of current whenever the electrical wiring in a building has too much current flowing through it. It is one of the most important safety mechanisms to protect your property or electrical appliances from damage. In this category, you will find a wide selection of industry leading brands of high, medium and low voltage circuit breakers as well as related parts and accessories. Whether you are looking for an AC circuit breaker, oil circuit breaker, air circuit breaker, air blast circuit breaker or HVDC circuit breaker, you will definitely find something for your protection, distribution, control as well as management of power in your electrical system.

A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by an overcurrent or short circuit.

There are three basic circuit breaker varieties: standard breakers (which include both single-pole and double-pole circuit breakers), ground fault circuit interrupter circuit breakers (GFCIs) and arc fault circuit interrupter circuit breakers (AFCIs).

Standard circuit breakers come in two varieties: single-pole breakers and double-pole breakers. These are simpler breakers that monitor the cadence of electricity as it circulates an indoor space. It keeps track of electricity in electrical wiring systems, appliances and outlets.

The circuit breaker is a switching device which also offers protection by tripping & cutting off the supply to load in case of fault. Primarily the circuit breakers are used for switching different kinds of loads in Industries, Buildings, Commercial Complexes, and Hotels,

This is also known as an 'open' circuit. Open circuit voltage is measured when there is no current flow through the circuit. There are three basic types of circuits: Series, Parallel, and Series-Parallel.

A circuit is a complete path along which electricity flows. The essential elements in a basic electrical circuit consist of: A source, load, and ground. Electricity cannot flow without a power source (battery), a load (bulb or resistor-electrical device/ component) and a closed conductive path (wires connecting it). Electrical circuits consist of wires, wire connectors, switches, circuit protection devices, relays, electrical loads, and grounds. The circuit shown below has a power source, fuse, switch, a lamp and wires connecting each into a loop. When the connection is complete, current flows from the positive terminal of the battery through the circuit to the negative terminal of the battery.

The MCB is largely used in low circuit current, while MCCB is used for the heavy current circuit. The MCB is used for low energy requirements (domestic purposes), whereas the MCCB is used in high energy requirement regions (large industries).

With reliable and efficient power distribution products and system solutions. Among them, circuit breakers are capable to make, breaking and carrying rated current in the circuit. And able to protect circuits and equipment in the case of overload, short circuits and under-voltage. Circuit breaker featured with compact size, modular design, high breaking capability, zero flying arc and environmentally friendly.


MCB stands for Miniature Circuit Breakers. The MCB is an electromechanical device that switches off the circuit automatically if an abnormality is detected. The MCB easily senses the overcurrent caused by the short circuit. The miniature circuit has a very straightforward working principle. Additionally, it has two contacts; one fixed and the other movable.


On the other hand, MCCB is an abbreviation for Molded Case Circuit Breaker. The MCCB is a protective device protecting the circuit from overloading. Additionally, it has a switch that is operated manually for tripping the circuit. The device features two arrangements, one for the overcurrent and one for the over-temperature. Moreover, the MCCB consists of bimetallic contact, which contracts and expands when the MCCB temperature changes.


RCCB stands for Residual Current Circuit Breaker. RCCB is also known as RCB or RCD. RCD stands for Residual Current Device, while RCB stands for Residual Current Breaker. RCCB is an electrical wiring device that disconnects the circuit as soon as it detects a current leak to the earth wire. It also protects against electric electrocution or shock caused by direct contact.


RCBO stands for Residual Current Breaker with Over-Current. The RCBO combines the functionality of an MCB and RCD/RCCB. When there is a current leakage, the RCBO trips the entire circuit. Consequently, internal magnetic/thermal circuit breaker components can trip the electronic device when the circuit is overloaded.
