Gustav — Wed, 15 Oct 2025 06:55:04 +0000

Moulded Case Circuit Breakers (MCCBs) are essential electrical protection devices designed to safeguard circuits from overloads, short circuits, and faults. Widely used in residential, commercial, and industrial applications, MCCBs provide robust protection for electrical systems, ensuring safety and reliability. At Generator Parts, you can find a comprehensive range of MCCBs to meet your electrical needs, available both online and in-store.

Understanding Moulded Case Circuit Breakers

MCCBs are advanced circuit breakers encased in a moulded, insulated housing, typically made of durable plastic.

Circuit Breakers – Choose From a Huge Range

Gustav — Wed, 12 Jul 2023 11:07:07 +0000

A huge range of the best quality circuit breakers is available by browsing our website. A circuit breaker is an essential component for any building. If a building has too much current flowing through it, a circuit breaker will cut the power until it can be rectified.

What is a circuit breaker?

An electromechanical device, its function is to protect electrical installations that are used in electrical distribution boards. The circuit breaker was developed by Hugo Stoltz in 1923. Since then, further developments have resulted in a more sophisticated circuit breaker, including the single-pole, two-pole, three-pole, and the four-pole circuit breaker.

Circuit breakers are essentially protection devices. They interrupt electrical current during an overload or faulty situation and thus help prevent damage to electrical systems.

Different types available

We offer a broad range of circuit breakers in different sizes. These include miniature circuit breakers, moulded case circuit breakers, as well as air draw out circuit breakers.

A miniature circuit breaker is an automatic switch that opens when excessive current flows through the circuit. Furthermore, it can be reset quickly.
A moulded case circuit breaker works on the same principle as a miniature circuit breaker. However, it has a moulded case, and can also provide isolation of the circuit for maintenance. A moulded circuit breaker has a higher interrupting capacity. As such, this means that it can handle larger loads and is generally used for industrial applications like generators.
An air draw out circuit breaker is a switching device capable of making, carrying and breaking currents under normal and abnormal circuit conditions such as those of a short circuit. A draw-out circuit breaker can be physically removed from its enclosure creating a visible break in the circuit.

Our range of circuit breakers includes the smaller model suitable for use in a home, right through to the large circuit breaker ideal for large applications. Choose from the MCB63C/1P-6AMP 1-Pole Mini Circuit Breaker, right through to the ACB 1600AMP/4-Pole Air Circuit Breaker – Draw-Out and many in between.

A circuit breaker is an essential safety device. Ensure your building has the right circuit breakers in place.

New Circuit Breakers

Gustav — Thu, 10 Sep 2020 09:08:42 +0000

Does your home need new circuit breakers? Not quite sure what they are? When electricity enters your home, it goes to a circuit breaker box. Here it is divided into a number of circuits. Each circuit is protected by a breaker. They detect and stop excess current in its tracks. A circuit breaker will trip when there is an overload or short circuit, cutting off current to the problem line until it can be safely looked at. In a nutshell, its basic function is to interrupt current flow after a fault is detected.

How do I know a circuit break needs to be replaced?

If certain appliances in your home keep getting interrupted by the breaker, or when the breaker itself will not stay reset after you return it to its “on” position.
A burning smell from the breaker box could mean that a replacement is necessary.
A breaker that is hot to the touch should be replaced.
If you see burned parts, frayed wires, or other obvious signs of wear anywhere in the breaker box, it’s likely time to replace one or more of its components.

Which circuit breaker is best?

Circuit breakers are available in 3 different voltage capacities. Each is made to accommodate a specific amount of electricity. Low-voltage thermal magnetic circuit breakers are best suited for smaller homes. Standard circuit breakers are typically used for most electrical outlets in the home. They may be single- or double-pole. GFCI circuit breakers will cut power to the circuit not only when there is an overload or short circuit, but also when a line-to-ground fault is detected. They are necessary in parts of the home where electrical outlets are located close to water sources, such as outside and in the kitchen and bathroom. AFCI circuit breakers interrupt the power supply when they sense an electrical surge or abnormal path that could cause an electric fire.

We offer a range of different types and sizes of circuit breakers for you to choose from. From the smaller 3-pole circuit breaker to the 800 m 4-pole circuit breaker, you can rest assured you will find precisely what you need. Each product has the option of a whatapp helpline when you need additional information.
