LV Moulded Case Circuit Breaker (Rccb)
Moulded Case Circuit breakers are manufactured to meet IEC/EN 60947-2 and CE standards. These units are the main safety feature for different electrical setups. They work well with industrial cabling, heavy-duty motors, large lighting systems, and generators. Our MCCBs handle higher current demands than standard options. This keeps your systems secure and running smoothly, even under heavy electrical loads.
L.V MCCB fulfils 4 different functions;
- Close and Trip the circuit
- Protection against Overload
- Protection against Short Circuit Current
- Protection against Earth Leakage Current ( with the combination of Earth Leakage Relay and Toroidal Transformer

Frequently Asked Questions
What does a Moulded Case Circuit Breaker actually do?
An MCCB acts as a dependable protector for your electrical system. It monitors the system continuously, and if it detects a short circuit or overload, it could cause issues. It quickly shuts off the power to prevent issues. This safeguards your wires and motors, helping to ensure they remain safe and operate efficiently.
Which is better, MCB or MCCB?
It depends on what you want to power. For a house or small shop, a standard MCB is usually enough. It can handle up to 63A or 100A. For larger industrial jobs or main control panels requiring high power, an MCCB is better. It’s designed to handle that extra pressure.
What are the four types of moulded circuit breakers?
There are four main types of moulded circuit breakers. They are usually classified as Type B, C, D, and K/Z. Each type manages different current surges from equipment such as motors or transformers. The key difference is in their tripping curves. These curves show how each one reacts to surges. Type B, C, D, and K/Z breakers all have their own perks, so it’s essential to choose the right one for the job.
What is the current MCCB price in Pakistan?
The current MCCB price in Pakistan isn’t fixed. It depends on the Ampere rating and the breaking capacity. Since we make and supply MCCBs locally, Jawad Electric can offer pretty competitive rates. We’ve got good deals for both single units and big industrial orders. Get in touch with us for the latest prices.
