Miniature Circuit Breakers

Miniature circuit breakers are the backbone of safe, modern electrical systems — and Clopal brings you the most reliable, certified, and affordable range available online in Pakistan. Whether you are upgrading a home distribution board, wiring a commercial building, or building an industrial control panel, Clopal's miniature circuit breaker (MCB) collection has the right solution for every load, every pole configuration, and every budget.

What is a Miniature Circuit Breaker (MCB)?

A miniature circuit breaker (MCB) is an automatic electrical safety device that protects your circuits against two of the most dangerous electrical faults — overloads and short circuits. Unlike traditional fuses that require wire replacement after every fault, an MCB miniature circuit breaker simply trips and resets, saving you time, money, and risk. Once the fault is cleared, the breaker can be switched back on immediately — making it the preferred circuit protection device for homes, offices, factories, and commercial setups across Pakistan.

How Does a Miniature Circuit Breaker Work?

Every Clopal miniature circuit breaker uses dual-mode protection to keep your electrical system safe:

• Thermal Protection — A bimetallic strip heats up and bends during sustained overload conditions, gradually tripping the breaker before wiring or appliances are damaged. The thermal response is intentionally slow, allowing short-duration overcurrent conditions — such as motor startups — to pass without unnecessary tripping.

• Magnetic Protection — A powerful magnetic field is induced during a short circuit or sudden fault current, triggering an instant trip to interrupt the circuit immediately. This rapid response minimizes damage to connected appliances and wiring.

Together, these two mechanisms deliver complete overload protection and short-circuit protection — meeting IEC 60898 standards for electrical safety.

Wide Range of MCB Ratings & Pole Configurations

Clopal offers a comprehensive range of miniature circuit breakers across current ratings from 0.5A to 63A, covering every residential, commercial, and industrial application:

• Single Pole MCB — For lighting circuits, low-power loads, and individual residential circuits

• Double Pole MCB — Simultaneously disconnects live and neutral lines for complete circuit isolation

• Triple Pole MCB — Designed for three-phase commercial and industrial systems

• Four Pole MCB — Full protection for three-phase systems with neutral, ideal for large industrial panels

All Clopal MCBs feature DIN Rail mounting (EN60715, 35mm) with a fast-clip mechanism for quick, secure installation in any distribution board or control panel. Terminal sizes support up to 25mm² wiring with a tightening torque of 2.5Nm, ensuring solid, safe connections every time.
