Moulded Case Circuit Breakers

When standard miniature circuit breakers are no longer enough, a moulded case circuit breaker steps in — delivering the high breaking capacity, robust construction, and reliable fault protection that industrial panels, commercial main boards, and heavy-load distribution systems demand. Clopal brings you a complete range of MCCB moulded case circuit breakers in double pole, three pole, and four pole configurations, covering current ratings from 30A all the way to 150A — built for the toughest electrical environments in Pakistan.

What is a Moulded Case Circuit Breaker (MCCB)?

A moulded case circuit breaker — commonly known as an MCCB — is a heavy-duty electrical protection device housed in a heat-resistant, injection-moulded insulating casing. This robust enclosure is what sets the moulded case breaker apart from a standard miniature circuit breaker (MCB): it can handle significantly higher fault currents, higher breaking capacities, and heavier continuous load ratings without degrading over time.

Like an MCB, an MCCB moulded case circuit breaker provides dual-mode protection — thermal protection against sustained overloads and magnetic protection against instantaneous short-circuit fault currents. However, where a standard MCB typically covers current ratings up to 63A, a moulded case circuit breaker begins where MCBs leave off — handling 30A, 60A, 100A, and 150A loads with a far greater ability to safely interrupt large fault currents without damage to the breaker or the panel.

It is equally important to distinguish a moulded case circuit breaker from a moulded case switch. A moulded case switch is a manual isolation device only — it has no automatic overload or short-circuit trip mechanism. An MCCB moulded case circuit breaker, on the other hand, provides full automatic protection, making it the correct choice wherever both switching and protection are required in a single device.

Why Choose an MCCB Over a Standard MCB?

There are specific situations where a moulded case circuit breaker is the right and often the only suitable choice:

• Higher current ratings — Standard MCBs cap out at 63A. Clopal's MCCB moulded case circuit breakers handle continuous loads from 30A up to 150A, covering main incomers and heavy sub-distribution circuits that exceed MCB capacity.

• Higher breaking capacity — An MCCB can safely interrupt much larger fault currents than a standard MCB, making it essential for industrial environments where short-circuit levels are high.

• Heat-resistant moulded casing — The porcelain and moulded insulating body of a moulded case breaker withstands the heat generated by heavy loads and fault interruptions far better than standard MCB housings, ensuring long service life even in demanding conditions.

• Multi-pole main protection — MCCBs are the standard choice for main incomer protection in three-phase industrial panels, protecting all three phases and neutral simultaneously with a single coordinated trip.

MCCB Applications — Where Moulded Case Breakers Are Used

Clopal's moulded case circuit breakers are the protection device of choice across a broad range of demanding applications in Pakistan:

• Industrial distribution boards — Main incomer and sub-distribution protection for factories, manufacturing facilities, and industrial plants

• Commercial buildings — Main panel protection for shopping centres, office towers, hospitals, and hotels with high three-phase load demands

• Pump stations & water treatment — Protection for high-current three-phase pump motors and water management systems

• Generator panels — MCCB as the main breaker on generator output distribution boards

• Transformer secondary protection — MCCB as the first protective device downstream of a transformer secondary winding

• Large residential incomers — Main switch and protection for high-consumption residential properties with heavy single-phase or three-phase loads
