Miniature Circuit Breaker (MCB)
High-precision Miniature Circuit Breakers (MCBs) engineered with fast magnetic-thermal tripping mechanisms to provide rapid, reliable defense against current overloads and short circuits across electrical distribution panels.
Product Overview
Miniature Circuit Breaker (MCB)
When your electrical circuits need serious, dependable protection, PCG 10kA MCBs are engineered to step up to the challenge. With advanced current-limiting technology, high-speed operation, and a robust 10kA breaking capacity, they keep homes, offices, and industrial setups running safely and without interruption. Smart features like mid-trip fault indication, flame-retardant housing, and easy DIN-rail mounting make them as user-friendly as they are powerful. For heavy appliances and critical circuits, PCG MCBs deliver the kind of electrical security you can genuinely rely on.

Specifications
| IP 20 Degree Protection | Terminals are finger touch proof. Prevents electrical shock by accidental touch. |
|---|---|
| Padlocking Facility | Dolly can be padlocked in OFF position for personal safety during maintenance ON positing for extremely critical loads |
| Current Limiting Design Class 3 | Minimum let through energy under fault condition due to ultra-fast contact separation and rapid quenching of the arc. This reduces stress on connected loads and cables. |
| Indication | PCG MCB's have a clear & visible indicator to show it thermal is on or off |
| Din Rail Mounting | Two stage snapping device for simple effortless and rm seating on 35 mm Din Rail, easy & efficient mounting. |
| Combination Head Captive Screws | Safe and provides the flexibility of both +/- Head screwdriver. |
| Low Power Consumption | Cost effective and energy saving. The Watt loss of PCG MCBs is extremely low providing valuable energy savings over its entire life cycle. |
| Wide Range | 6.0 to 63 A; 1P, 1P+N, 2P, 3P, 3P+N & 4P configurations; B & C Tripping Characteristic |
| Air Circulation | When two poles are placed adjacent to each other, these channels form a tunnel resulting in effective air circulation around individual poles. |
| 2 Position Dolly | Clear indication of the operational status of device. |
| Housing | Made from high-grade engineered Polybutylene Terephthalate (PBT) for self-lubrication and reliable performance. Fire-retardant molded components with high dielectric strength ensure stability under elevated temperatures. |
| Operating Mechanism | Thermal–magnetic protection system combining a temperature-sensitive bimetal for overload protection and an electromagnetic device for large overloads and short-circuit response. |
| Superior Contact Mechanism | Fixed and moving contacts made with silver polish for extended lifespan, anti-weld performance, low contact resistance, reduced voltage drop, and minimal watt loss for energy efficiency. |
| High Tech Arc Blower | Efficient arc chute design that rapidly extinguishes arcs during overload or short-circuit conditions, enhancing safety and preventing damage. |
