High-Performance MCB Devices
Our extensive collection of MCB devices are a vital part of any electrical system. These Miniature Circuit Breakers automatically interrupt the power supply when an overcurrent or short circuit is detected in a circuit, preventing damage to wiring and connected appliances. Unlike traditional fuses, an MCB can be easily reset after a trip, which makes them an essential component for modern consumer units.
We offer MCBs in various ampere ratings and with different tripping characteristics to suit diverse applications. For example, "B curve" MCBs are ideal for residential use, protecting against moderate overloads, while "C curve" MCBs are more tolerant to higher inrush currents, making them suitable for commercial and industrial settings with appliances like motors or fluorescent lighting. All our MCBs are designed to comply with the latest safety standards and feature easy DIN rail mounting. Whether you need them for a new installation, to replace an old fuse box, or to add to an existing panel, selecting the correct MCB ensures your electrical system continues to run smoothly and safely.
