MCBs

A Miniature Circuit Breaker or MCB is increasingly commonly used instead of a fuse to protect the circuit in a low voltage electrical network. It has several advantages in comparison to a fuse, as it works in any abnormal condition of the electrical circuit, whether due to a fault or a current overload. An MCB is far more sensitive to overcurrent than a fuse, and faster to restore power because it is not a sacrificial system, i.e. it doesn't requiring rewiring or replacement once tripped, only resetting. It is also safer to handle than a typical fuse, and allows easier identification of fault points on the circuit.

The consumption of electrical devices is ever-increasing, together with the resultant demand on electrical systems. In the event of a short-circuit or overload, MCBs cut the connected circuit safely and reliably, offering secure protection against damage to electrical devices and systems. They generally have two different mechanisms, a delayed thermal tripping mechanism providing protection against overloads, and a magnetic tripping mechanism protecting against short circuits.

Modern MCBs are easier than ever to assemble and install. They are uniformly designed, and come with a range of accessories which can expand to include additional functions, making them ideal for all kinds of application. At Rowse Automation we can offer an extensive collection of MCBs, including Single Pole, Double Pole and Triple Pole options in a series of different ratings, plus supporting accessories such as auxiliary switches, busbar systems and end caps for busbar isolation.
