Circuit breakers are electrical safety devices that are designed to protect an electrical circuit from damages caused by an overcurrent or short circuit. Its main function is to interrupt the flow of current to protect equipment and prevent the likelihood of a fire ensuing. As there are many types of circuit breakers, this blog will focus its attention on industrial miniature circuit breakers (MCBs).
With voltage fluctuation from power surges being quite common, engineers have invented new mechanisms to control power fluctuations in electrical systems. One such mechanism is miniature circuit breakers. MCBs are electrical switches that are automatically operated and are intended to prevent damage as a result of excess current. More than that, they are designed to trip during an overload or short circuit, protecting against electrical faults and equipment failure.
Small electromagnetic circuit breaks like MCBs can quickly detect and react to electrical faults. In particular, MCBs help switch a circuit to an open state when the current exceeds the set value. Therefore, their main purpose is to interrupt current flow and determine fault conditions. With their capacity, MCBs are widely used in a variety of applications, some of which will be outlined in the following paragraph.
MCBs find use in home electrical panels, safeguarding your home from electrical overload. Safer and more reliable than fuses, MCBs can handle large amounts of electricity, ensuring the equal distribution of electrical energy in all your devices. In lighting systems, MCBs play a critical role, distributing equal amounts of power to all light bulbs, fluorescent lamps, and more. Within the industrial sector, MCBs maintain small- and large-scale installations and applications by optimizing their energy flow. Beyond such uses, there are also a variety of circuit breakers, those of which include plug-in, bolt-on, and cable-in/cable-out variations.
Plug-in MCBs make their connection to the load center through being plugged in. A recessed clip at the end of the circuit breaker plugs into the electrical bus of the load center during installation. This type of MCB is often over others as it has a quick and easy installation.
Bolt-on circuit breakers are distinguished by the metal flange that protrudes their housing. A screw driven through this flange attaches the circuit breaker to the load center’s electrical bus.
Lastly, cable-in/cable-out variations offer arch chutes with 5-100A continuous in one, two, and three-pole designs, alongside steel frame calibration. More than that, they are equipped with ring tung termination and mounting options.
MCBs offer numerous advantages that benefit countless applications. First, they offer high ingress protection, making it touch-safe for operators. They are environmentally friendly as the latest generation of MCBs are composed of halogen-free thermoplastics. More than that, they can be recycled, allowing you to minimize environmental pollution. Beyond their compact and universal design, they have a long lifespan and can be operated with ease. Such characteristics make MCBs a go-to solution for many operations.
