EPB stands for Electrical Power Bar, and it is a device used to protect electrical equipment from voltage spikes or power surges. It is often found in industrial settings such as factories, warehouses, laboratories, manufacturing plants and other similar facilities. EPBs are typically connected directly to the main supply of electricity entering the facility and provide surge protection by diverting excess energy away from sensitive electronics before it can cause damage. The EPB will also sense when an overload has occurred on the circuit and shut off power until it can be reset manually or automatically depending on the type of model purchased. By providing reliable protection against damaging voltage fluctuations, EPBs help ensure that expensive machinery remains operational while helping to reduce costly downtime due to unexpected outages caused by power surges.
