A selector switch for an electrical panel is an electrical device within a circuit that primarily plays a role in protecting installations. The selector switch is generally a parallelepiped-shaped plastic casing, installed vertically. The control buttons are located on the front face of the casing and are therefore directly accessible.
The dimensions of a selector switch for an electrical panel differ according to the models. However, as an indication, most of the available models measure around 121 mm in length, 90 mm in width, and 92 mm in height. As a characteristic, a selector switch necessarily corresponds to a cutting voltage, for example, 1000 V, and a cutting current: for example, 30 A. Once one of these cutoff values is reached, the circuit is spontaneously deactivated. The device also corresponds to a temperature range predetermined by the manufacturer: for example, -30°C – +60°C. A selector switch for an electrical panel is equipped with a fuse that allows it to fully perform its protective device role. The brand LEGRAND, for example, has reliable and highly functional bipolar selector switch models.
