Tronic Surface Isolator 4-Pole 40 Amps (415V)

In electrical engineering, an Isolator switch is used to ensure that an electrical circuit is completely de-energized for service or maintenance. They are only used for breaking the circuit and are often found in electrical distribution and industrial applications, where machinery must have its source of driving power removed for adjustment or repair. Disconnectors can be manual or motor operated and may be paired with an earthing switch to ground the portion that has been isolated from the system for ensuring the safety of equipment and the personnel working on it
