Main isolating switch disconnector SBN340 3P 40A Hager

Product description

Anisolation switch is a device that has two functions to perform. First of all, it conducts current under rated conditions, as well as during overloads, short circuits or other faults. This is because the so-called safe isolation gap is then created, which creates a lot of safety space. It acts as a fuse. This is because it is the main emergency switch.

3-pole isolation switches are used to disconnect phases and to disconnect the power supply to specific parts of the installation. The product is mounted with screws (not included) surface-mounted to the substrate, and this only thanks to the TH-35 rail. It is possible to add auxiliary contacts (HZC311 and HZC312) on the left or right side of the apparatus. It is the most widely used electrical switch in current flow control systems.
