Type 3 surge protector PSL2-8/230 TNS

class III2-polemonobloc

PSL is the range of surge protection devices (Type 3 / Class III) for very fine protection of sensitive equipment, in accordance with IEC 61643-11. DIN rail monobloc format. • Suitable as the final stage of protection in panels with Type 2 protection devices installed upstream. The residual voltage left downstream is less than for Type 1 or 2. They should be installed as close as possible to the equipment being protected. • Exclusive devices for TNS or TT earthing systems for single- and 3-phase networks. • Remote and visual indication of life status of the protection device. • Reversible chassis to allow cable entry from above or below. Mechanically polarized cartridges depending on the network voltage, to avoid possible cartridge replacement errors. • Biconnect - two types of terminal: for rigid or flexible cable and for fork type comb busbar.
