Surge Protector Type 1+2 (BC) 37.5kA 3P DS133R-230 C571503

Surge Protector Type 1+2 (B+C) — DS133R-230 (C571503)

DS133R-230 is a multi-pole surge protector designed for low voltage installations in three-phase systems. The device is designed as a combination of Type 1 + 2 protection, allowing for the discharge of nominal lightning impulses and surge impulses from the network (protection against both direct and indirect effects of lightning strikes). The DIN format design allows for installation in standard distribution boards and quick replacement of protective modules.
