info

Littelfuse advocates the use of LET series fuse holders with a permanently installed solid neutral in high humidity and corrosive environments where a watertight 600V product is required.

The LET series features an integrated lug on the line side of the circuit, this ensures that there is nothing protruding from the load side of the product that could allow for an unsafe electrical touch point.
