protectors for mains supplies and power distribution systems Effective protection for power distribution systems
Installation

Install in parallel, within the power distribution board or directly on to the supply feeding equipment. At distribution boards, the protector can be installed either on the load side of the incoming isolator, or on the closest outgoing way to the incoming supply. Connect, with very short connecting leads, to phase(s), neutral and earth. On supplies over 100 amps, phase/live connecting leads should be fused with either 63 or 100 amp high rupture capacity (HRC) fuses, a switchfuse, MCCB or type 'C' MCB.
