40 kv iv very high impulse voltage equipment intended to be installed at or near the intake to the installation such. Surge protection devices spds spds protect electrical and electronic equipment against transients originating from lightning switching of transformers lighting and motors.
Practical Tips For Installing Surge Protection Devices In Low
Hager spd wiring diagram. Protection for those devices connected to the telephone network. Looking for spd 4p monobloc 125ka class 1 with light indicator tt tns spa401. Circuit breakers and wiring systems. This higher energy spd typically a spark gap for a type 1 spd is required as lightning currents arise towards the protective conductor and as such this higher energy spd sees up to 4 times the surge current of the spds connected between the live conductors. A higher energy spd is used between neutral and the protective conductor. Hager have a domestic consumer unit that has a built in surge protection spd a type 100 amp rcds and they are call them 18th edition consumers units.
These transients can cause premature ageing of equipment downtime or complete destruction of electronic components and materials. The hager spd range of solutions may offer protection to prevent damage to this sensitive equipment by diverting the. Protection is assured in both common differential modes. Find all the information for devices on the official hager website. We look at the layout of this hager board.
