ABB - 7TCA085460R0112 3 PHASE SURGE PROTECTOR, 415V, TYPE 1+2+3, POWER SPD

Surge Protective Device, 3 Phase, 346-484 working voltage

This Furse, Type 1, 2 and 3 Tested, 25 kA Surge Protector has been designed to protect electrical devices from electrical voltage surges and spikes within an electrical circuit. Surge protectors are ideal for use on power distribution systems. Created to protect connected electronic equipment from transient over voltages connected to the mains supply such as computers systems, process control equipment and other valuable devices.

Versatile, this surge protector features a very low let-through voltage, with enhanced protection to IEC/BS EN 62305, between all sets of conductors ? phase to neutral, phase to earth, neutral to earth and full mode protection. The full mode designed is capable of handling partial lightning currents as well as allowing continual operation of protected equipment. This surge protectors offer an advanced pre-warning so you can stay protected with repeated protection in lightning prone environments.

This surge suppressor is easy to install in parallel within the power distribution board or directly (via fuses) on to the supply feeding equipment. At the distribution board this surge protector can be fitted either on the load side of the incoming isolator, or on the closest outgoing way to the incoming supply.
