Telephone Metal Oxide Gapless 33kv Metal Oxide Varistor Surge Arrester
33KV Surge Arrester Description
SPD (Surge Protective Device or called surge arrester) is an appliance designed to protect electrical devices from voltage spikes. A surge protector attempts to regulate the voltage supplied to an electric device by either blocking or by shorting to ground voltages above a safe threshold. We have spark gap, MOV and Spark tube type for different protection area.
For the whole building lighting protection, 30kA-60kA, 40kA-80kA, 50-100kA, are available, however, 30kA-60kA is the most common one. As we know, one building have two unita, one is A, the other one is B, for A or B, surge arrester 20/40kA will be your best selection. What's more, we also can provide the one such as surge arrester 5-10kA,especially 10-20kA to strongly protect the single room, 5-10kA to protect a single unit electric device.
