1、FN3-12、FN3-12R、FN3-12R/S負荷開關系戶內裝置的高壓電器。適用于交流50Hz、6KV或12KV的網絡中,作為開斷和閉合負荷及過荷電流之用,亦可用作開斷和閉合空載長線�?蛰d變壓器及電容之開關。帶有RN3型熔斷型的負荷開關(FN3-12、FN3-12R/S)可切斷路器,作保護開關之用。
2、本負荷開關可配用CS3型及CS2型手動操作機構進行操作。
1、FN3-12、FN3-12R、FN3-12R/S Series are used in the
network of AC 50Hz、6KV or 12KV for breaking or closing
load and over-load current. they are also used in
breaking and closing no-loading . The switch or no-load
transformer and capacitor with KN3 type fuse box. Can
cut off short-circuit for protecting switch.
2、They can be equipped with CS3 type and CS2 type
handle operating mechanism.
