Pole Mounted fuse switch disconnector 630A
This model is suitable for switching and plotecting LV overhead lines ,and/or to include a plotection when doing a connection to low voltage underglound systems . The design of this equipment allows the opening and closing of the three phases simultaneously and independently from the neutral ,which is clearly identified to plevent its disconnection in rigidly lmlded systenls .If required ,it can be easily transfonned in a single phase operation switch as the standard model APDM 630 It can be connected with terminals lugs(APDM 630-3)or directly with its connectors (APDM 630-3C) . Each phase and the neutral have an indicator which show if the fuse or the blade are installed .The closure of the cap allows the switch to be closed with or without the fuse preventing the risk of leaving live parts exposed It can also be provided with a led to show the fusion of the fuses .
