APDM630-3four phase switch for NH fuses up to 630A with three phase operation
General Description
This model is suitable for switching and protecting LV overhead lines, and/or to include a protection when doing a connection to low voltage underground systems.
The design of this equipment allows the opening and closing of the thr ee phases simultaneously and independently from the neutral, which is clearly identified to prevent its disconnection in rigidly landed systems. If required, it can be easily transformed in a single phase operation switch as the standard model APDM 630.
It can be connected with terminals lugs (APDM630-3) or directly with its connectors (APDM630-3C). Each phase and the neutral have an indicator which show if the fuse or th e 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.
