Description of Operation
The NOVA LBS Load Break Switch is a three phase vacuum switch
designed for distribution electrical systems
is a three-phase, vacuum
interrupting switch designed for electrical distribution systems through
15/27 kV.
The NOVA LBS is designed and tested to be compatible with the LBC control
Eaton type. The NOVA LBS has an alimentation interface by the control.
The solid polymer insulation system does not rely on a gaseous, liquid, or foam
dielectric. The NOVA LBS is highly resistant to ozone, oxygen, moisture,
contamination, and ultraviolet light. The NOVA LBS has three solid-polymer
interrupter modules, a current transformer encapsulated by interrupt module
and a standard aluminum (or stainless steel if requested) enclosure for the
mechanism with protection rating IP54 or IP67. It is suitable for operation in the
temperature range of -40°C to +60°C
to +55°C.
