Description
A complete assembly consists of the recloser control unit,
the vacuum interrupter assemblies, and the operating
mechanism housing.
Recloser tripping employs stored spring energy. When the
trip solenoid is actuated by the 24 Vdc trip signal, the stored
spring energy is released to open the recloser. The 24 Vdc
trip signal is originated at the recloser control. The 240 Vdc
supply is not required to trip the recloser. An external 240
Vac source is required to operate the drive motor. A 120 Vac
input power supply accessory is also available.
Type VSA reclosers are electronically controlled by Eaton’s
Cooper Power series recloser controls.
