DEAD LINE – Unique design of Viper-ST magnetic actuator system provides for local & remote operation if AC power is lost
OPERATION PRINCIPLE – The Viper-ST recloser monitors the circuit using internal multi-ratio current transformers and voltage sensors. Sequence operations, tripping and overcurrent sensing is an automatic function. Each phase module incorporates a magnetic actuator and drive assembly. Control can be set for three distinct operating modes for maximum application flexibility
MANUAL TRIP – Operation of the hookstick operable manual trip handle trips and locks out the recloser
