Product Description
Recloser principle
Reclosers are used in overhead lines and in substations.Like circuit-breakers they are capable of switching normal and
fault currents. They are equipped with sensors and controller being the protection and control device. In case of a temporary line fault, they can trip and reclose up to four times, thus avoiding longer network interruptions.

Recloser cycle
In case of a network fault, the recloser opens and recloses several times. In case of temporary faults, the automatic reclosing significantly reduces the outage times. While the trip settings for each operation can be set individually.
Design of switch unit
Each vacuum interrupter is embedded in a solid-insulated pole made of weather-proof cycloaliphatic epoxy-resin. The vacuum interrupter is vertically mounted inside the pole, providing a long service life. Each pole is equipped with an integrated current transformer and a resistive voltage sensor.
Operating mechanism
The recloser is operated by a magnetic actuator,the actuator is a bi-stable system, locked in the end positions by permanent magnets.If not in operation, the magnet coils do not consume any power. The operating mechanism housing is made of stainless steel for outdoor applications. it also accommodates the position indicator and a mechanical operations counter.
Mechanical lockout
The recloser can be tripped manually. If the handle is pulled, the recloser opens and is simultaneously locked out electrically and mechanically. The handle stays extended, thus indicating the interlocked state. To close the recloser again, the handle must first be pushed back to the operation position in order to release the lockout.Then the recloser can be closed electrically via the controller.
