ENHANCED TECHNOLOGY
3.1. INTERRUPTER
The vacuum interrupter of the recloser can provides versatilities to operate trip/close with the
ratings and capacity based on the fully capable of interruption.
The closing status of the contacts is held by contact springs that provide the required force at all
condition of contact wear.
As a vacuum interrupter is fully sealed for the lifetime of the recloser and it requires only a small
contact stroke and low interruption energy. it is suitable for application of magnetic actuator
mechanism and also vacuum interrupter has a capability of a large number of operations, which is
ideal for the recloser’s application.
Thus, vacuum interrupter with magnetic actuator provides a high reliability in operation and
minimum maintenance if the replacement of the vacuum interrupter is required with any reasons,
please consult with manufacturer.

3.2. MAGNETIC ACTUATOR
The magnetic actuator designed by the newest technology delivers force to the interrupter. Since
the magnetic actuator consumes low energy, actuator switching operation can be simply achieved
through rectifying circuit with the low voltage AC 110 or 220V supplied from an external power
sources and battery charged with the low voltage sources.
