The JK-MREC automatic circuit reclosers are designed for use on overhead lines as well as substation application for distribution line of up to 38 kV. The recloser is supplied with controller. The controller is a microprocessor based controller that provides the protection, and data gathering and communication function in the capacity of control devices inherently reliable and intelligent. The recloser combines the high reliability of vacuum interruption and high dielectric strength of epoxy mold, in a compact, maintenance-free unit. The magnetic actuator provides consistent performance and high reliability.
Epoxy molded(solid) insulation - environmental-friendly product No maintenance needed during its entire lifetime / Long mechanical and interrupting life Compact design Phase Fault, Ground Fault, SEF & Under/Over Frequency Protection Cold Load Pickup, Inrush restraints, Phase Sync. Check, Hot Ling Tag 58 TC curves(IEC,ANSI,Recloser-innate, 4 user-defined) Two RS 232 ports for communication with PC and SCADA system

This design incorporates three Independentmagnetic actuators: one for pole. This minimizes the number of moving parts.The actuator armature is rigidly coupled to thevacuum interrupter moving contact by a lineardrive insulator within the support insulator.
SWITCHING DEVICE
MAGNETIC ACTUATOR
● Increased rel iabil i ty with min. 10,000 Mechanical operation
● Simple design ● Bi-stable : No power required to hold contacts in open or closed. ● Three individual actuators and three-phase
simultaneous operation

INSULATING MATERIAL
● Advanced epoxy encapsulating material ● Light weight & compact design for easy
installation & handling. ● Improved performance in heavily polluted area ● Increased weather durability and improved aging
INTEGRATED SENSORS
● Three(3) current(1000:1 A, ± 5 %) and six(6)sensors integrated in epoxy module for protection, and line voltage/current measurement ,
INDICATOR/COUNTER
● Contact position indicator : Easily visible from the ground
● Operation counter to record recloser operation
VACUUM INTERRUPTER
● High interrupting capacity ● Very compact dimension ● Low chopping current, limiting inductive
switching overvoltage to safe values ● Axial magnetic field minimizing contact
erosion and ensure a very long and reliable life
