Shunt Reactors (Inductive Load Reactors)

ENT.ERS Series
Shunt reactors are designed to compensate the capacitive power used by long
underground power lines, UPS, computers, electronic ballast, and energy saving
lamps.

ENTES shunt reactors are designed in European standards to have long

operating lives and endure difficult operating conditions. These devices which
designed to provide inductive load requirements have the CE mark.

Features;
Single or three-phase, highly conductive design with air gap
F isolation class insulation material on the windings resistant to 155 C
High quality copper or aluminum windings (copper coated terminal on
aluminum windings)
Custom designs to meet customer specifications
Thermal protection against overload
Vacuum impregnated varnish method that improves efficiency by reducing
heat losses, provides protection against humidity, and enables quiet operation
CE mark and compatibility with EN 61558 2-20
