213 JRS4-F series of thermal overload relay
1.Application

JRS4-F series of thermal overload relay is used in AC 50/60Hz, rated current 101A-500A in circuit, for protecting AC motor against overload or phase-breaking. Main for construction, mechanical, metallurgical and industries, protect motor against potential overload and phase-breaking
2.Main feature
The structure of JRS4-F series thermal relay are “layer2” three-dimensional layout, the lower is current transformer; the upper is JRS4-d thermal relay;
 With protection against overload and phase-breaking, temperature compensation, manual and automatic reset function, action release shower, device detect function, adjustable setting current and the advantage of d range thermal relay.
 Trip grade: class 10;
Strong arrangement function can be used combination with GSC2-F AC contactor and GSC4-NF reverse contactor; also can be used combination with other contactors in electrical apparatus circle.
