 Scope of application 




 JRS2 thermal relay is suitable for AC 50Hz, main circuit rated voltage up to 690V, current up to 630A power system for three-phase AC induction motor overload and phase failure protection. 

 Comply with GB14048.4 standards. 

 Type and meaning 



 Some common models are: JRS2-14.5 JRS2-25 JRS2-36 JRS2-45 

 Structural characteristics of 

 The full range of products with overload and phase failure protection; setting current can be adjusted, and most of the hot component tuning current cross-Cascade, user-friendly selection. -25 ° C to +55 ° C air temperature range, temperature compensation. Disconnect the normally closed contact of the test button and action instructions, free tripping function. With can prevent electric shock shields, with independence, into the contactor and rail variety of installation methods.
