JR36 series thermal overload relay, hereinafter referred to as thermal relay. Mainly used for overload protection and phase failure protection of three-phase AC motors with AC 50Hz, rated voltage up to 690V, and current up to 160A. It can also be combined with CJT1, a substitute product for CJ10, to form a magnetic starter.

The JR36 series thermal overload relay is an improved design on JR6B, and its installation method and dimensions are exactly the same as JR6B, making it a substitute product for JR6B.  


The JR36 series thermal overload relay not only has overload protection and phase failure protection functions, but also has the following structural characteristics:
4.1 Temperature compensation is available;
4.2 Check the flexibility of movements;
4.3 There is a convertible manual reset or automatic reset;
4.4 There is a button for manually disconnecting normally closed contacts.  

5.1 Protection Characteristics
5.1.1 The action characteristics of three-phase load averaging are shown in Table 1
