JR-36 scope of application
JR36 series thermal overload relay is suitable for AC 50Hz/60Hz, voltage to 690V, current to 0.25-160A long-term operation or intermittent long-term AC motor overload and phase failure protection. The thermal relay has phase failure protection, temperature compensation, automatic and manual reset, and reliable operation.
This product complies with: GB14048.4, IEC60947-4-1 and other standards.
Thermal relays are only installed separately. This product and CJT1 contactor constitute the QC36 type electromagnetic starter.
