JR28-13 thermal relay

JR28 - 13 thermal relay is used in circuits with AC 50~60Hz, rated insulation voltage of 690V, and rated current within its applicable range (the specific value needs to be specified and is not mentioned here). It is used for overload and phase failure protection of AC motors. This type of thermal relay has two installation methods: combined installation (can be directly inserted into a contactor) and independent installation. When installed independently, it can be installed using a standard guide rail or by screws. It has two modes of automatic reset and manual reset (optional). It has a stop button that can disconnect the normally closed contact. It also has a test button that can be used to check the tripping and reset conditions.
