  JRS5 Series Thermal Relay
JRS5-12/Z
JRS5-12/Z		 1. Application
   JRS5 thermal relay is suitable for overload protection of AC motor operated on 8-houres duty or uninterupted duty. The overload protected AC motor with frequency 50Hz, voltage up to 660V, current up to 105A. Several functions provided by these relays are: phase-failure protection, temperature compensation, ON/OFF indication and manual/automatic reset. The product conforms to IEC60947-4-1 stardand.
