  JR26 & LR7 Series Thermal Relay
JR26
JR26		 JR26 Series Thermal Relay

1. Application
   JR26 thermal relay is suitable for overload protection of AC motor operated on 8-hours duty or uninterupted duty. The overload protected AC motor with frequency 50Hz, voltage up to 660V, current up to 30A. Several functions provided by these relays are: phase-failure protection, temperature compensation. The product conforms to IEC60947-4-1 stardand.
