JR26 Series Thermal Relay

1.Application

JR26 thermal relay is suitable for overload protection of AC motor operated on 8-hours dutyor uninterupted duty. The overload protected AC motor with frequency 50Hz, voltage up to660V, current up to 30A. Several functions provided by these relays are: phase-failure protection,temperature compensation. The product conforms to IEC60947-4-1 stardand.
