LR7 Series Thermal Relay 1.Rated Voltage:up to 660V 2.Rated Current: up tp 38A 3.Standard:IEC60947-4-1.

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.2.Motion Characteristic: Three-phase Balance Motion Time
