LRD Thermal Overload Relay

Product Detailed

1.LRD series thermal overload relay 2.thermal hermal relay 3.thermal relay 4.contactor relay 5.themal overload relay Specifications

LRD Thermal Overload Relay the new generation relay instead of LR2-D13.D23.D33

LRD Thermal Overload Relay are suitable for overload and phase-failure protection of AC motors with frequency of 50/60Hz, voltage up to 690V, current up to 0.1-150A under 8-hours duty or uninterrupted duty. Functions provided by these relays, are phase-failure protection, ON/OFF indication,temperature compensation, and manual/automatic reset. Applicable Standards: National Standard: GB 14048. International Standard: IEC 60947-4-1 The relays can be mounted onto contactors or installed as single units.
