LR2 Thermal Overload Relay

Yueqing Etec Electric Co., Ltd. [China]

LR2 Thermal Overload Relay can be used with LC1 contactor as Magnetic starter, also can be install as single unit

LR2 Thermal Overload Relayare 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.
