1.Specification
LR1(JRS1,VRS1) series 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 0.1-80A under 8-hours duty or uninterrupted duty.Functions provided by these relays, are phase-failure protection, ON/OFF indication, temperaturecompensation, and manual/automatic reset.Applicable Standards: National Standard: GB 14048. International Standards: IEC 60947-4-1The relays can be mounted onto contactors or installed as single units.
2.Operation condition
(1)The altitude couldn t exceed 2000m.(2)Ambient temperature: -5 ~+55 and the average temperature no more than +35 in 24hours.(3)Atmosphere: Comparative humidity no more than 50% at max +40 , and it may be higher at a lower temperature. The lowest average temperature no more than +20 in the wettest month.The maximum average comparative humidity of this month couldn t exceed 90%, The change of temperature leading to dew on the product must be considered.(4)Class of pollution: Class 3.(5)The slope between installation surface and vertical surface couldn t exceed 5o.(6)Keeping away from explosive, corrosive and electric atomy.(7)Keeping dry.(8)The product should be used and installed at certain place without any shock, vibration etc.
