Thermal overload protection relay LR1 JRS1 VRS1

1.Used with CJX2(LC1) contactor 2.Rated voltage up to 660V 3.Rated current up to 80A 4.Telemecanique (Shineider) standard

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.
