JRS2(3UA) THERMAL OVERLOAD RELAY 1.AC 50/60Hz, rated voltage 690V~1000A, 2.current 0.1A~630A long time continue

Application

JRS2(3UA) series thermal over-load used in AC 50/60Hz, rated voltage 690V~1000A, current 0.1A~630A long time continue and discontinuous circuit toprotect the AC current motor overload and phase failure. The safety andsteady quality can supply phase failure protection, temperature compensation,tripping indicator, manual and automatic reset button. It can be mounted plug-in with contactor or independent.Standard: GB14048.4/IEC60947-4-1

Operating conditions

Altitude: not exceed 2000mTemperature: -5°C~ +40°C, average temperature in 24 hours not exceed +35°CAir conditions:At mounting site, relative humidity not exceed 50% at the max temperatureof +40°C, higher relative humidity is allowable under lower temperature,relative humidity not exceed 90% at average temperature not exceed + 25°C, special measures should be taken to occurrence of dews ;Pollution degree: 3;Installation category: ⅢMounting conditions: inclination between the mounting plane and the verticalplane not exceed ±5 ;Impact and shake: the products should locate in the places where there are no obvious impact and shake.
