Application
RDC5 series AC Contactor is mainly used in the circuit of AC 50Hz or 60Hz, rated voltage up to 690V, rated current up to 95V, for the use of remotely connecting and breaking the circuit, it also can be directly combined with thermal relay into electromagnetic starter to protect the circuit that may have overloaded operations. Contactor can also be equipped with accessories such as the block type auxiliary contacts group, air delay contact, mechanical interlock mechanism, etc. to combine into delay contactor, directional contactor, and star-delta starter. It conforms to the standard IEC/EN60947-4-1.
Normal operating condition and installation condition
3.1 Ambient temperature: +5ºC~+40ºC, average temperature within 24h does not exceed +35ºC
3.2 Altitude: does not exceed 2000m
3.3 Atmospheric condition: when the highest temperature is +40ºC, the relatively humidity does not exceed 50%; it can allow relatively high humidity when it is at relatively low temperature, for instance, it reaches 90% when it is at +20ºC it should take measurement when there have condensation occurred due to the temperature variation.
3.4 Pollution grade: 3
3.5 Installation category: IlI
3.6 Installation position: the gradient of the mounting surface to the vertical surface does not exceed ±5ºC
3.7 lmpact and vibration:product should be installed and used at the places without obvious shake, impact and vibration.
