Thermal protection relay RDR6 series

1 NO/NCthree-phasefor electric motors

RDR6 series bimetal type thermal over-load relay is suitable for the circuit of AC50Hz/60Hz, rated operating voltage Ue: 380V, rated impact voltage Uimp (kV): 8, rated current 0.10~93A, as the use of over-load, break phase and protection for the circuit and motor. Thermal relay with the functions and characteristics of break phase protection temperature compensation, setting current adjusting, optional selection of auto-reset and manual reset, action indication signal, insulation separation of NO, NC auxiliary contacts, small installation section, and various installation mode. Thermal relay is designed, manufactured and inspected according to GB14048.4 ►Normal operating condition and installation condition 3.1 - Ambient temperature: -5aC~+40'C, and the average value within 24h does not exceed +35'C : 3.2 - Altitude of the installation place does not excccd 2000m; 3.3 - Atmosphère condition 3.3.1 - Humidity The relative humidity does not cxcccd 50% when it is at +40*0, it allowed relatively high humidity at the relatively low température, for example, the relative humidity rcachcs 90% when +20*C, and it should takc spécial mcasurcmcnts when there produccd the condensation on the product duc to the température variation. 3.3.2 - (ïrade of pollution: 3 3.4 - Installation condition 3.4.1 - Installation category: III 3.4.2 - Installation position: installcd at the normal position, the gradient between the installation side and the vertical side does not cxcccd 5°, and without obvious vibration and impact. 3.5 - Protection grade: IP 20
