Series Thermal Over-load Relay Usage and its scope of appliance RDC6 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 Model and its implication Code for installation mode (Z for combination mode, F for separated mode) Rated operating current (A) Design serial No. Thermal Relay Enterprise code Normal operating condition and installation condition 3.1 Ambient temperature: -5℃~+40℃, and the average value within 24h does not exceed +35℃； 3.2 Altitude of the installation place does not exceed 2000m; 3.3 Atmosphere condition 3.3.1 Humidity The relative humidity does not exceed 50% when it is at +40℃, it allowed relatively high humidity at the relatively low temperature, for example, the relative humidity reaches 90% when +20℃, and it should take special measurements when there produced the condensation on the product due to the temperature variation. 3.3.2 Grade of pollution: 3 3.4 Installation condition 3.4.1 Installation category: III 3.4.2 Installation position: installed at the normal position, the gradient between the installation side and the vertical side does not exceed 5°, and without obvious vibration and impact. 3.5 Protection grade: IP 20 Main technique parameter 4.1 Rated operating current, setting current adjusting scope, suited AC contact model and recommended fuse mode for the thermal relay to see table 1
