Terminals available outside the framework on terminal board protected by a cover
The casing of the RME series uses RHP tubular cemented spark plugs. The frame of the enclosure is made of galvanized steel and has an IP20 degree of protection. The power terminals are available on a clamp and are located within the lid, which can be opened. The box is equipped with thermal pad with proper terminal in the lid. The RME series is only available in the version with UL marking.
The RME family provides for 7 models with power ratings from 0.6 kW to 6 kW. The UL certification provides for a derating of the rated power of approximately 50%. The ohmic value varies from 1.5 Ω to 270 Ω. The maximum voltage of use is 800 V.
What are the overload conditions?
The resistance can be overloaded with respect to its nominal power based on the working cycle (insertion and rest time). For duration pulse less than one second, the overload permissible also depends on the ohmic value.
What is the temperature of the resistance?
The temperature of the resistance depends on the power that it will dissipate. The rated power value indicated in the data sheet refers to a temperature on the upper wall of about 200°C.
The resistance can be mounted horizontally or vertically on the wall. The terminals should always be kept low to avoid heating during the working of the resistance.
