Reliable, strong and versatile, MRI resistors are the ideal solution for a wide range of employments from 1,5 to 60 KW. With “IP20” to “IP33” protection, for indoor or outdoor use, they consist in a variable number of RPTM resistors mounted inside a galvanized steel box (“Zinc” colour), also available with epoxy resin protection, with the requested “RAL”.
Provided with a ceramic mini-thermostat, MRI resistors can be connected from the bottom or also, through cable-glands, from the side. Characteristics of protection and performance are referred to a MRI resistor laying horizontally on its bottom side with no obstructions to the air inlets.
