These are industrial resistors with extremely high overload characteristics, which are mechanically very robust and non-inflammable, with excellent insulation and high dissipation capacity. Thanks to these characteristics, the RCE resistors are particularly well suited for load groups and in railroad traction applications.
The external protection of the resistor consists of a ceramic cement lining.
The resistive element consists of wire in Ni-Cr alloy or twisted constantan, on an extremely high quality elliptical ceramic support. The support is fastened by a stainless steel frame equipped with bores or slots for attachment.
The resistors can be produced with different specifications for the slots (type "A", "B" or "C").
The nominal power Pn shown in the table refers to resistors placed horizontally and free in naturally circulating air, with an environmental temperature of 25° C.
With forced ventilation the nominal power dissipation capacity of the resistor increases as a function of the air speed.
