KRAH GROUP
RMT_RCE model
GENERAL CHARACTERISTICS
Resistor in open version (IP00), consisting of wire-wound elements on ceramic cores assembled in banks; this type of resistor is suitable for industrial environments with limited vibration levels.
The cement coating applied to the winding ensures overall solidity, which makes it particularly well suited to overload operation — typical of neutral-point grounding of transformers or generators — while also providing good protection against contaminants.
In applications requiring a low inductance value, an Ayrton-Perry winding can be used.
