RME is a small-sized switchgear consisting of 1-4 integrated functional blocks
Design
The RME monoblock consists of the following:
- hermetically sealed stainless steel enclosure, “sealed” for the entire service life, in which all active parts, load break switches or circuit breakers with earthing disconnectors having short-circuit interrupting capability are housed;
- from 1 to 4 cable compartments for connection to networks or transformers;
- LV compartment;
- actuator compartment;
