We manufacture and supply. The product is certified. The RTL thermal relay is designed to protect electric motors from long-term current overloads. RTL thermal relays provide protection against phase current asymmetry and phase loss. RTL thermal relays are produced with a current range from 0.1 to 80A. RTL relays can be installed either directly on PML contactors or separately from contactors (in the latter case, they must be equipped with KRL terminal blocks).
