We manufacture and supply. The product is certified. Thermal overload relays of the RTT-1, RTT-2 series are designed to protect three-phase asynchronous squirrel-cage induction motors from overcurrents of unacceptable duration, including those occurring during the loss of one of the phases. The relays are used as components in electric drive control circuits in AC circuits with a voltage of 660V at a frequency of 50 or 60Hz, and in DC circuits with a voltage of 440V. Warranty period - 2 years from the date of commissioning.
