Relay RTT-211П designed for
protection of three-phase asynchronous motors with short circuit rotor against overcurrent
invalid duration, including those arising from the loss of one of
phases.
Electrothermal current
thermobimetallic relay RTT-321П for installation on magnetic contactors series
PMA-5000 PMA-6000, is designed to protect three-phase asynchronous
electric motors with squirrel-cage rotor overload invalid
duration, including that occurs when dropping one of the phases. Relay
intended for use as components in circuits
drive control in AC circuits with voltage 660 In frequency
50 or 60 Hz, DC voltage of 440 V. the Use
non-replaceable heating elements and rapid activation when a phase
and unbalance in the phases increase the reliability of protection of electric motors in comparison
with the bipolar performances. Data from the thermal relays have a temperature
compensation.
