OVER LOAD RELAY

Thermal overload relays can be used in the circuit of 50Hz or 60Hz, rated insulation voltage 660V, rated current 0.1-93A for protecting the phase brick when the electric motor is overload. The relay has a different mechanism and temperature compensation. It is the most advanced thermal relay in the nineties in the world. The products comply with IEC60947-4.
