Operating temperature:-40°C to+60°C

5.Application scenarios

Motor protection:Detect the operating status of the motor,including parameters such as current,voltage and temperature,and promptly detect and respond to possible electrical faults or overload conditions.

Cooling time constant simulation:When the motor is running or stopped at a load below the overload pickup set point,the relay simulates the cooling process of the actual motor.

Start prohibition and emergency restart:Prevent the motor from starting when its thermal capacity is insufficient,or reset the supervision timer in an emergency to allow the hot motor to start.

RTD bias:Based on the measured current,but taking into account the effects of ambient temperature and motor cooling conditions,an RTD(Resistance Temperature Detector)bias adjustment can be made to more accurately reflect the actual operating state of the motor.
