3-phase motor wiring diagram (RPV064-120)
The motor is equipped with an automatic reset type thermal protector in the coil. Therefore, operation restarts automatically when the temperature of the motor
drops to safety level after thermal protector activation. To prevent a danger by unexpected restart, provide a recovery switch which uses switch and relay as like
above circuit diagram to restart the pump.
●
Thermal protector activation temperature : Open (motor stop)
▶
130
±
5ºC, Close (motor restart)
▶
90
±
15ºC
Note: The motor is equipped with an automatic reset type thermal protector in the
coil. Thermal protector activates to stop the motor in case the temperature
inside the motor exceeds the specified temperature below. Operation
restarts automatically when the temperature of the motor drops to safety
level. To prevent a danger by unexpected restart, make sure to turn off the
main power supply before maintenance and inspection.

Thermal protector activation temperature
Open (motor stop)
▶
130
±
5ºC, Close (motor restart)
▶
90
±
15ºC
Note: Therefore, in the case of the circuit (left figure) given in the handling
instruction of motor, after activation of thermal protector, operation will be
resumed automatically when motor temperature falls.
In order to prevent a risk by unexpected reboot, please take safety
measures when operating the pump, such as making a self-hold circuit
using relays and switches.
