1.3 Thermal Protector
1) This pump is fitted with an automatic reset thermal protector for overload protection.
This device shuts off the motor power supply circuit automatically to prevent burn-out if the motor
temperature rises due to a pump fault which prevents rotation, or if load becomes excessive.
Operating temperature : 120

℃
2) It is recommended that additional protective devices (eg. earth leakage breaker, motor breaker) be
fitted.
