1.3 Thermal Protection Relay
1) This pump is fitted with an automatic reset thermal protection relay 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.
2) It is recommended that additional protective devices (eg. earth leakage breaker, motor
breaker) be fitted.
