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 overloading, or there is a pump fault which prevents rotation.
2) Always fit other protective devices (eg earth leakage breaker, motor breaker) in addition to
the overload protection relay.
