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 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.
