Notes:
®
1. Can be used with 380V - 415V motors.
2. Type indicates motor power rating and motor
type.
3. Nominal supply current at nominal voltage.
4. Motor starting current under nominal conditions.
5. Use external junction box for drop cable sizes
larger than 4mm
Prevents operation under
conditions where motor cur-
rent may exceed safe levels
due to bound pump or other
fault condition. Detection is
based on current heating
capacity measurement to
prevent unnecessary nui-
sance tripping.
Prevents system dama-
ge due to factors such as
continuous rapid cycling and
excessive motor thermal cy-
cling caused by waterlogged
tank or faulty pressure
switch.
Indication shows normal ope-
ration or other condition.
Dry-run, Over Current, Rapid
Cycling, Over Voltage and
Under Voltage are indicated.
