must
be
adhéred to for all electrical devices.
Use of an electrical protective device on the pump motor protects :
- The motor : in the event of overvoltage or pump seizure, the resul-
ting excess current can destroy the motor windings and possibly the
starter.
- The pump : in the event of a locked pump rotor due to contamina-
ted oil, presence of particles, or non- "lubrication, serious damage
may occur.

be used
; the
mechanism includes a quick-opening switch controlled by a bimetal-
lic strip, which is activated by excessive current draw.
Cholce of size
Two operating modes must be considered : starting and continuous
duty.
Starting :
During starting, the torque furnished by the motor to start the pump
is considerable :
- In a single-phase motor : use of the auxiliary phase and a starting
current which can reach § to 7 times the rated current :
- In a three-phase motor : excess
current 2 to 2.5 times the rated
current.
Starting In a Cold Environment (less than 18°C/65°F)
In certain cases, when the pump has to startin a cold environment, or
with slightly contaminated or viscious oil, the current after starting
cap
~mnain high until the pump oil heats up (10 to 20 minutes) :
- 4
»+phase motor : twice the rated
current.
- thn ve-phase motor : 1.5 times the rated current.
These values are given as examples, and can vary according to the
type of pump and oil used.
Continuous Duty
This is the normal pump operating mode after about 1 hour of opera-
tion. The current is then slightly less than the rated current of the
motor.
As a consequence, dual integrated protection should be used : one
for continuous duty (which will also protect the pump for starts under
normal conditions — oil clean, temperature above 18°C, etc.), and
one for start conditions.
When
starting : the time the pump
takes to get up to full speed
should not exceed 15 seconds.
