Electrical data: single-phase pumps

Note: Edwards recommends using regional supply protection of the maximum ratings specified in
and Table 10. Protection of a higher rating must not be used.
The dual-voltage, dual-frequency motor is designed for a single-phase electrical supply and is suitable
for 50 Hz or 60 Hz operation. The motor can be manually switched between nominal supply voltages of 110–120 V
and 220-240 V (refer to Section
When a cold pump is started, the motor will draw the start-up current shown in
seconds. An appropriate rated and pre-approved time-lag fuse must be used to prevent unnecessary fuse failure
during pump start-up (in accordance with local and regional electrical codes). Within five minutes, as the oil in the
pump warms up, the current drawn will slowly reduce to the full load current specified in
