20. Technical data - single-phase pumps
20.1 Supply voltage
1 x 200-240 V - 10 %/+ 10 %, 50/60 Hz - 2 %/+ 2 %, PE.
Recommended fuse size
Motor sizes up to 1.1 kW: Max. 10 A.
Standard as well as quick-blow or slow-blow fuses may be used.
20.2 Overload protection
The overload protection of the E-motor has the same
characteristic as an ordinary motor protector. As an example, the
E-motor can stand an overload of 110 % of I
