Example: Wilo-Control ECe-B 2x12A-T34-DOL-WM
ECe Version with Easy Control switchgear:
- EC = switchgear for fixed-speed pumps
- ECe = switchgear for electronically controlled variable-speed pumps
B Control for pressure-boosting systems
2x Max. number of pumps that can be connected
12A Max. rated current per pump in amperes
T Mains connection:
M = alternating current (1~)
T = three-phase current (3~)
34 Rated voltage:
- 2 = 220/230 V
- 34 = 380/400 V
DOL Pump activation type:
- DOL = direct on line
- SD = star-delta
WM Wall fixation
Connect the switchgear directly to the pump and the mains. Intermediate switching of ad-
ditional electronic start-up controllers, e.g. a frequency converter, is not permitted!
The switchgear does not have its own explosion protection class. Do not install the
switchgear in potentially explosive areas!
