Pump control & protection
Pump control panels
and motor protection
Start with the motor and the way the pump needs to operate. Level control, pressure switching, remote operation and two-pump duty are different requirements, even when the power ranges overlap.
Describe the operating sequence

BC1 and BC2 exterior examples with English label layouts. The enclosure, functions and electrical ratings depend on the quoted model.

From reference to requirement
The nameplate
is a useful first step.
Include the motor model, voltage, phase, frequency and rated current if available. Add the number of pumps and a short description of the required sequence.
Download Excel form- 01
Describe normal operation
What starts the pump, what stops it, and what signal provides that instruction?
- 02
Describe the installation
Control location, environment, sensing arrangement and any existing equipment.
- 03
Agree the exact configuration
Review the selected model, electrical ratings, protection functions, wiring information and included accessories.
Your next step
Explain how the pump should operate.
A short sequence and the motor details are more useful than selecting a control by its kW range alone.
