MA Analogue Borehole Control Box 4″ 0.55kW 220V

Standard analogue starter for single-phase borehole pumps, matched to a 0.55kW 4″ motor. Houses the run capacitor, on/off switch and thermal overload protection.

Must match your motor’s kW rating – the capacitor is sized for the motor.

Which borehole controller do I need?

• MA Analogue Control Box (220V single phase, 0.37–2.2kW) – the basic starter for single-phase pumps. It houses the start capacitor, on/off switch and thermal overload. Lowest cost, but it does not switch the pump off if the borehole runs dry.
• 20Y Intelligent Pump Controller (220V single phase, 0.37–2.2kW) – digital controller with dry-run protection, over/under-voltage and overload protection, automatic restart and a display showing voltage and current. Recommended for most 220V boreholes, especially low-yield boreholes that can run dry.
• Y1 Digital Protection Controller (380V three phase, 0.37–7.5kW) – protects three-phase borehole pumps against dry running, phase loss, phase imbalance, overload and bad voltage.
• 30Y Intelligent Pump Controller (380V three phase, 5.5–15kW) – heavy-duty controller for larger three-phase pumps such as 6" borehole pumps.
• Variable Speed Drive (VSD) – soft-starts the motor and adjusts pump speed to demand, saving power and reducing wear. Used on the 525V pump sets and for constant-pressure systems. See our VSD range.

Always match the controller to your pump motor’s power (kW) and supply voltage. Not sure? Contact us with your pump model and we’ll confirm the right controller.
