Panele rozruchowo-zabezpieczające ESC

Electrical control units to protect single-phase and three-phase bore-hole pumps.The units guarantee the electric pump protection from:

• overloads
• missing phase (only three-phase version)
• short circuit
• dry running protection

The display shows the operating condition with its LEDS:

• In operation (green ON)
• Water level to low (Yellow) - automatic restart tes (Stand by)
• Dry level (red) motor disconnected (No Water)
• Overload (red) - motor disconnected (Overload)

The water level is not controlled with electrode probes but through the changes in the cos (power factor) of the motor In case of dry running operation the system checkes automatically 4 times, whether the water level permits an auto-restart; thereafter the motor stays disconnected (No Water).

• protection level IP 43
• Operating temperature range: from 0°C to 40 °C
