Prex float switch applications

PREX is suitable for water level control in professional and residential applications:

  • Pumping stations and deep wells
  • Level control in wells, tanks, and cisterns for clean water, rainwater, and drainage
  • High-level alarm switch
  • Dry-run protection for low-level detection
  • Compatible with single-phase pumps up to 2 HP

Features

The reinforced structure and body design ensure robustness in environments where vibration, liquid movement, and hydraulic pressure can compromise standard float switches.

The dedicated sealing system reduces the risk of water infiltrations, ensuring stable operation during prolonged submersion or in deep well installations.

The 20(8)A 250V rating allows direct control of pumps up to 2 HP
