SJE AmpMaster®
International Version
The 20 amp rated SJE AmpMaster® pump switch is designed to directly control grinder and high head sewage pumps up to 1 1/2 HP at 125 VAC and 3 HP at 250 VAC in grinder and lift station applications, as well as septic tank effluent pump (STEP) systems.
The SJE AmpMaster® pump switch is not sensitive to rotation or turbulence, allowing it to be used in both calm and turbulent applications. It is available for pump down applications only.
Features

NOTE: This switch must be used with pumps that provide integral thermal overload protection. Certain pump applications may require the use of an external capacitor start kit.
A Pump Switch is designed for Horsepower (HP) rated loads and is not suitable for control (pilot duty) applications. It will fail prematurely when switching loads less than 1 Amp at 120 VAC. Select a float switch from our Control Switch offering for control applications.
