LANCASTER HYDRO-FORCE™
4” ENCAPSULATED SUBMERSIBLE MOTORS
SINGLE PHASE TWO-WIRE & THREE-WIRE, ½ -1 HP, 230 V
EQUIPPED WITH LIGHTNING ARRESTORS
TECHNICAL FEATURES
Two-Wire Design
• Split-phase induction run (IR) design with built-in electronic starter connected in series to a high resistance
auxiliary start winding – no capacitor required – electronic starter controls disengagement of start winding as a
function of starting time and starting voltage.
Three-Wire Design
• Capacitor-start induction run (CSIR) design – control box required –
Control box quick-disconnect design disconnects control box components from the electrical system when the
lidisremoved–willretrotF.E.Q-DcontrolboxesofsameHPandvoltage.
Control box components include a 230V voltage relay for easy installation, two ground terminals, cable
terminals up to AWG 8, and a start capacitor for higher starting torque.
Control box painted steel enclosure with multiple knockouts is rated NEMA 3R for indoor or outdoor
installation.
