Pump Motor Start Box, Relay Control

Features:
Single-phase or three-phase, CE rated pump control panels.
SJE EMD series are CE Rated electromechanical control panels designed to control one or two submersible singlephase or three-phase electric pumps in water and wastewater applications. They are provided with a thermal overload protection relay incorporated in the IP55 weather-proof cabinet. The control panels operate the pumps based on the liquid level from signals provided from fl oat or pressure switches.Application:
• Water supply pumps
• Wastewater pumps
• Many more motor control applicationsSpecification:Input Power: 1~ 50/60 Hz, 230V ±10%
