Hubbell Industrial Controls, Inc. Euclid™ Lifting Magnet Controllers 4295 Resistor Type Automatic Discharge Specifications 4295 • March 2004 • Replaces July 1990 Features Front-Wired Front-Removable components. Mechanically interlocked "LIFT" and "DROP" contactors. Permanently connected discharge path completely independent from the line. High-Thermal capacity resistor discharge path. Peak magnet induced voltage limited to under 900 volts. Long electrical contact life. Minimum Maintenance. Dribble feature - Standard. Ventilated NEMA 3R Enclosure. Description The Euclid Type 4295 Magnet Controllers incorporate heavy duty time proven components arranged to provide optimum control of your lifting magnets. A mechanically rugged high thermal capacity discharge resistor assembly is permanently connected in parallel with the magnet and provides a safe discharge path for the stored magnetic energy. With Euclid magnet controllers, induced volts cannot return to the line, permitting rectified power supplies to be used without the added expense of special protective loads or by-pass circuits. Automatic Discharge Type Controllers The Euclid Type 4295 Automatic Discharge Type Lifting Magnet Controller provides a fast and clean release of magnet loads by applying full voltage reverse current to the magnet. The full voltage reverse current feature permits the operator to promptly return for another lift. The drop contactor is under the control of the operator's Master "Switch" and the discharge sensor module (DSM). When the operator's Master "Switch" signals the magnet controller to drop the load, the "LIFT" contactors (1L+2L) open. The stored magnet energy is dissipated in the discharge resistor. When the discharge voltage declines to approximately 300 volts, the discharge sensor module (DSM) energizes the drop relay (DR) which in turn enables the drop contactor (D) to close applying full voltage reverse current to the magnet and begin the adjustable time reverse current cycle. After the completion of the timed reverse cycle the drop relay (DR) and drop contactor (D) are de-energized. Type Controllers The Euclid Type 4295 Lifting Magnet Controllers are suited for many uses from light scrap handling to the handling of heavy billets of plates. It may be used with all types and makes of dc lifting magnets.
