JBY46 150 - 200 AMP Magnetic Latching Contactor

JBY 46 Magnalatch
Up to 60 VDC, 150 - 200 Amps

The MAGNA-LATCH TM Latched Low Voltage Disconnect Contactor is more compact than traditional low voltage disconnects. The permanent magnet holds the contact closed. Momentary power to the coil closes the contact, while a momentary reverse power signal to the coil opens the contact. The MAGNA-LATCH TM also uses the same bus bars available on traditional electrically held contactors.

Optional features of the MAGNA-LATCH TM include special coil voltage silver-plated bus bars, custom bus bars, mounting studs and nuts in bus bars, and additional auxiliary contacts. Screw coil terminals, side mounted feet for horizontal mounting and a rectifier for AC coil operation are additional optional features.

  • Coil heat is eliminated
  • Reduces need for redundant power control
  • 24 VDC units suitable for use on 48 VDC systems
  • Designed to remain closed for 20 years
  • Fail safe - contacts open or close only when appropriate signal is applied
