DC Contactors JBY46 Tabs

		JBY46 150 - 200 AMP Magnetic Latching Contactor

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 optiona features.

Benefits:

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
