Features:
• Hydrogen dielectric for power switching high
current loads
• 400 A carry, 2,500 A interrupt @ 320 Vdc
• Ideal for circuit protection, control, battery
switching, and main power safety disconnect
• Versatile power, voltage, and current
operating range: 28-1800Vdc tested
• Low-cost compact version for volume
production applications. Requires external
coil economizer (PWM or lower hold voltage)
• Patented "hammer effect" mechanism breaks
light contact welds
• Patented "Super-sealed" environment
chamber uniquely protects ALL moving parts
• Can operate in harsh environments
• Moving contact rotates to provide fresh
contact surface for low contact resistance
Fea_at_nu_dre_ls_o:_{w power comsumption}
• Sealed control connector. Mating connector
with flying leads P/N 2005 available, see
page 59
• Logic control enabled by external economizer
P/N 9913
• High temperature (135^oC) model with 10 inch
flying leads available (-4A call factory for
sales drawing)
• Bi-directional power switching
• Fast operate and release time

* Do not apply continously. Requires external coil economizer. Other special coil
voltages available upon request.
* * At maximum continuous current and maximum ambient temperature. Hold
voltage must be maintained within the limits specified to keep contacts closed
and to prevent coil overheating.
* * * Do not use a free wheeling diode or capacitor across the coil.
