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
• Internal coil economizer provides:
− 4W typical hold power independent
of temperature & voltage range
− EMI spectrum tested and approved
− Built-in coil suppression
• Patented "hammer effect" mechanism breaks
light contact welds
• Patented hermetically "Super-sealed"
environment chamber uniquely protects ALL
moving parts
F_• ea_Ct_au_nre_os_p: _{erate in harsh environments}
• Moving contact rotates to provide fresh
contact surface for low contact resistance
and low power comsumption
• Sealed control connector. Mating connector
with flying leads P/N 2005 available, see
page 59
• Special versions available:
− Economical (-8A/B) for light duty
power switching (without arc blowout
magnets
− 10 inch flying leads model (-7A)
