Features:
• 400 A carry, 2,500 A interrupt @ 320 Vdc
• Hydrogen dielectric for power switching high
current loads
• Internal Hall Effect contact position sensor
detects contact welds
• Ideal for circuit protection, control, battery
switching, and main power safety disconnect
• Versatile power, voltage, and current
operating range: 28-1800Vdc switch tested
• Internal economizer provides:
− 4W typical hold power independent
of temperature & voltage variance
− EMI spectrum tested and approved
• Patented "hammer effect"
mechanism breaks light contact welds
• Patented hermetically "Super-sealed"
environment chamber uniquely protects ALL
Fea_mt_ou_vre_ins_g: _parts
• Can operate in harsh environments
• Moving contact rotates to provide fresh
contact surface for low contact resistance
and low power consumption
• Sealed control connector. Mating connector
with flying leads P/N 2625 available, see
page 59
• Bi-directional power switching
• Fast operate and release time
• Low power consumption
• Auxiliary contacts
