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
Features:
moving 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
