Electronic phase loss and rotation monitoring
relays for three-phase applications
• Universal voltage monitoring (U
N
from 208V to
480V, 50/60Hz)
• Phase loss monitoring, even under phase
regeneration
• Positive safety logic - Make contact opens if the
relay detects an error
• 2 versions:
• 1 CO relay output, 6A (17.5mm wide), and
2 CO relay output, 8A (22.5mm wide)
• 35mm rail (EN60715) mount
• European patent pending for the innovative
principle at the root of the 3 phase monitoring
and error survey system (70.61)
