Brochure

The C440 and XT electronic overload relays provide two
levels of communications capabilities—monitoring only,
and monitoring and control—to allow easy integration into
existing plant management systems.
Monitor important
parameters
• Motor status (running,
stopped, tripped, resetting)
• Individual rms phase
currents (A,B,C)
• Average of three-phase
rms current
• Percent thermal capacity
and phase unbalance
• Ground fault current
and percent
• Network “Reset” capability
