Comprehensive motor protection plus voltage dependant
overload curves, torque metering and protection, broken
rotor bar protection
• Most advanced thermal model – Including multiple RTD
inputs for stator thermal protection
• Minimize replacement time – Draw-out construction
• Complete asset monitoring – Temperature, Analog I/O, full
metering including demand & energy
• Improve uptime of auxiliary equipment – Through I/O
monitoring
• Reduce troubleshooting time and maintenance costs –
Event reports, waveform capture, data logger
• Built in simulation functions simplify testing and
commissioning
• Cost Effective Access to information – Through standard
RS232 & RS485 serial ports, and optional Ethernet and
DeviceNet Ports
• Field upgradable firmware and settings
• Optional Conformal coating for exposure to chemically
corrosive or humid environments
• Protection and Management of three phase medium and large horsepower motors and

Protection and Control
