Key Features:
- Advanced thermal model-based protection including overload curves, negative sequence unbalance/single phase offset, RTD offset for hot/cold motor compensation, and motor cooling time constant
- Comprehensive protection functions: stall, mechanical lockout, ground overcurrent, short circuit, differential protection, and voltage-related protection (overvoltage, undervoltage, phase reversal, overfrequency, underfrequency)
- 12 RTD inputs for stator, bearing, and ambient temperature monitoring
- Integrated power metering, event recording for up to 40 recent events, and waveform capture for troubleshooting
- Drawer-style design for quick replacement, with support for RS232, RS485, optional Ethernet and DeviceNet communication ports
- Field-upgradable firmware and settings, with optional conformal coating for corrosive or humid environments
Applications:
- Protection and management of medium and large horsepower three-phase motors, including high-inertia, two-speed, and reduced-voltage start motors
- Industrial automation systems, power generation facilities, oil and gas operations, and water treatment plants
