Material Composition
Flame-retardant thermoplastic enclosure with precision current transformers and industrial-grade relays.
Structural Characteristics
Compact DIN-rail or panel-mount design with front-panel LCD display, navigation buttons, and LED status indicators.
Working Principle
Continuously samples motor current and voltage, processes the data through embedded algorithms, and compares values against programmed setpoints to initiate protective actions.
Installation Requirements
Mount on standard DIN rail or panel. Wire CTs and control circuits according to the wiring diagram. Provide adequate ventilation.
Usage Precautions
Verify CT ratios match motor full-load amps. Set protection parameters according to motor nameplate data. Test trip functions before commissioning.
