Key Protection Features
- Real-Time Amperage Readout: High-visibility digital LED window alternates current draw metrics for active lines, simplifying balancing diagnostics.
- Microprocessor-Driven Accuracy: Eliminates the variance of traditional bimetallic thermal overloads, maintaining tight trip windows despite ambient panel temperatures.
- Adjustable Delay Timers: Features independent settings for starting delay (D-Time) and overcurrent operating trip delay (O-Time) to prevent nuisance tripping from standard motor inrush spikes.
- Pass-Through CT Windows: Integral current transformer holes accept direct passage of main load lines, eliminating extra terminal contact resistances and heating points.
