Feature Features

  • Measures and displays current; protects against over current, undercurrent, and current asymmetry.
  • Options:
    • Adjustable min and max current and alarm threshold
    • Adjustable delayed start for heavy motors
    • Built-in alarm for error warning
    • Two separate relays for ALARM and TRIP
  • Ten indicators:
    • AC: grid electricity
    • Alarm Relay: alarm relay mode
    • Trip Relay: trip relay mode
