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
  • Delay Start: delayed initial start (3-300 sec)
  • CT: display and adjust CT (5–1000A)
  • Delay Off: delayed disconnect (2–60 sec)
  • Unbalance: current asymmetry (10–100% CT)
  • Max: max current (0.01A–120% CT)
  • Alarm: alarm current (0­­–120% CT)
  • Min: min current (0–120% CT)

Note: indicators blink when in adjustment mode.

• Terminal wiring and installation manuals

Note: initial start time is the time after starting during which no current increase factors in.
