L (Long-time protection)
S (Short-time protection with fixed time delay)
I (Instantaneous protection)
ZSI (Zone Selective Interlocking)

L - Protection against overload -- adjustable 0.3...1 x In (70A...250A)
S - Protection against short-circuit with time delay -- adjustable 1.5...10 x Ir (105A...2500A)
I - Instantaneous protection against short-circuit -- adjustable 1.5...12 x In (375A...3000A)

Current measurements
- Phases (I1 / I2 / I3) and neutral (IN) RMS instantaneous current
- Phases (I1 / I2 / I3) average current Iavg = (I1 + I2 + I3) / 3
- Current unbalance between phases as a % of Iavg
- Highest RMS current of the 3 phases Imax = max (I1 + I2 + I3)
- Ground fault current R as a % of ground fault protection pick-up setting Ig
- Demand/peak current values on all 3 phases + neutral (Present value on the selected window + Maximum demand since last reset). Calculation window adjustable 5-60min.

Voltage measurements
- Phase-to-phase voltages (VAB / VBC / VCA)
- Average of phase-to-phase voltages Uavg = (VAB + VAC + VBC) / 3
- Ph-Ph voltage unbalance as a % of Uavg
- Phase-to-neutral voltages (UAN / UBN / UCN)
- Average of phase-to-neutral voltages Vavg = (UAN + UBN + UCN) / 3
- Ph-Ph and Ph-N voltage unbalance as a % of Vavg
- Phase sequence 1=>2=>3 / 1=>3=>2

Power measurements
- Active (kW) power per phase + total
- Reactive (kVAR) power per phase + total
- Apparent (kVA) power per phase + total
- Demand/peak power values (kW / kVAr / kVA) (Present value on the selected window + Maximum demand since last reset). Present value on the selected window. Maximum demand since last reset.
- Power factor PF and cos phi per phase + total

Energy metering
- Active (kWh) energy per phase + total (absolute or signed mode)
- Reactive (kVARh) energy per phase + total (absolute or signed mode)
- Apparent (kVAh) energy per phase + total (absolute or signed mode)

Power quality and harmonic analysis
- THDu (Total Harmonic Distortion on phase-to-phase voltages)
- THDv (Total Harmonic Distortion on phase-to-neutral voltages)
- THDi (Total Harmonic Distortion on phase currents)
