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 (U12 / U23 / U31)
- Average of phase-to-phase voltages Uavg = (U12 + U21 + U23) / 3
- Ph-Ph voltage unbalance as a % of Uavg
- Phase-to-neutral voltages (V1N / V2N / V3N)
- Average of phase-to-neutral voltages Vavg = (V1N + V2N + V3N) / 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)

ComPacT NSX
Moulded-Case Circuit Breakers and Switch-Disconnectors from 16 to 630A - up to 690V
Meet the new face of connected breaker technology.

The Schneider Electric ComPacT range is built on 70 years of expertise and leadership in industrial circuit breakers.
Today Schneider Electric is launching its new generation of ComPacT molded case circuit breakers.
The comprehensive‚ optimized ComPacT range covers your protection and has been redesigned with a superior customer experience in mind.
The range combines wireless intelligent metering and monitoring‚ along with advanced protective functions

This range can be connected to Schneider Electric's open‚ interoperable‚ IoT-enabled EcoStruxureTM Power architecture.
Through this platform we deliver enhanced value in terms of safety‚ reliability‚ efficiency‚ sustainability‚ and connectivity.
We leverage technologies in IoT‚ mobility‚ sensing‚ cloud‚ analytics‚ and cybersecurity to deliver Innovation at Every Level. This includes connected products‚ edge control‚ apps‚ analytics and services.

ComPacT Design
New Signature Design
- Schneider Electric green signature style for the entire ComPacT range
- Estimated 40% reduction of wiring time for panel builders
- Experience easier installation thanks to a new ergonomic front-plate design
- Gain the confidence that all auxiliaries are on the right spot‚ and simply double check that you have the right coil rating
- Ergonomic new toggle for easier breaker manual operation

Wireless Breaker Status
Wireless technology accelerates overall wiring timeː Status communication is done very simply and commissioned wirelessly. No cable connection is required‚ with a simple clip‚ the auxiliary is installed and ready for commissioning.
In case of a change on your breaker's status‚ you get two steps of indicationː
- Remote indication (App/Software)ː Your ComPacT circuit breaker will send you an immediate notification via your Edge Control app/software.
- Local indication (Blinking LED)ː Gain time by identifying which breaker is concerned in your overall electrical architecture

Smallest size in the range
- ComPacT NSXm is the smallest frame size in the range‚ incorporating new features and innovations
- Gain up to 40% in space when using with integrated earth leakage protection
- Reduce up to 40% mounting and cabling time with EverLink connectors‚ built-in DIN rail and spring-type auxiliaries
- Select‚ configure and commission with ease‚ thanks to Schneider Electric online toolsː EcoStruxure Customer Lifecycle Software‚ such as EcoStruxure Power Design - Ecodial

Integrated earth leakage protection
- Easy to integrate into a row that does not have earth leakage protection
- Simple to use‚ reliable‚ and now comes in the same frame size‚ and for the same panel support
- Gain up to 40% in space when using with integrated earth leakage protection into the MicroLogic Vigitrip units
- Standard protection of distribution cables
- Part of the EcoStruxure Power architecture‚ with digital communication capability and data management (settings‚ measurement‚ pre-alarms‚ trip & test history)

Roto-activeTM breaking technology
EverLink connectors - for enduring protection
While the ComPacT NSXm is the smallest breaker in the ComPacT range‚ it nonetheless features all the innovations from previous generations‚ and notably includes roto-active breaking technology.
Schneider Electric was the first to introduce this technology - an innovation in which the effective fault current limitation benefits the entire installation‚ particularly its cables.
Reduce the effects of short circuits to extend your installation lifeː
- Increase life duration of all items downstream of the electrical network
- Provide both outstanding selectivity and cascading
