Increase the safety and speed of setting up power quality and energy analyzers, and logger with Fluke PQ400 Electrical Measurement Windows. Reduce the risk of arc-flash and electrocution, increase the safety of your personnel and reduce the time and cost of preventive maintenance.

Permanently connected voltage and current sensors are located inside the electrical panel, which allow you to make power quality and energy measurements using the external access points without opening the panel door, reducing operator risk. Voltage and current connections for three-phase voltages, neutral and ground cover most measurement scenarios. 

Automatic probe detection for Fluke 1740 and 1730 series power quality and energy loggers and compatible clamps, eliminates the need to open cabinet to check the clamp model.  Compatibility with standard 4 mm shrouded safety-socket voltage test leads makes it easier to make voltage connections, increases safety by reducing the risk of accidently touching live electrical components, and reduces the need for purchasing specialized voltage leads.

Kit includes the PQ400 enclosure, 4 (four) male-male cable 2M for connection of Fluke 17xx iFlex current probes, cable marker set 3P + N + PE, cable ties, and instruction sheet.  The basic version does not include cables, cable ties, or markers.

• No more opening the panel door for installation of loggers and analyzers 

• Full 360° rotation allows the PQ400 window to be oriented in any direction 

• Work permit requirements and NFPA 70E processes are significantly reduced 

• Supplemental arc-flash PPE is often not required so inspections are done faster and more comfortably

• Simple installation using only a step drill bit and electro-hydraulic hole punch

• CAT IV, 600V and CATIII 1,000V rating according to IEC61010-2-30
