• Reduce risk of arc-flash and electrocution, while increasing safety of your personnel
• Decrease maintenance costs and reduce downtime by making critical power quality and energy measurements without opening panel doors, enabling logging and monitoring at any time, without disrupting operations
• Reduce work permit requirements and processes by reducing hazards associated with taking measurements on open panels, saving time and effort
• Increase measurement efficiency and reduce need for arcflash PPE1, saving time, increasing efficiency and increasing operator comfort
• Permanently connected voltage and current sensors located inside electrical panels, allowing you to make power quality and energy measurements using external access points without opening panel doors, thereby 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 need to open cabinet to check clamp models
• Full 360 degree rotation allows PQ400 window to be oriented in any direction
• Simple installation using step drill bit and electro-hydraulic hole punch (114.3 mm, 4.5 inch diameter)
• CAT IV, 600V and CATIII 1,000V rating according to IEC61010-2-30
• Compatibility with standard 4mm shrouded safety-socket voltage test leads makes it easier to make voltage connections, increases safety by reducing risk of accidentally touching live electrical components, and reducing need for purchasing specialized voltage leads
