The Fluke PQ400 Electrical Measurement Window enables the connection of three phase measurement equipment to energized panels, without the need to open the panel door, or wear supplemental personal protective equipment (PPE)1.

The Fluke PQ400 gives you access to the critical power quality and energy data, all while decreasing testing time and helping you to maintain safety.

Reduce the risk of arc-flash and electrocution.

Reduce work permit requirements and processes by reducing the hazards associated with taking measurements on open panels.

Increase measurement efficiency and reduce the need for arc-flash PPE1.

Permanently connected voltage and current sensors located inside the electrical panel 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.

Full 360 degree rotation allows the PQ400 window to be oriented in any direction.

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

Compatibility with standard 4mm shrouded safety-socket voltage makes it easier to make voltage connections.

Dimensions with cover opened: 148 x 19 x 370 mm
