Fluke PQ400/B Basic Electrical Measurement Window

Features and Specifications

• Voltage and current connections for three-phase voltages, neutral and ground cover most measurement scenarios
• Quickly connect your logger or analyzer and begin taking measurements with voltage and current sensors located inside the electrical panel
• Make power quality and energy measurements using the external access points without opening the panel door, reducing operator risk
• Full 360 degree rotation allows the PQ400 window to be oriented in any direction
• Automatic probe detection for Fluke 1740 and 1730 series power quality and energy loggers and compatible clamps
• CAT IV, 600V and CATIII 1,000V rating according to IEC61010-2-30
• Compatibile with standard 4mm shrouded safety-socket voltage test reduces the need for purchasing specialized voltage leads leads

General Specifications

• 1000 V Maximum voltage between any voltage terminal and earth ground
• 30 V Maximum voltage between any current terminal and earth ground
• Enclosure: UL 50/NEMA environmental type 1 (Type 12 when PQ400 cover is closed)
• Number of inputs: 5 (A/L1, B/L2, C/L3, N, and earth/ground)
• Input Voltage: Max. 1000 V
• Output Load current: Max. 1 A rms
• Connectors: 5x 4-pin circular compatible with Fluke 354x FC, 173x, and 174x power and energy loggers (these loggers can all be powered from the measured voltage up to 500V)

The Fluke PQ400 Electrical Measurement Window is a permanently installed interface designed to provide technicians with quick access to electrical panels for conducting critical power quality and energy measurements. Installation of the PQ400 involves using a standard step drill bit and an electro-hydraulic hole punch (with a hole diameter of 114.3 mm or 4.5 inches). This window allows users to establish three-phase voltage, current, and ground connections, covering a wide range of measurement scenarios. Once installed, technicians can easily unlock the window cover, lift the lid, and connect the voltage leads of their logger or analyzer. Subsequently, they can attach the leads for the current sensors and begin making essential measurements. After completing the measurements, they can simply disconnect the voltage and current connections from the front panel interface and lock the window lid, leaving the internal connections intact for future use.
