TECHNICAL DATA

Fluke PQ400 Electrical

Measurement Window

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)

Compliance without compromise. Safety without

sacrifice.

The Fluke PQ400 gives you access to the critical power quality and

energy data you need, all while decreasing testing time and help-

ing you to maintain safety.

• Reduce the risk of arc-flash and electrocution, while increasing

the safety of your personnel

• Decrease maintenance costs and reduce downtime by making

critical power quality and energy measurements without

opening the panel door, enabling logging and monitoring at any

time—without disrupting operations

• Reduce work permit requirements and processes by reducing

the hazards associated with taking measurements on open

panels, saving time and effort

• Increase measurement efficiency and reduce the need for arc-

flash PPE, saving time, increasing efficiency and increasing

operator comfort

Features

• 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 (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 the risk of accidently touching live

electrical components, and reduces the need for purchasing

specialized voltage leads

REDUCED RISK

Permanently installed voltage and

current connections can be accessed

without opening the panel door

INCREASED EFFICIENCY

Quickly connect your logger

or analyzer and begin taking

measurements faster than ever

EASY INSTALLATION

A standard step drill bit and

electro-hydraulic hole punch

provide the simple means to quickly

mount the window in the panel

Comply with local and national safety codes. Use personal protective equipment

(approved rubber gloves, face protection, and ﬂame-resistant clothes) to prevent shock

and arc blast injury where hazardous live conductors are exposed.
