Fluke Current Clamp, 400A Maximum AC Current, 32mm Maximum Conductor Size - I400S
This current clamp is a Compact AC current probe designed to extend the measurement range of oscilloscopes, power analysers and multimeters in industrial environments. It measures alternating current without interrupting conductors and includes a soft non‑slippery overmould handle for safer handling during field and workshop work. Its construction supports use across typical site temperatures and comes with a BNC connector for instrument interfacing.
Features & Benefits
• Measures up to 400 A ac while maintaining usable accuracy
• Two output sensitivities for flexible signal scaling
• Safety rated CAT IV 600V and CAT III 1000V for high‑voltage sites
• 2.5m output cable for convenient instrument placement
• Accepts conductors to 32mm diameter for single‑conductor measurements
• Compact form factor for access in confined panels
• Two output sensitivities for flexible signal scaling
• Safety rated CAT IV 600V and CAT III 1000V for high‑voltage sites
• 2.5m output cable for convenient instrument placement
• Accepts conductors to 32mm diameter for single‑conductor measurements
• Compact form factor for access in confined panels
**Applications**
• Suitable for verifying load currents on industrial automation racks
• Ideal for waveform capture with portable oscilloscopes
• Used with power quality analysers for site energy diagnostics
• Can be used for commissioning and fault‑finding on distribution boards
• Used with DMMs when paired with the optional BNC/banana adaptor

What output signals will my measuring device receive?
The probe provides two output levels depending on range: 10 mV per amp in the low range and 1 mV per amp in the high range to match different instrument input sensitivities.
How does the probe perform across frequency ranges?
The device maintains usable response from low mains frequencies up to 10 kHz, allowing accurate capture of harmonic and transient components within that bandwidth.
What accuracy can I expect at lower currents?
On the lower range the accuracy is specified as 2% Plus 0.015 A for the frequency band noted, providing consistent readings for small to moderate currents.
Are there environmental limits for operation on site?
The unit is rated to operate between 0 °C and 50 °C, permitting use in typical indoor and sheltered outdoor conditions.
What connector and accessory options support multimeter connection?
It terminates in a BNC connector and can be adapted for direct DMM banana inputs using the optional BNC/banana adaptor.
