I. Product Positioning
The Fluke professional AC leakage current clamp meter, featuring Fluke Connect Bluetooth wireless (the “FC” suffix indicates the wireless version), is designed for non-stop detection of weak leakage currents. It is suitable for industrial control, power plants, high and low voltage cabinets, frequency converters, and motor insulation checks. The 61mm ultra-wide shielded jaw can hold multi-core cables, grounding copper bars, and thick power cables.
Core Hardware Parameters
Current Measurement (AC only)
Range: 3mA ~ 60A, 6 automatic switching levels (3mA/30mA/300mA/3A/30A/60A)
Maximum Resolution: 1μA (3mA range, capable of capturing micro-amp level minor leakage)
Frequency Range: Filter enabled: 40–70Hz (power frequency noise reduction); Filter disabled: 40Hz–1kHz (measuring variable frequency harmonics)
True RMS: Compatible with frequency converters, servo systems, rectifiers, non-sinusoidal waveforms of non-sinusoidal waveforms
Waveform Factor: 3
Accuracy (filter enabled, calibrated within 1 year)
3mA ~ 30A: ±1.5% reading + 5 digits
60A range: ±2% reading + 5 digits
Jaw and Anti-interference
Opening Diameter: 61mm (compared to 40mm of 368FC, suitable for thick cables, simultaneous measurement of multiple phase lines)
Full Shielded Jaw, significantly suppressing on-site EMI electromagnetic interference, ensuring that weak leakage currents are not drowned by noise
Safety Protection
CAT III 600V / CAT IV 300V industrial safety level, suitable for high and low voltage distribution site
Storage and Wireless (FC exclusive)
Local Storage: 65,000 sets of measurement data, capable of long-term continuous recording of leakage current trends
Fluke Connect Bluetooth Wireless: Connect to mobile phone APP, real-time reading, curve export, generating inspection reports, cloud archiving, and sharing data among multiple users
Body and Power Supply
Size: 116×257×46mm; Weight 600g
Power Supply: 2 AA 5-volt batteries, no backlighting, battery life approximately 150 hours without backlighting
Companion: Backlit LCD, front LED cabinet lighting, reading hold / maximum minimum average value recording, automatic shutdown (15 minutes of no operation)
Core Functions
Non-stop measurement of residual leakage current
No need to disconnect or dismantle wires, simply clamp the entire cable (L+N+PE) to directly measure the total residual leakage current, locating insulation aging, cable cracking, frequency converter ground leakage, and RCD frequent tripping root causes.
Power Frequency Noise Filtering
When enabled, filters out harmonic waves from frequency converters, accurately reading the true insulation leakage at 50/60Hz; when disabled, it can measure high-frequency leakage currents of variable frequency equipment.
Trend Recording
Long-term continuous sampling to capture intermittent leakage (hidden faults that occur after equipment heating).
Wireless Data Management
Synchronous measurement at the site with a mobile phone, eliminating the need for manual recording, suitable for preventive inspections and archiving of power plant and industrial control equipment.
Typical Application Scenarios (Suitable for your industrial control / excitation / distribution industry)
Generator excitation cabinet, grounding leakage detection of low-voltage auxiliary cabinets
ABB ACS6000, AC800PEC drive frequency converter ground leakage detection
Medium-voltage cabinets, cable trays, motor stator insulation leakage inspection
Factory RCD / leakage protection device false tripping fault location
