Victor Clamp Leaker – High-Precision AC Leakage Current Clamp Meter Range UP to 300A 140

$62.99

The Clamp Leaker 140 is a purpose‑built AC leakage current clamp meter that combines high sensitivity (10µA resolution) with a wide 300A capacity, enabling electricians, maintenance engineers, and safety inspectors to measure everything from parasitic leakage on medical equipment to full load current on feeders. Its clamp CT, integral method ensures accurate readings even in noisy electrical environments, while the 35×40mm jaw accommodates thick grounding conductors or bundled cables. With 99‑group data storage, peak hold, auto‑ranging, and automatic frequency recognition (50/60Hz), the Clamp Leaker reduces manual steps and logging errors. Safety is paramount: CAT III 600V, double insulation, and 2kV dielectric strength make it suitable for live testing on circuits up to 600V. Lightweight (200g) and compact, it operates for hours on two AAA batteries and automatically powers off after 5 minutes. Whether you work in electricity, oil fields, railway, scientific research, or industrial maintenance, the Clamp Leaker delivers laboratory‑grade leakage detection in a rugged, field‑ready tool.

The Clamp Leaker is not just another clamp meter—it is a dedicated AC leakage current clamp meter engineered for safety professionals, electrical maintenance teams, and field service technicians who need to detect problems others overlook

1. Microamp‑Level Leakage Detection

The Clamp Leaker starts measuring from 0.00mA with an outstanding 10µA resolution, making it capable of capturing leakage currents as low as a few microamps. This sensitivity allows early detection of insulation degradation, moisture ingress, or hidden grounding faults—issues that ordinary clamp meters (typically 0.1A resolution) miss entirely. With the Clamp Leaker, you can prevent unexpected tripping, electric shocks, and fire hazards before they occur.

2. Wide Dynamic Range: From Leakage to Full Load

Unlike dedicated leakage testers that max out at a few amps, the Clamp Leaker covers 0.00mA to 300.0A in a single device. This means you can use it for both sensitive leakage measurements on grounding conductors and full load current checks on feeders, motors, or HVAC equipment. The Clamp Leaker eliminates the need to carry separate meters—one tool, full spectrum.

3. Dual‑Zone Accuracy for Reliable Readings

  • 0–60A: ±1.5% rdg ±5dgt
  • 60A–300A: ±2% rdg ±5dgt

The Clamp Leaker delivers laboratory‑grade accuracy across its entire range. The low‑end precision ensures you can trust leakage readings near safety thresholds (e.g., 30mA RCD trip levels), while the high‑end performance remains solid for heavy‑load verification.

4. True CT + Digital Integration Method

Many low‑cost meters use averaging detection, which fails on distorted or non‑sinusoidal currents. The Clamp Leaker employs a clamp CT, integral method—the same technology used in precision power analyzers. This ensures accurate measurement of true RMS leakage current even in circuits polluted by harmonics, VFDs, or switching power supplies.

5. Generous Jaw Size, Minimal Instrument Footprint

The Clamp Leaker features a 35 × 40mm jaw that easily accommodates thick grounding cables, busbars, or bundled conductors. Yet the whole instrument measures only 180 × 72 × 32mm and weighs just 200g (including batteries). You can slip the Clamp Leaker into a tool pouch or laptop bag and carry it all day without fatigue.

6. Automatic Frequency Recognition (50Hz / 60Hz)

No need to manually select line frequency. The Clamp Leaker automatically detects whether you are working on 50Hz or 60Hz systems—ideal for technicians who service equipment across regions or mixed industrial sites.

7. Peak Hold for Inrush & Intermittent Leakage

Long‑press the hold button, and the Clamp Leaker continuously displays the peak value without releasing. This is critical for capturing:

  • Motor inrush currents
  • Intermittent leakage spikes from insulation breakdown
  • Short‑duration events that normal sampling (2 times/second) might miss

A short press gives you standard data retention with a clear "DH" symbol on the LCD.

8. 99‑Group Internal Data Storage

The Clamp Leaker stores up to 99 measurement groups internally—no need for a notepad or smartphone. Perfect for:

  • Periodic leakage trend logging
  • Comparing before/after repairs
  • Documenting compliance with safety standards

You can recall stored data directly on the 4‑digit LCD display.

9. Overflow & Low Battery Warnings

  • "OL" display clearly indicates when the measured current exceeds 300.0A, preventing misinterpretation.
  • A dedicated low battery warning activates when voltage drops below 2.8V, ensuring you never trust a reading from a dying Clamp Leaker.

10. Safe for Live Work (CAT III 600V)

The Clamp Leaker is safety‑rated per IEC1010‑1, IEC1010‑2‑032, Pollution degree 2, CAT III 600V. It also withstands AC 2kV/rms insulation strength between the iron core and housing. You can confidently test circuits up to 600V AC in distribution panels, switchgear, and industrial control cabinets without risk.

11. Automatic Power‑Off (5 Minutes)

Forget about draining batteries. The Clamp Leaker shuts itself down after 5 minutes of inactivity. With a typical working current of only 5mA and powered by two standard AAA batteries, a single set lasts for months of regular field use.

12. Rugged Environmental Tolerance

  • Operating: 0°C to 40°C, <80% RH
  • Storage: -10°C to 60°C, <70% RH

The Clamp Leaker performs reliably in damp basements, outdoor substations, and hot industrial plants—and survives storage in truck toolboxes or unheated warehouses.
