PAT410, PAT420 and PAT450 FULL DATABASE DRIVEN PORTABLE APPLIANCE TESTERS

  • Vast on-board memory to keep you the job longer
  • Continuous operation, no need to stop and wait for the tester to cool down
  • Instant re-start as you move from room to room testing
  • Soft keys to speed you through the testing process
  • Full PAT testing including RCD testing
  • Most productive tester in its class

Three new PAT testers with full database functionality based on the well received PAT300 series. The PAT 400 series introduces a new level of convenience and speed to PAT testing using onboard test results.

PAT410 perfect for those content to bond test solely at 200 mA, The smallest, lightest of the PAT400 series weighs only 2.7 kg.

PAT420 offers bond testing at all three currents, 200 mA, 10 A and 25 A and 230 V and 110 V operation. This tester is the choice of those who are full-time industrial or commercial PAT testers.

PAT450 in addition to the three bond test and 230 V and 110 V operation this tester offers 1.5 kV and 3.0 kV flash testing making the perfect tool for hire and repair workshops.

LTW315, LTW325 and LTW335 2 WIRE NON-TRIPPING LOOP IMPEDANCE TESTERS

  • 2 Wire Non-tripping loop tester
  • 50 V to 440 V operation
  • 110 V centre-tap loop testing
  • CATIV installation testing
  • AUTO start – operation
  • 0.01 Ω resolution

The 2 wire non-tripping earth loop testers verify the loop impedance of a live electrical circuit, ie without the need to disconnect the electrical supply. The new LTW300 series instruments offer a 2 wire loop testing solution that does not trip 30 mA RCDs and can be used on a wide range of voltages.

The new LTW300’s offer a range of features to make earth loop testing safer and easier.

The range consists of:

  • LTW315 – 2 Wire loop impedance measurement
  • LTW325 – 2 wire + maxZ + (R1+R2)
  • LTW335 – 2 wire + maxZ + (R1+R2) + Download

LRCD210 and LRCD220 COMBINED LOOP AND RCD TESTERS

  • Non-trip loop tester
  • RCD testing from 10 mA to 1000 mA
  • Extremely easy and safe to use
  • Built-in protective front cover
  • Tough Rubber armoured case
  • Weatherproof
  • 3 year warranty

The Megger LRCD200 series is the latest generation of combined non-tripping loop tester and RCD test instruments that provide simple, affordable and flexible test tools for electrical contractors testing energised circuits.

All LRCD200 series instruments are supplied with a calibration certificate.

Two instruments are available:

LRCD210

This instrument provides three phase safe non-trip loop testing and 1/2I, I, and 5I RCD testing for standard, selective and DC RCDs. Suitable for domestic installers testing to UK Part P requirements.

LRCD220

As the LRCD210 with the addition of 2 wire fast testing, plus phase to phase and phase to earth measurement.

Both instruments will not trip RCDs rated at 30 mA or greater during loop testing, even electronic RCDs.

MEGGER BOOSTS SAFETY IN RCD TESTING

Even if they are inadvertently connected to a live three-phase supply, RCD testers in Megger’s RCDT300 range remain undamaged, and present no safety hazard to the user. Introduced after extensive customer research into the requirements of electrical contractors, these innovative instruments combine rugged construction with straightforward operation, and they are offered at very competitive prices.

Available in three models RCDT300 RCD testers feature a compact design, making them easy to  use, and tough with a rubber overmoulding for additional protection, plus a built-in display cover. All models in the range are water and dust resistant, with an IP54 rating.

RCDT310 model is suitable for use on supplies between 100 V and 280 V, and offers 0.5I, I and 5I tests, with provision for tests starting at 0° or 180° of the supply waveform, as well as for DC tests. It also has facilities for testing standard and selective RCDs, and covers current ranges from 30mA to 500mA. When connected to a live supply, it defaults to voltmeter mode.

RCDT320 covers a wider supply voltage range of 50 V to 280 V, allowing use with centre-tapped 110 V supplies. It incorporates ramp testing, for RCD tripping current measurement, and the unique Megger auto sequence test feature, which saves time by allowing the tester to conduct all the RCD tests, and to store the results while the operator stands by the RCD, resetting it as appropriate.

RCDT320 has an extended operating current range to cover 10 mA to 1,000 mA devices, and the ability to measure AC supply voltage and frequency is added. The large liquid crystal display for test results is backlit in this model, making it easier to use in locations with low ambient light levels.

The RCDT330 additionally offers the facility to save test results to internal memory. Over 1000 result can be saved on site, and downloaded to a computer when convenient.

Data is stored in non-volatile memory, being retained when the instrument is switched off or batteries are exhausted.
