Megger RCDT300 RCD testers for electricians
Tests standard, DC and selective RCDs • Ramp testing • Auto (Remote) testing • 3 Phase safe • Enables testing on 110 V centre tapped supplies. • Tough rubber armoured case with built-in cover • Weatherproof to IP54
MEGGER BOOSTS SAFETY IN RCD TESTING
Even if they are inadvertently connected to a live three-phase supply, RCD testers in Megger’s new 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, ensuring that all users can choose a model which exactly meets their needs, RCDT300 RCD testers feature a compact ergonomic design, making them easy to handle and use, and a tough impact-resistant body 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 ingress protection rating.
The low-cost entry-level RCDT310 model is suitable for use on supplies between 100V and 280V, and offers 0.5I, I and 5I tests, with provision for tests starting at 0ْ/180ْ 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.
The mid-range RCDT320 covers a wider supply voltage range of 50V to 290V, allowing use with centre-tapped 110V supplies. It incorporates ramp testing 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.
The operating current range of the RCDT320 is extended to cover 10mA to 1,000mA 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. A Job reference number can be selected for a range of results, allowing separate locations to be tested with the same tester and easily separated when downloaded.
A memory bar graph acts as a ‘Fuel Gauge’ showing how much memory has been used. Test results are downloaded to CSV (Coma Separated Variable) spreadsheets.
If certificates or reports are required, the results can be downloaded directly into Megger Powersuite Professional with a range of features for creating professionally finished documentation.
All models in the range comply fully with the requirements of IEC61010-1 for Category III 300V applications, and are supplied complete with appropriate test leads and a calibration certificate.

MEGGER BT51 Low Resistance
Ohmmeter
High test current
Four terminal measurement
Two measuring ranges (2000 mΩ. and 20,00 mΩ.)and
maximum resolution of 0,01 mΩ.
Protected against inadvertent connection to the
mains supply
The BT51 Low Resistance Ohmmeter makes measurements
by passing a current through the conductor under test and also monitoring the
voltage across it. The test current is limited by a simple current limiting
circuit and is measured by monitoring the voltage across a resistor. The test
current is maintained at a nominal 2 A, and as the measurement is ratiometric,
the reading is unaffected by any current variations.
• Gives quick check of insulation tester
calibration • Contains high quality resistors • Calibration certificate
provided
The CB101 is a calibration box suitable for
checking the accuracy of insulation testers. Four resistors are connected in the
unit to enable a wide range of values to be checked. The high quality resistors,
rated to high voltage, can be used to check resistance readings with test
voltages up to 5 kV d.c. A calibration certificate is provided with each CB101
showing the actual value of each resistance checkpoint.
