Description

The Megger MIT400 series insulation and continuity testers have been designed for electrical testing by power utilities, industrials, telecommunication companies, commercial/domestic electricians and anyone with unique test voltage requirements. The wide range of features also makes the MIT400 series ideal for maintenance technicians and engineers. They replace the well-established BM400 insulation tester range, giving greater functionality with simplified operation, greater application range and increased safety. The MIT400 Series instruments are designed to meet all of the requirements of IEC1010-2 and EN61557 and meets the safety requirements for use on CAT IV 600 V. Also, fast detection circuitry prevents damage to the instruments if accidentally connected to live circuits or across phases. Specific safety features include:

  • Any live circuit detection inhibits any insulation testing on circuits above 50 V (75 volts on Telecom models)
  • Any live circuit detection and test inhibit on continuity measurements
  • Default display of live circuit voltage on all ranges
  • Detection and inhibit features function even if the protections fuse has failed

The MIT Models 410, 420 and 430 add additional features required for technicians and engineers working on more demanding applications. Functions such as PI and DAR, capacitance measurement and a higher insulation range increase the functionablity.

Applications for the Megger 430 CAT IV insulation tester:

  • Building/Campus electrical maintenance
  • Large and small scale electrical installations
  • Periodic electrical systems inspection and testing
  • Cable testing
  • Plant maintenance and production testing
  • Panelboard testing
  • Railway and other transportation maintenance and testing
  • Motor testing
  • Cable inspection/quality control
  • Street lighting maintenance
  • Avionics ground testing and maintenance
  • Military hardware and facility maintenance

The Megger 430 ships complete with:

  • Set of silicone test leads – Flexible and long lasting, these leads prevent errors from test lead leakage on high resistance type of insulation testing. They also provide increased accuracy above 10 GΩ
  • Rugged instrument rubber boot with built-in stand– Protects the instrument from dings and drops and provides an easier, better grip of the instrument.
  • Plug-in switch probe – Allows the user to remotely perform insulation tests, reducing the time taken to perform a test. Not included with the MIT400 and 40X.
  • High-impact polypropylene carry case – Further protects the instrument and provides space for the leads, switch probe, etc.
  • Free calibration certificate (not included with the MIT40X).
  • Owner information CD.
  • Three year product warranty.
