Leakage current clamps BENNING CM 9-2

SKU: BENNING CM 9-2 Categories: ,

Product description

Error-related leakage currents are caused by weak insulation or insulation damages. The BENNING CM 9-1/ CM 9-2 allows quick and precise localization of all error types. By means of preventive measurements, possible damages due to uncontrolled leakage currents can be avoided in advance.

Common features:

  • measurement of leakage currents and differential currents in electrical systems (VDE 0100/0105), devices (EN 50678, EN 50699) and machines (EN 60204-1/ VDE 0113-1)
  • DIN EN 61557-13 defines requirements for “current clamps for measuring leakage currents in electrical installations”, e. g. protection against external magnetic fields: class 2, magnetic field ≤ 30 A/m; frequency range: min. 40 Hz to 3rd harmonic of the mains frequency (150 Hz), recommended use: railway (as of 15 Hz), industry (up to 1 kHz)
  • DIN EN 61557-16 (requirements for appliance testers) defines filters with fg = 1 kHz for measuring protective conductor currents IPE in electrical and medical electrical devices
  • precise due to TRUE RMS measuring method
  • reliable and easy detection of insulation faults (e.g. defective cables, loose terminals, contamination, moisture)
  • measurement without switch-off during normal operation of the system/ device
  • ideal for preventive maintenance and fault localization (protection against damages and personal injury, blackouts etc.)
  • precise and reproducible measuring results up to 60 A AC

BENNING CM 9-2 with Bluetooth® function and App:

  • Bluetooth® Low Energy 4.0 interface
  • IOS and Android app for viewing, storing and sharing measured values via smartphone/tablet
  • Low-pass filter (50 Hz – 60 Hz) for rejection of high frequency interference signals
  • memory of measured value (HOLD) and maximum/minimum value (MAX/MIN)
  • incl. carrying case and batteries

Perfectly complemented by

Intermediate adapters are required for current measurement and for correct contacting for differential current measurement, direct protective conductor current measurement or load current measurement

  • measuring adapters with individual lines led through for current measurements on CEE equipment
    • three-phase, 16 A/ 400 V CEE plug/ coupling (044127)
    • three-phase, 32 A/ 400 V CEE plug/ coupling (044128)
    • single-phase, shock-proof plug/coupling (044131)
