BENNING CM 9-1

Common features:

Measurement of leakage, residual and protective conductor currents in electrical systems (DIN VDE 0100/ 0105), devices (VDE 0701, VDE 0702) and machines (DIN VDE 0113-1), DGUV regulation 3

DIN EN 61557-13 defines requirements for "Current clamps for measuring leakage currents in electrical installations" e.g. protection against external magnetic fields: Quality class 2, magnetic field ≤ 30 A/m; frequency range: min. 40 Hz - 3rd harmonic of the mains frequency (150 Hz), recommended applications: railway (from 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 appliances

Precise due to TRUE RMS AC measurement method

Reliable and simple detection of insulation faults (e.g. defective cables, loose terminals, dirt, moisture)

Measurement without switching off during normal operation of the system/device

Ideal for preventive maintenance and troubleshooting (protection against property damage and personal injury, power failures, etc.)

Precise and reproducible measurement results up to 60 A AC

BENNING CM 9-1 with multimeter functions:
