Leakage current clamps BENNING CM 9-1 and CM 9-2

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 9-1 with multimeter functions:

• universally applicable for current measurements (60 A AC), voltage measurements (600 V), resistance measurements (600 kΩ) and continuity tests
• Low-pass filter (40 Hz - 70 Hz) for rejection of high frequency interference signals
• memory of measured value (HOLD) and peak value storage
• incl. carrying case, measuring leads and batteries

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
