The Megger MMC850 offers a unique solution to current measurement in multi-core cables, without the need to split cables. Simply clamp the MMC850 to a multicore cable and read the current flowing. Conventional current clamp meters have been available for many years and are an accepted method of non-intrusive current measurement. However these instruments can only measure current in a single core cable, requiring multi-core cables to be split before a core can be measured.

Unlike conventional clamp meters, the Megger MMC850 has a complex array of Planer magnetic sensor coils to calculate the current flowing in the conductors of multicore cables with either 2 or 3 cores, and in either flat or round section cable, up to 100 A. The convenience and potential time saving from using the multi-core clamp is considerable. A single button switches the clamp between multi-core and single core operation, ensuring the MMC850 is the only clamp meter you need to carry.

The MMC850 has a tough and lightweight clamp head, allow good access to awkward locations and cables. The inner jaw clamp centralises the cable to be measured ensuring best accuracy. The Megger MMC850 is suitable for supply frequencies from 45Hz to 400Hz. Current measurement to 200 A on single core and 100 A on multi-core cables is possible, with a resolution to 0.1 A, so covering the majority of electrical power applications including Military and Aviation.

The MMC850 multicore clamp meter can also be used in place of traditional clamp meters, when commissioning, or for general maintenance work in electrical machinery and installations.
