MN SERIES

Product catalog summary

Overview: The MN Series current clamps are designed for measuring AC currents from 0.01 A to 240 A. These ergonomic mini-clamps are suitable for low and medium current measurements and are compatible with all multimeters and testers. They feature jaws that can grip conductors up to 20 mm in diameter, ideal for restricted access areas.

Types and Output: There are two types of MN series clamps: one functions as a current transformer with a 1000/1 ratio, providing a current output in mA, and the other provides a voltage output proportional to the measured current, allowing for measurements even with testers lacking current calibres.

Electrical Specifications: The clamps have a current range of 0.5 A to 240 A AC, with a transformation ratio of 1000/1. The output signal varies by model, with options for 1 mA AC/A AC or voltage outputs like 10 mV AC/A AC. Accuracy improves with higher currents, and the phase shift is minimal. The bandwidth is 40 Hz to 10 kHz, and the clamps can handle a crest factor of 3 for 200 A RMS.

Mechanical Specifications: The clamps operate between -10 °C and +55 °C and can be stored from -40 °C to +70 °C. They are designed to withstand drops from 1 meter and have a shock resistance of 100 g. The casing is rated IP40, and the clamps are made from self-extinguishing materials.

Safety and Compliance: The MN series clamps comply with IEC 1010-1 & IEC 1010-2-032 standards, ensuring double or reinforced insulation. They are rated for 600 V category III and 300 V category IV environments. Electromagnetic compatibility is ensured as per EN 50081-1 and EN 50082-2 standards.

Models and Ordering: Specific models like MN08, MN09, MN10, MN11, MN12, MN13, MN14, MN15, and MN21 are available, each with unique specifications and output configurations. Each model comes with an operating manual for ease of use.

Specifications Overview:

Electrical Specifications: Various models of AC current clamps have different current ranges and output signals. The accuracy of the output signal varies with the primary current, and the bandwidth is consistent across models at 40 Hz to 10 kHz. The crest factor and maximum currents are specified, with a common mode voltage of 600 V category III.
Mechanical Specifications: Operating temperature ranges from -10 °C to +55 °C, with storage temperatures from -40 °C to +70 °C. The clamps have a maximum jaw opening of 20 mm and a clamping capacity for cables and busbars. The casing protection rating is IP40, and the clamps are designed to withstand drops, shocks, and vibrations.
Safety Specifications: The clamps feature double or reinforced insulation as per IEC standards, suitable for 600 V category III and 300 V category IV environments. They comply with electromagnetic compatibility standards, including resistance to electrostatic discharge and radiated fields.

Key Features and Applications:

The clamps are designed for measuring current on transformer secondary circuits and have a wide measurement range, making them versatile for various applications.
Models MN88 and MN89 provide a DC voltage output, beneficial for multimeters with low sensitivity.

Ordering Information:

Each model comes with an operating manual, and specific references are provided for ordering.

Catalog excerpts

Current clamps for AC current Pinces ampèremetriques pour courant AC MN SERIES These ergonomic mini-clamps are designed to make light work of measuring low and medium currents from 0.01 A to 240 A AC. The shape of the jaws makes ‘hooking’ onto cables easy, even in areas of restrictive access. The jaws can grip conductors up to 20 mm in diameter. Depending on the particular model, they have one or two calibres. The output is via either jack sockets or a lead with 4 mm Ø plugs, hence these clamps are compatible with all multimeters and testers on the market. There are two types of MN series clamps available. The ﬁrst kind operates as a current transformer (ratio 1,000/1) and gives a current output (mA) for use with any tester with current calibres. Non-contractual document The second type gives a voltage output (DC or AC depending on the model) proportional to the measured current (1, 10, 100 or 1,000 mV/A). This voltage output means that, even with testers without any current calibres, it is possible to measure currents by means of the DC or AC voltage calibres. There are speciﬁc models in the MN series that have been designed with particular applications in mind such as measurement on current transformer outputs, on oscilloscopes and even of leakage currents.
