The PAC93 AC/DC current clamp from Chauvin Arnoux is a measuring accessory for non-invasive measurement of alternating and direct currents in electrical installations. It is specifically designed for use with various multimeters and power recorders from manufacturers C.A and PEL, and uses the Hall effect for current measurement, enabling both alternating current (AC) and direct current (DC) to be detected. The clamp is designed for use in industrial and technical environments where safe and precise current measurement is required.

Applications
The PAC93 current clamp is suitable for use in electrical installations, for maintenance and servicing of machines, in power distribution, and for monitoring power consumption. It is frequently used in combination with digital multimeters such as models C.A 8331, 8333, 8336, 8436, 8332B, 8334B, 8335, 8435, 8345, 8220 and 8230, as well as with PEL power recorders (e.g. PEL 51/52, PEL 10X/11X). The measurement ranges vary depending on the connected device: for most devices, the AC range is 1 A to 1000 A, while the DC range reaches up to 1300 A. For some models such as C.A 8220/8230, the AC range starts at 10 A, and the DC range ends at 1200 A.

Functions and equipment in detail
The clamp features a clamping diameter of 39 mm, sufficient to enclose single conductors or two conductors each with a diameter of 25 mm. This allows measurement in tight installations or with multiple conductors side by side. The test leads have a length of 3.5 m, providing sufficient reach for use in enclosures or on construction sites.

Technology explained simply
The PAC93 uses the Hall effect, a physical phenomenon in which a magnetic field is generated by an electric current flow. A Hall sensor in the clamp detects this magnetic field and converts it into an electrical signal proportional to the measured current. This enables contactless measurement without interrupting the power supply. The clamp is designed for measuring alternating current (AC) in the range of 1 A to 1000 A and direct current (DC) from 1 A to 1400 A. Measurement accuracy and stability are ensured by Hall technology, which also operates reliably under fluctuating loads.

Compatibility and accessories
The current clamp is compatible with a range of measuring instruments from Chauvin Arnoux (C.A) and PEL. The exact measurement ranges depend on the connected device: models C.A 8331, 8333, 8336, 8436, 8332B, 8334B, 8335, 8435 and 8345 allow an AC range of 1 A to 1000 A and a DC range of 1 A to 1300 A. For models C.A 8220 and 8230, the AC range starts at 10 A and the DC range ends at 1200 A. The clamp is not intended for use with other devices unless compatibility is explicitly stated in the technical specifications.

Installation and mounting
Mounting is done by simply clamping the conductor to be measured with the clamp. The test leads are connected to the respective measuring device. The clamp is suitable for use in enclosures, on construction sites, or in industrial installations. It complies with the safety standard IEC 61010 with category CAT III – 600 V and CAT IV – 300 V, enabling use in electrical installations with the corresponding voltage class. The clamp is therefore suitable for use in industrial electrical engineering and the energy sector.

Advantages in operation
The PAC93 offers fast and safe current measurement without interrupting the power supply. The long operating time of 120 hours with an alkaline battery reduces the need for frequent battery changes. The combination with various measuring instruments expands its range of applications. The robust construction and compliance with safety standards ensure reliable operation in demanding environments. The warranty period is 2 years.
