General
Enclosure diameter	20 mm

The current clamp MN73A from Chauvin Arnoux is a specially developed accessory for the installation tester C.A 6133. It is designed for precise measurement of alternating currents in electrical installations and extends the functionality of the test device by enabling current measurements in the range of 10 mA to 200 A AC. The clamp is designed for use in low-voltage installations and allows contactless current measurement, thereby increasing the safety of the operator.

Applications
The clamp is primarily used in the field of electrical installation and electrical safety testing. It is suitable for measuring leakage currents, operating currents, and other alternating current components in electrical systems. The clamp is used in conjunction with the installation tester C.A 6133, which displays and evaluates the measured values. The application typically occurs during commissioning, maintenance, or testing of electrical installations.

Functions and Equipment in Detail
The current clamp MN73A features a jaw opening diameter of 20 mm, allowing it to encircle conductors with a diameter up to 20 mm. This value is sufficient for measurements in typical low-voltage installations, as most conductors fall within this size range. The clamp is designed as a 2-range ammeter clamp, covering two measurement ranges: 2 A and 200 A. Measurements are taken in the alternating current (AC) range, which is relevant for most applications in electrical installation. The clamp is equipped with a 4-pole connector, ensuring a secure and reliable connection to the test device C.A 6133.

Technology Explained Simply
The clamp operates on the principle of a current clamp, where a magnetic field generated by the current to be measured induces a signal in a measuring coil system. This induced signal is converted into an electrical signal and transmitted to the test device. The measurement is performed without direct contact with the conductor, increasing safety. The clamp is designed for alternating current measurements, with a range of 10 mA to 200 A AC covering most applications in electrical installation. The accuracy of the measurement depends on the quality of the clamp and correct handling.

Compatibility and Accessories
The clamp is intended exclusively for use with the installation tester C.A 6133. Compatibility is ensured by the 4-pole connector, specifically developed for this device. The clamp is offered as a replacement part or addition to the C.A 6133 to extend its functionality.

Mounting and Installation
Mounting of the clamp is done by simply connecting it to the installation tester C.A 6133 via the 4-pole connector. The clamp is closed around the conductor to be measured, taking into account the jaw opening diameter of 20 mm. The measurement is then performed directly on the device. No additional tools or mounting procedures are required. Operation is performed via the test device, which displays the measured values.

Advantages in Operation
The clamp enables fast and safe current measurement without direct contact with the conductor. Integration with the installation tester C.A 6133 allows direct display and evaluation of measured values. Measuring leakage currents and operating currents is particularly important for safety testing of electrical installations. The clamp is robust and designed for use in the trade, with measurement accuracy and reliability being the main focus. The user manual, included in the delivery, supports correct handling and use of the clamp.
