Chauvin Arnoux P01295458Z Test probes 4 mm / 4 mm socket CAT II 300 V PVC red+black content_copy

Removable test probes from the brand Chauvin Arnoux, specifically designed for applications in category CAT II and below, serve as accessories for test leads in electrical measurements at low voltages. These test probes are intended for use in residential environments as well as in areas such as electronics and telecommunications, where the risk of electric shock is low. They are suitable for work on devices connected to earthed sockets, as well as on installations whose power source is separated from the public distribution network. The probes are available in a set of two units, one red and one black, and feature a 4-mm plug connection compatible with corresponding test leads.

Test probes are designed as removable components, enabling flexible use and easy cleaning. The connection is made via a 4-mm socket, commonly used in many test leads and multimeters. The color coding (red/black) supports correct assignment during measurements and conforms to standard conventions in electrical engineering. The probes are PVC-coated, providing mechanical stability and some protection against external influences.

Applications include primarily residential environments, where electrical devices are operated from earthed sockets, as well as applications in electronics and telecommunications where voltage is below 300 V. The test probes are not suitable for work in higher voltage categories (such as CAT III or CAT IV), as they are certified only for CAT II installations. The limitation to 300 V ensures an adequate safety margin for the specified applications.

Functions and equipment in detail include the use of two removable probes, each equipped with a 4-mm socket. The color coding (red and black) serves to distinguish between positive and negative poles during measurements. The PVC coating provides mechanical protection and improves handling. The probes are not intended for use in explosive environments or under extreme environmental conditions.

Technology explained simply shows that the test probes function as a mechanical interface between the measuring device and the object under test. The 4-mm plug connection is a standard in measurement technology, ensuring a secure and reproducible connection. The CAT II approval means that the probes are suitable for electrical installations in residential environments, where voltage is up to 300 V and the risk of electric shock is reduced by earthing and protective measures. The PVC coating protects the metallic parts and prevents unintended contact.

Compatibility and accessories include use with test leads that also feature a 4-mm plug connection. The test probes are not intended for use with devices requiring a different plug connection (e.g., 2.5 mm or 4 mm with a different shape).

Mounting and installation is done by simply inserting the test probes into the corresponding sockets of the test leads. No additional tools or mounting procedures are required. The connection is mechanically stable and can be released by pulling out the probes.

Operational advantages lie in easy handling, clear color coding, and removability, which allows for cleaning and replacement. Use in combination with suitable test leads ensures safe and reliable measurement at low voltages in residential environments and similar applications. The test probes are not intended for use in industrial or high-voltage environments.

The test probes are available in a set of two units (red and black).
