General
Maximum voltage	300 V
Tip diameter	2 mm

Removable test probes for test leads in the CAT II 300 V range, manufactured by Chauvin Arnoux. These insulated test probes are specifically designed for use in residential areas and low-voltage applications. They serve as safe connection elements between test leads and measurement objects, with complete insulation of the tips providing an enhanced safety level. The tips have a diameter of 2 mm, enabling precise contact at small connection points. The socket has a diameter of 4 mm and allows for a secure connection with compatible test leads.

Applications
The test probes are intended for applications where the risk of electric shock is considered low. This includes work on devices connected to grounded sockets, as well as measurements in electronics, telecommunications, and systems whose power source is separated from the public power grid. The CAT II 300 V category specifies that the probes are suitable for low-voltage installations that are not directly connected to the main supply, but are powered via an intermediate stage such as a socket or distributor.

Functions and Equipment in Detail
The test probes are fully insulated, meaning that the metallic parts are covered with an insulating material except for the actual tip. This protects the user from unintended contact with conductive parts. The red and black color coding allows for easy distinction between positive and negative poles, which is helpful when performing measurements. The tips are removable, allowing them to be replaced or cleaned as needed.

Technology Explained Simply
The protection category CAT II 300 V refers to the maximum voltage that the test probes can safely transmit. This category is intended for installations that are not directly connected to the main power supply, but are powered via an intermediate stage such as a socket or distributor. The maximum voltage of 300 V is sufficient for typical residential and small-scale applications. The PVC insulation provides high insulation effectiveness and protects against electrical contact. The 2 mm diameter tip enables precise and secure contact, while the 4 mm socket ensures a stable connection with the test leads.

Compatibility and Accessories
The test probes are designed for use with compatible test leads that also meet the CAT II 300 V protection category. They are not suitable for higher voltage categories such as CAT III or CAT IV. Use with measuring instruments not designed for CAT II is not recommended. The test probes are supplied in a set of two units (red and black).

Mounting and Installation
The test probes are inserted into the ends of test leads, with the socket of the probe fitting into the corresponding connector of the lead. The connection is tool-free and mechanically stable. The removable design allows for easy replacement of the tips in case of wear or contamination.

Advantages in Operation
The complete insulation of the test probes increases safety when working with electrical installations. The precise 2 mm diameter tip enables secure and reliable contact, even at small connection points. The color coding simplifies polarity identification. The removability of the tips offers flexibility for maintenance and cleaning. The test probes are particularly suitable for use in residential areas and low-voltage applications, where the risk of electric shock is considered low.
