These test probes are specifically designed for voltage testers of the models C.A 745N, C.A 755, and C.A 757. They serve as replacement or additional probes for electrical measurements in industrial and building technology applications. The probes are designed for use in electrical installations that meet the safety requirements of categories CAT III and CAT IV, making them suitable for measurements in complex and potentially hazardous environments. The construction ensures a reliable and safe connection between the measuring device and the test object, enabling precise voltage measurements.

Test probes are the central component of this product and consist of a set of two individual parts, each equipped with a 4 mm pin plug. This plug connection is standardized and enables a secure and mechanically stable connection with the specified voltage testers. The probes are designed for a maximum operating voltage of 1000 V, making them suitable for measurements in high-voltage installations within the low-voltage technology sector. The color coding is red and black, which corresponds to the usual conventions for phase and neutral conductors in electrical engineering and facilitates identification during the measurement process.

Safety category is a decisive aspect when selecting measurement accessories. The test probes comply with the CAT III and CAT IV standards, meaning they are designed for measurements in electrical installations with high transient overvoltages. CAT III applies to installations in the distribution technology sector, such as in buildings or industrial facilities, while CAT IV is the highest category for measurements at the energy supply level, for example at meter connection points. This classification protects the user from dangerous electrical discharges and is a prerequisite for use in professional environments.

Application is in the fields of industrial and building technology, where precise and safe voltage measurements are required. The test probes are directly connected to the measuring devices C.A 745N, C.A 755, and C.A 757 to check the voltage on electrical conductors, switches, sockets, or other components. Their use is particularly important during maintenance work, installations, or safety inspections, where the reliability of measurement results and the safety of the operator are paramount.

Compatibility is limited to the specified voltage testers: C.A 745N, C.A 755, and C.A 757. The test probes are not intended for other devices or models, as the plug connection and electrical specifications are specifically matched to these devices. Using them with other measuring instruments may result in incorrect readings or safety hazards. Therefore, the probes are a direct replacement or supplement for the mentioned devices.

Scope of delivery includes the test probes themselves, consisting of two individual parts (red and black), as well as an instruction manual for safe use. The manual contains guidance on correct handling, compliance with safety regulations, and avoiding errors during measurement. The manual is written in German and serves as a reference for the user.

Operational advantages lie in the high safety class, the mechanical stability of the plug connection, and the clear color coding. The test probes enable quick and safe measurements without additional adapters or conversions. Compliance with CAT III/IV standards ensures that measurements can be carried out safely even under demanding conditions. Their use in conjunction with the specified voltage testers creates a consistent and reliable measurement chain, which is required in professional applications.
