Two-pole voltage indicator P-4 WMGBP4

Two-pole voltage indicator – a reliable tool for professionals and demanding users

This two-pole voltage indicator from Sonel, model P-4 (WMGBP4), is a versatile device designed for safe and quick checking of voltage presence, circuit continuity and phase rotation direction. Designed for work in difficult conditions, both in industrial and domestic installations, it combines solid construction with intuitive operation.

Functionality and safety in one device

The P-4 indicator offers a wide range of functions that make it indispensable during electrical work:

• Non-contact voltage detection: Allows for safe checking of voltage presence without direct contact with wires.
• Two-pole voltage measurement: Enables precise determination of voltage value in the range of 12…690 V.
• Circuit continuity indicator: Quickly and easily checks if the circuit is conductive.
• RCD testing: Allows verification of the correct operation of residual current devices.
• Single-pole phase indication: Facilitates identification of the phase in the electrical installation.
• Safety category CAT III: Provides a high level of user protection when working with electrical installations.
• Illuminated measurement point: Enables work in low-light conditions.

Construction and application

The P-4 voltage indicator is characterized by a durable construction and IP65 protection class, which guarantees resistance to dust and moisture. It is an ideal tool for:

• Electricians and installers: For daily work related to the installation, maintenance and repair of electrical equipment.
• Service technicians: For quick diagnosis of problems with electrical installations.
• Home users: For safely checking the condition of the electrical installation in the home (with caution and knowledge).

The device is powered by a battery (accumulator), which ensures mobility and ease of use. The lack of a backlit LCD display does not affect its functionality in typical working conditions, and the illuminated measurement point effectively copes with insufficient lighting. It is worth remembering the CAT III measurement category, which defines the range of safe use of the device in different types of electrical installations.
