Voltage presence indicator - lamp (3 x red LED) SON H-3R 002471552

Voltage presence indicator – reliable signaling in the installation

This voltage indicator, also known as the SON H-3R modular lamp, is a simple but extremely useful device for visually checking the presence of voltage in a circuit. It is ideal for both home and industrial installations, where quick and easy phase identification is crucial. Three red LEDs provide clear and readable signaling, even in low light conditions.

Functionality and application

The SON H-3R indicator is designed for mounting on a TH35 rail. Its main task is to inform about the presence of voltage in individual phases of the circuit. Thanks to this, installers can quickly and safely verify the correctness of connections, and end users can be sure that the electrical installation is working properly. Signaling with three LEDs makes it easier to identify phases – particularly useful during maintenance or repair work.

Characteristic features and benefits

• Clear signaling: Three bright, red LEDs provide excellent visibility even from a distance.
• Universal power supply: Designed to operate with 230V AC voltage – standard voltage in most electrical installations.
• Safety: Allows for quick and safe verification of voltage presence before starting work.
• Mounting on TH35 rail: Standard mounting simplifies integration with existing electrical infrastructure.
• Durability: Made of high-quality materials, which guarantees long life and reliable operation.
• IP20 protection class: Provides basic protection against accidental contact and the ingress of solid objects larger than 12.5 mm.

It is worth remembering that this indicator does not replace professional voltage meters, but constitutes an additional safety element and facilitates quick diagnosis of the electrical installation status. Its simple construction and ease of installation make it an ideal solution for both experienced installers and demanding end users.
