Voltage presence indicator - lamp (1 x red LED) SON H-1R 002471550

Voltage presence indicator – reliable signaling

This voltage indicator, also known as a signaling lamp, is a simple yet extremely useful device. It is used to visually check for the presence of voltage in an electrical circuit. Its main task is to inform whether voltage is present, which is particularly important during maintenance, repairs and testing of electrical installations. This increases work safety and minimizes the risk of accidental electric shock.

Construction and application

The SON H-1R indicator is a modular lamp with a red LED, designed for mounting in electrical distribution boards or control cabinets. Powered by 230V AC, it signals the presence of voltage in the network. Its compact dimensions (18 x 70 x 86 mm) allow for easy installation even in tight spaces. The IP20 protection class provides basic protection against touch and dust - sufficient for most applications inside buildings.

In practice, it finds application wherever quick and clear information about the voltage status is needed:

• Distribution boards: Monitoring the power supply of individual circuits.
• Control cabinets: Signaling the operating status of devices.
• Workshops and service centers: Safe voltage check before starting work.
• Home installations: Indicating the presence of voltage in sockets or lighting circuits (although this is not its primary purpose).

Key features and benefits

• Clear signaling: The red LED provides good visibility even in low light conditions.
• Simple installation: The device is designed for quick mounting on a TH35 rail or directly to the housing.
• Reliability: The product from the ETI POLAM brand guarantees solid construction and long life.
• Safety: Visual voltage control minimizes the risk of electric shock during service work.
• Versatility: Can be used in various types of 230V AC electrical installations.
• Compact dimensions: Allow for installation in limited space without problems with access to other installation elements.
