Voltage presence indicator with button (3 x red LED) SON-3 ZP 002471410

Voltage presence indicator – a reliable network status indicator

This voltage indicator with a button, catalog number 002471410, is a practical solution for both professional installers and end users. It is used to visually check the presence of voltage in single-phase and three-phase networks. Equipped with three red LEDs, it clearly indicates the status of each phase, and an additional button allows for quick verification of voltage presence.

Construction and application

The SON-3 ZP indicator is designed for mounting on a TH35 rail. Its construction based on self-extinguishing plastic ensures safe use. Thanks to its compact size (1 module wide), it can be easily integrated with the existing electrical installation. The indicator is particularly useful in distribution boards, control panels and anywhere where continuous voltage status monitoring is required. In the event of a phase failure, the corresponding LED goes out or dims, allowing for quick identification of the problem.

Key features and benefits

• Polyphase: Monitoring the status of three phases (3x400/230 V AC) allows for comprehensive network diagnostics.
• Built-in test button: Enables immediate verification of the indicator's operation and voltage presence.
• Clear LED indication: Three red LEDs provide clear information about the status of each phase even in low light conditions.
• Mounting on TH35 rail: Standard mounting simplifies integration with existing electrical infrastructure.
• Safety: Housing made of self-extinguishing plastic (UL94-V0) minimizes the risk of fire spreading.
• Wide voltage range: Adapted to operate in networks with a rated voltage of 400V AC with a tolerance of -25% +10%.
• Protection class IP20: Provides protection against touching with a finger and protects against larger solid bodies, which is sufficient for most applications inside buildings.
• Compliance with standards: Meets the requirements of IEC EN 61000-3-2; IEC EN 61000-4-2; IEC EN 61000-4-3; IEC EN 61000-4-4; IEC EN 61000-4-5; IEC EN 61000-4-6; IEC EN 61000-4-1, which confirms its high quality and reliability.

Thanks to these features, the SON-3 ZP indicator is a reliable tool for monitoring the status of the electrical network, helping to quickly detect faults and prevent more serious failures. It is a product of ETI Polam, a renowned manufacturer of high-quality electrical equipment.
