Surge protector with disconnector ETITEC A 280/10/E-NO 002441144

Installation and device safety – surge protection

The ETITEC A 280/10/E-NO surge arrester is a key element of any electrical installation, providing protection against the effects of sudden voltage spikes. The device effectively protects connected devices from damage caused by atmospheric surges or network disturbances. Its construction based on varistor technology guarantees a fast response and effective limitation of the voltage to a safe level.

Construction and application

The arrester is designed to protect overhead lines in TN, TN-C and TN-S systems. Its compact size allows for direct mounting, and the optical indication of operation allows for quick identification of a situation where intervention has occurred. Protection class II / C confirms its effectiveness in protecting installations against overvoltage. The device is single-pole and designed to operate with a voltage of 280V AC.

Key features and benefits

• High efficiency: Rated discharge current of 10kA (8/20μs) and the ability to withstand short-circuit current of 4kA guarantee reliable protection even with strong surges.
• Varistor technology: Ensures a fast response to voltage spikes, minimizing the risk of damage to connected devices.
• Versatile application: Compatible with various network systems (TN, TN-C, TN-S), making it a universal solution for many installations.
• Optical indication: Facilitates identification of the moment the arrester operates, allowing for quick diagnosis of the problem and taking appropriate action.
• Direct mounting: Simplified mounting saves time and installation costs.
• Compliance with standards: Meets IEC/VDE requirements, confirming its safety and reliability.
• Leakage current: Has a leakage current function, which increases safety.
• Continuous operating voltage Uc: 280V AC - adapted to standard electrical installations.
