Surge protector without disconnector ETITEC A 500/10/SK-N 002442729

Protection of electrical installations and devices

The ETITEC A 500/10/SK-N surge protector is a safety device designed to protect electrical installations and connected devices from the effects of overvoltage. This is particularly important in places exposed to lightning strikes or voltage fluctuations in the network. The design without a disconnector makes it a discreet and easy-to-install solution.

Construction and application

This surge protector uses a varistor as a voltage limiting element. A varistor is a resistor whose resistance changes depending on the voltage – at normal voltage it has high resistance, and during overvoltage its resistance drops sharply, dissipating excess energy to ground. This protects sensitive devices from damage.

The surge protector is designed to operate at a rated voltage of 500 V AC 50 Hz and is intended for alternating current installations. A key element of its operation is the varistor, which provides a quick response to overvoltage and effectively limits its value.

Installation and benefits of use

Installation of the ETITEC A 500/10/SK-N surge protector is simple and does not require specialized tools. Installation should be performed by a qualified electrician in accordance with applicable standards and regulations. Using this type of protection translates to:

• Increased safety: protection against damage to equipment and potential fire hazards caused by overvoltage.
• Reduced repair costs: reducing the risk of failure and the need to replace expensive electronic devices.
• Long-term protection: the varistor provides multiple responses to overvoltage, protecting the installation for a long time.
• Discreet installation: the lack of a disconnector makes it easier to integrate with the existing electrical installation without unnecessarily increasing its size.
