Surge protector without disconnector ETITEC A 500/10/CK-N 002442838

Protection of electrical installations and devices

The ETITEC A 500/10/CK-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 an electronic component whose resistance changes depending on the applied voltage. Under normal operating conditions, the varistor has high resistance, minimizing its impact on the circuit. When an overvoltage occurs, the varistor's resistance drops sharply, directing excess energy to ground and protecting connected devices.

• Rated voltage of 500V AC (50 Hz) makes it suitable for protecting devices with a similar rated voltage.
• Designed for use in single-phase installations (A-N).
• Application inside buildings – protection against overvoltages resulting from induction or direct lightning strikes.
• Ideal for protecting sensitive electronic devices such as audio-video equipment, computers or home automation systems.

Installation and benefits for the installer

Installation of the ETITEC A 500/10/CK-N surge protector is simple and intuitive, which translates into time savings during installation. The lack of a disconnector simplifies installation and reduces the number of elements needed to perform a correct installation. Additionally:

• Compact dimensions allow for mounting in a limited space of the switchboard.
• Provides effective protection against overvoltages – in accordance with safety standards.
• Solid construction guarantees long-lasting and reliable operation of the device.
• Fast reaction to overvoltages minimizes the risk of damage to connected devices.
