Surge arrester without disconnector ETITEC A 280/5/DK-N 002442743

Protection of electrical installations with ETITEC surge limiters

The ETITEC A 280/5/DK-N surge limiter is a protective device designed to protect electrical equipment from the effects of atmospheric and switching surges. It is a key component in any installation where high reliability and safety are required. Its operation is based on quickly discharging excess energy to ground, minimizing the risk of damage to connected receivers.

This limiter is used in building installations, both residential and commercial, as well as in industrial facilities. It works particularly well in places exposed to frequent lightning strikes or in installations powering sensitive electronic devices.

• Fast response to surges: Provides almost instantaneous protection against sudden voltage spikes.
• High energy discharge capacity: The discharge current Imax is 5kA (8/20µs), which allows for effective protection against strong surges.
• Rated voltage: Operates in 230/400 V networks with a frequency of 50 Hz, making it compatible with most standard electrical installations in Poland.
• Continuous operating voltage (Uc): 280 V AC – adapted to protect devices sensitive to surges with a lower rated voltage.
• Protection class: II – provides additional safety by isolating from the housing.

The limiter's construction is based on technology that guarantees its long-lasting and reliable operation. Installation is simple and intuitive, making it easy to integrate with an existing electrical installation. It is important to select the limiter correctly for the specifics of the installation being protected and to follow safety precautions during installation and operation. ETITEC limiters are characterized by high quality workmanship and meet applicable safety standards.
