Surge protector without disconnector ETITEC A 280/5/CK-N 002442742

Surge protection in electrical installations

The ETITEC A 280/5/CK-N surge arrester is a protective element designed to protect electrical devices from the effects of sudden voltage increases. It is a key component in any installation where power stability is important – both in residential and industrial buildings. This device effectively minimizes the risk of damage caused by lightning strikes or other disturbances in the power grid.

This arrester is characterized by high efficiency and durability. Its construction based on varistors ensures a quick response to surges, dissipating excess energy to ground and protecting connected devices. The continuous operating voltage of 280V makes it particularly well suited for 230/400V networks commonly used in Poland.

Key features and application

• Rated voltage: 230 / 400 V 50 Hz – ensures compatibility with most electrical installations.
• Continuous operating voltage (Uc): 280 V AC – optimal for standard power grids.
• Rated discharge current (In): 5 kA – indicates the ability to dissipate significant energy during a surge. This means that these arresters are effective even with strong voltage impulses.
• Maximum discharge current (Imax): 40 kA – determines the maximum current value that the arresters can withstand without damage.
• Protection level (Up): ≤ 900 V – guarantees that the voltage on the receiver side does not exceed a safe level even during a surge.
• Protection class: II - provides additional safety.

The ETITEC A 280/5/CK-N surge arrester is used wherever there is a need to protect sensitive electronic devices from surges. It is ideal for protecting:

• electrical installations in residential and public buildings,
• RTV and household appliances,
• alarm and fire protection systems,
• LED lighting,
• computer equipment and servers.

Installing a surge arrester is an investment in the safety and reliability of the electrical installation, which can protect against costly failures and downtime. Choosing ETITEC A 280/5/CK-N guarantees effective protection of your devices.
