Surge protector with disconnector ETITEC A 280/5/E-NO 002441104

Surge protection in electrical installation

The ETITEC A 280/5/E-NO surge limiter is a reliable element protecting the electrical installation from the effects of sudden voltage increases. It is a device designed to protect overhead lines, and its operation is based on varistor technology. Using a surge limiter minimizes the risk of damage to connected devices and ensures continuity of power supply.

Construction and application

This limiter is designed to operate in TN, TN-C and TN-S network systems. Its construction allows for direct mounting, which simplifies and speeds up installation. Protection class II / C according to IEC/VDE provides effective protection against surges of 0.9kV. The device is particularly useful in places exposed to frequent voltage changes, such as areas with an unstable power grid or near sources of electromagnetic interference.

Key features and benefits

• High efficiency: Rated discharge current of 5kA (8/20μs) and the ability to withstand short-circuit current of 4kA guarantee effective protection against surges.
• Fast response: Varistor technology ensures a lightning-fast response to sudden voltage increases, minimizing the duration of disturbances.
• Versatility: Possibility of use in various network systems (TN, TN-C, TN-S) increases the scope of application of the limiter.
• Visual signaling: Optical indication of device operation informs about the need to check the limiter status after a surge occurs.
• Operating voltage: Continuous operating voltage Uc is 280V, and the rated AC voltage is 230V, making it suitable for standard electrical installations.
• Leakage current: It has a leakage current, which is important for ensuring safe use.
• Compliance with standards: Meets the requirements of IEC/VDE standards, which confirms its quality and safety.

The ETITEC A 280/5/E-NO limiter is a solid and effective solution for anyone who cares about the safety of their electrical installation and protects their devices from damage caused by surges. It is an investment in peace of mind and the reliability of the power system.
