Surge arrester without disconnector ETITEC A 660/10/C-N 002441177

Surge protector – protection of installations and devices

The ETITEC A 660/10/C-N surge protector is a key element in protecting electrical installations from the effects of sudden voltage increases. The device effectively protects against damage caused by lightning strikes or other network disturbances, minimizing the risk of failures and downtime. The use of varistor technology ensures a quick and effective response to surges.

Construction and application

The surge protector is designed to protect overhead lines in TN, TN-C and TN-S network systems. Its construction based on varistor technology guarantees high efficiency in suppressing surges. The nominal discharge current of 10kA (8/20μs) and the ability to withstand short-circuit current of 4kA testify to its solidity and reliability. The device has a protection level Up of 2.05kV, which ensures effective protection of sensitive electrical equipment. Direct mounting facilitates integration with existing infrastructure.

Key features and benefits

• Effective protection: Protects the circuit against overload and short circuit - like most circuit breakers in this class.
• Varistor technology: Provides a quick response to surges, minimizing the duration of disturbances.
• Versatile application: Designed for TN, TN-C and TN-S systems, which increases its versatility.
• High durability: Nominal discharge current of 10kA (8/20μs) and short-circuit withstand capacity of 4kA guarantee reliable operation in difficult conditions.
• Optical indication of operation: Allows quick identification of the device status and the need for replacement after a surge occurs.
• Leakage current: Has a leakage current function, which further increases safety.
• Class C: The Class C surge protector allows it to react more slowly to short current spikes, so it tolerates starting devices with a motor well.
• Operating voltage Uc 660V: Adapted to work in installations with a voltage of up to 660V AC.

The ETITEC A 660/10/C-N surge protector is an investment in the safety and reliability of the electrical installation, which translates into minimizing costs associated with failures and downtime.
