Surge protector without disconnector ETITEC A 500/10/C-N 002441167

Protection of electrical installations with ETITEC A surge arresters

The ETITEC A 500/10/C-N surge arrester is a key element in protecting low-voltage (LV) networks against the effects of atmospheric and switching surges. This device, manufactured by ETI POLAM, is designed for aerial mounting and effectively protects sensitive electrical equipment from damage.

The lack of a disconnector in this model means that after the surge arrester operates, the circuit is not automatically disconnected – which is important in applications where power continuity is a priority.

Construction and application

ETITEC A surge arresters are characterized by a solid construction and high reliability. Model 500/10/C-N has a piercing single-pole terminal, which facilitates its installation and connection to the network. Using the arrester in an overhead line minimizes the risk of failures caused by sudden voltage increases, protecting both end devices and the installation itself. This is particularly important in areas prone to frequent storms or in places with an unstable power grid.

Key features and benefits

• Effective protection: Protects devices from damage caused by atmospheric and switching surges.
• Design for overhead lines: Designed for outdoor installation, resistant to weather conditions.
• No disconnector: Maintains power continuity after the arrester operates – an ideal solution for critical applications.
• Piercing single-pole terminal: Facilitates quick and safe installation.
• ETITEC A series: Guarantee of high quality and reliability from the renowned manufacturer ETI POLAM.
• Rated voltage 500V: Adapted to low-voltage networks with standard voltage.
• Impulse current 10kA: Provides effective protection against sudden current surges.
• Protection class C: Indicates that the arrester reacts quickly to overvoltages, but allows for short-term overloads without disconnecting the circuit – useful when starting devices with electric motors.

The ETITEC A 500/10/C-N surge arrester is an investment in the safety and reliability of the electrical installation, which translates into minimizing repair costs and downtime related to failures caused by surges.
