Surge arrester without disconnector ETITEC A 500/10/A-N 002441165

Power supply protection – surge arresters ETITEC A

The ETITEC A 500/10/A-N surge arrester is a safety element protecting electrical installations from the effects of atmospheric and switching surges. Designed for use in low-voltage overhead lines, it effectively protects electrical devices from damage caused by sudden voltage increases. This model, without a disconnector, is dedicated to bare lines, meaning it does not have a built-in disconnecting mechanism in case of exceeding permissible values. This is an ideal solution for installations requiring continuous power supply, where protection against damage is a priority, not automatic circuit disconnection.

Construction and application

The ETITEC A 500/10/A-N arrester belongs to the ETI POLAM series of surge arresters, valued for their reliability and high efficiency. Its construction is based on metal-oxide varistors (MOV), which are characterized by a fast response time and high energy absorption capacity. Using this type of arrester minimizes the risk of failures and downtime in power systems, which translates into savings and increased safety of use. This is particularly important in places exposed to frequent lightning strikes or in installations powering sensitive electronic devices.

Key features and benefits

• Effective protection: Protects electrical devices from damage caused by atmospheric and switching surges.
• Intended for bare lines: Construction adapted to the specifics of overhead lines without insulation.
• No disconnector: Ensures continuous power supply – no automatic circuit disconnection in case of voltage exceeding. This is important in critical applications where a power interruption is unacceptable.
• High energy absorption capacity: MOV varistors effectively suppress surges, protecting connected devices.
• Reliability: ETI POLAM arresters are known for their high quality and long service life.
• Mounting: Designed for mounting on low-voltage overhead lines – requires appropriate qualifications and adherence to safety regulations during installation.

The ETITEC A 500/10/A-N surge arrester is an investment in the safety and reliability of your electrical installation. By choosing this product, you gain confidence in protection against the effects of unforeseen events and minimize the risk of costly failures.
