Surge protector without disconnector ETITEC A 280/5/TK-N 002442747

Protection of electrical installations and devices

The ETITEC A 280/5/TK-N surge protector is a protective element designed to protect electrical installations and connected devices from the effects of atmospheric and induced overvoltages. This is crucial for ensuring the continuity of systems and avoiding costly failures.

Construction and application

This surge protector, designed to operate in 230/400V networks at a frequency of 50Hz, is characterized by a continuous operating voltage of 280V AC. Its construction is based on protection class II, which provides additional safety. It finds application in protecting electrical circuits in residential, commercial and industrial buildings. Thanks to its design, it effectively dissipates surge energy to ground, minimizing the risk of damage to sensitive electronic components.

Key features and benefits

• High protection efficiency: Maximum discharge current Imax of 5kA (8/20µs) guarantees effective protection against sudden voltage surges.
• Wide voltage range: The surge protector is adapted to work with a rated voltage of 230/400V AC, making it a universal solution for various installations.
• Safety of use: Protection class II provides protective insulation, minimizing the risk of electric shock.
• Durable construction: Made of high-quality materials ensures reliable operation for a long time.
• Overvoltage limitation: Provides effective protection against atmospheric overvoltages (lightning strikes) and induced overvoltages (e.g. switching on and off large loads).
• Protection voltage: ≤ 900V – surge protectors of this type only start to operate when this value is exceeded, which minimizes the risk of false alarms and unnecessary circuit tripping.
