Acti9 iMX-230/400 surge protection device 100415 VAC, 110130 VDC A9A26476

Surge protection in electrical installations

The Acti9 iMX-230/400 surge arrester (A9A26476) is an element protecting the electrical installation against the harmful effects of voltage surges. The device, manufactured by Schneider Electric, is designed to work with iC60, iID, iDPN Vigi, iSW-NA series circuit breakers and others from the Acti9 family. Its task is to quickly react to exceeding the permissible voltage values, minimizing the risk of damage to connected devices.

Functionality and application

This surge arrester monitors voltage in the range of 100-415 VAC and 110-130 VDC. This ensures protection in both single-phase and three-phase installations. Mounted on a DIN rail, it occupies only one module width, allowing for optimal use of space in the distribution board. Its main task is to disconnect the circuit in the event of a dangerous voltage surge, protecting sensitive electronic devices from damage. This is particularly important in places exposed to atmospheric overvoltages or network disturbances.

Key features and benefits

• Wide voltage range: Compatible with AC and DC installations with a voltage of 100 to 415 V, ensuring versatility of application.
• Compact size: Occupies only one module on the DIN rail, making it easy to install even in crowded distribution boards.
• Compatibility with the Acti9 series: Ensures full compatibility with Acti9 circuit breakers and residual current devices, creating a comprehensive protection system.
• Fast reaction: Immediate disconnection of the circuit in the event of a surge minimizes the risk of damage to connected devices.
• Simple installation: Easy installation on a DIN rail without the need for additional tools.
• Increased safety: Protects electrical devices from damage caused by surges, extending their lifespan and minimizing repair costs.
• Up to 63A main contact current: Allows use in circuits with higher load.
