Equipped with an integrated disconnector, this device effectively protects electrical installations from transient overvoltages, ensuring safety and reliability in industrial and residential power networks.

## Long description

The Apator ASA 440-5BO+E2+K is a professional-grade surge arrester engineered to safeguard electrical installations against transient overvoltages. Designed for reliability, this device acts as a critical barrier in power distribution systems, effectively diverting excess energy caused by atmospheric discharges or switching operations to prevent damage to sensitive equipment. With its robust construction and integrated disconnector, it provides a dependable solution for maintaining the integrity of electrical networks in both residential and industrial environments.
Advantages
This surge arrester offers superior protection by reacting rapidly to voltage spikes, thereby extending the lifespan of connected electrical appliances and infrastructure. The inclusion of an integrated disconnector ensures that the device can safely isolate itself from the circuit in the event of a failure, preventing potential fire hazards or short circuits. Its compact design allows for easy installation within standard electrical panels, while the high-quality materials used in its manufacturing guarantee long-term performance and stability under varying operational conditions.
Suitable for
Residential electrical distribution boards
Industrial automation control panels
Protection of sensitive electronic devices
General power supply networks
When it may not be suitable
This device is not intended for use in high-voltage transmission lines or systems exceeding its rated voltage capacity of 440V. It should not be used as a primary lightning protection system for buildings without additional external lightning protection measures.
Key specifications
Rated voltage: 440V
Discharge current capacity: 5kA
Integrated disconnector: Yes
Application: Overvoltage protection
How to use
The surge arrester should be installed by a qualified electrician in accordance with local electrical codes and safety regulations. It is typically mounted on a standard DIN rail within the main distribution board, connected in parallel with the load to be protected. Ensure that the grounding connection is secure and has low impedance to allow for effective dissipation of surge energy. The device should be positioned as close as possible to the incoming power supply for maximum efficiency.
What to consider before purchase
Verify that the rated voltage of your electrical system does not exceed 440V.
Ensure there is sufficient space in your distribution board for installation.
Check that the discharge capacity meets the requirements of your specific application.
Confirm that the device is compatible with your existing grounding system.
Usage recommendations
Regularly inspect the status indicator of the surge arrester to ensure it remains operational. If the disconnector has been triggered, the device must be replaced immediately to restore protection to the electrical system.
