Product information

Description

The Apator ASA 440-5BO+E3+K is a professional-grade surge arrester engineered to provide robust protection for electrical installations operating at a rated voltage of 440V. With a discharge current capacity of 5kA, this device effectively diverts transient overvoltages to the ground, preventing potential damage to sensitive electronic components and electrical infrastructure. The inclusion of an integrated disconnector ensures that the device can safely disconnect from the circuit in the event of a fault, maintaining the integrity of the power system.

Advantages

This surge arrester offers exceptional reliability in safeguarding electrical systems against sudden voltage spikes caused by atmospheric discharges or switching operations. Its compact design allows for efficient installation in various distribution boards, while the built-in disconnector provides an essential safety feature that prevents thermal runaway and fire hazards. By stabilizing voltage levels, the device contributes to the extended lifespan of connected equipment and reduces the risk of costly downtime in both residential and industrial environments.

Suitable for

  • Residential electrical distribution panels
  • Industrial power supply systems
  • Protection of sensitive electronic control units
  • General low-voltage electrical installations

When it may not be suitable

This device is specifically rated for 440V systems and should not be used in installations with significantly higher or lower voltage requirements, as this may compromise its protective capabilities. It is also not intended for use in high-voltage transmission lines or environments where extreme environmental conditions exceed the manufacturer's specified operating parameters.

Key specifications

  • Rated voltage: 440V
  • Discharge current: 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 or a sub-distribution panel. Ensure that the device is connected in parallel with the load it is intended to protect and that the grounding connection is secure and has low impedance to allow for effective discharge of transient energy.

What to consider before purchase

  • Verify that the system voltage matches the 440V rating
  • Ensure there is sufficient space in the distribution board for installation
  • Confirm that the grounding system is properly installed and functional

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 full protection to your electrical system.
