Description

The ABB MVR0.44-10KA is a medium-voltage surge arrester designed to protect electrical equipment from transient voltage spikes in medium-voltage power distribution systems. Here’s a breakdown of its function and key characteristics:

Function:

  • Surge arresters like the ABB MVR0.44-10KA safeguard electrical equipment from sudden voltage surges caused by lightning strikes, switching operations, or other transient events.
  • These surges can damage insulation, degrade component performance, and lead to equipment failure.
  • The MVR0.44-10KA diverts these high-voltage surges away from sensitive equipment by providing a low-impedance path to ground.

Key Characteristics:

  • Voltage Rating: 0.44 kV (kilovolts) – This indicates the maximum continuous operating voltage the surge arrester can handle in AC systems.
  • Current Rating: 10 kA (kiloAmperes) – This specifies the maximum surge current the arrester can safely divert to ground.
  • AC/DC Compatibility: The MVR datasheet (refer to “Finding Specific Information” section below) will clarify if this specific variant (MVR0.44-10KA) is suitable for both AC and DC systems or only AC systems.
