Why Choose the Lovato SA0B3PA320R Type 1+2 Surge Protection Device?

The Lovato SA0B3PA320R is a high-performance Type 1+2 surge protection device (SPD) designed to protect three-phase AC electrical installations against transient overvoltages associated with lightning events and induced electrical surges. As part of the Lovato Electric SA0B monoblock series, it combines Type 1 and Type 2 surge protection within a compact device for low-voltage power distribution systems.

Designed with a 3P pole configuration, the SA0B3PA320R provides an IEC impulse current Iimp of 12.5 kA per pole, a rated discharge current In of 20 kA and a maximum discharge current Imax of 50 kA. Its monoblock construction makes it suitable for installations requiring robust lightning and surge protection without the need for separate Type 1 and Type 2 protective devices.

The SA0B3PA320R is designed for AC power lines and has a maximum continuous operating voltage Uc of 320 V AC. It also incorporates thermal protection, frontal operating/end-of-life indication and a remote changeover contact, allowing the condition of the SPD to be monitored locally or remotely within electrical control and building management systems.

Key Advantages

  • Combined Type 1 and Type 2 surge protection in a single monoblock device.
  • 3P configuration for three-phase AC electrical systems.
  • 12.5 kA Iimp impulse current per pole for high-energy lightning surge protection.
  • 50 kA maximum discharge current Imax for effective transient overvoltage protection.
  • <1.5 kV voltage protection level Up to limit transient voltage reaching connected equipment.
  • Integrated remote status contact and frontal operating/end-of-life indication.

Key Features

  • Lovato Electric SA0B monoblock series.
  • Type 1+2 surge protection device.
  • 3P pole configuration.
  • 320 V AC maximum continuous operating voltage Uc.
  • 12.5 kA Iimp (10/350 µs) impulse current per pole.
  • 20 kA rated discharge current In (8/20 µs).
  • 50 kA maximum discharge current Imax (8/20 µs).
  • <1.5 kV voltage protection level Up.
  • Integrated thermal protection.
  • Frontal status indication with remote changeover contact.
  • Compact three-module DIN rail mounting.

Reliable Protection Against Lightning and Transient Overvoltages

Surge protection devices such as the Lovato SA0B3PA320R divert damaging transient surge currents away from electrical equipment and help limit the voltage reaching connected installations. Its combined Type 1+2 design provides protection against high-energy lightning currents with a 10/350 µs waveform as well as induced transient overvoltages characterised by an 8/20 µs waveform.

The SA0B series is designed for installations requiring coordinated surge protection within electrical distribution systems. With high impulse and discharge current capability, thermal protection, local status indication and remote signalling, the SA0B3PA320R provides dependable protection for three-phase electrical installations and connected equipment.

Typical Applications

  • Main three-phase electrical distribution boards.
  • Commercial and industrial electrical installations.
  • Three-phase power distribution systems.
  • Installations exposed to lightning and induced overvoltages.
  • Electrical control and automation panels.
  • Non-urban installations requiring combined Type 1 and Type 2 surge protection.
