Why Choose the Lovato SA0B1NA320R Type 1+2 Surge Protection Device?
The Lovato SA0B1NA320R is a Type 1+2 monoblock surge protection device (SPD) designed to protect AC power installations against transient overvoltages and high-energy surge currents. Its 1P+N configuration is intended for compatible 230 V AC single-phase power systems.
Designed for demanding primary distribution applications, the SA0B1NA320R provides an IEC impulse current Iimp (10/350 µs) of 12.5 kA per pole. It also provides a rated discharge current In (8/20 µs) of 20/50 kA for L-N/N-PE paths and maximum discharge current Imax (8/20 µs) of 50/100 kA.
The device has a maximum continuous operating voltage Uc of 320 V, a voltage protection level below 1.5 kV and integrated frontal status indication. A remote changeover contact enables remote monitoring of SPD status, while the compact 2-module DIN rail format supports straightforward integration into professional electrical distribution panels.

Reliable Type 1+2 Surge Protection
The Lovato SA0B1NA320R combines Type 1 and Type 2 SPD functions in a single device, allowing it to handle high-energy 10/350 µs impulse currents as well as 8/20 µs surge currents. Its 12.5 kA Iimp capability and low voltage protection level make it a robust choice for coordinated surge protection in compatible AC distribution systems.
Integrated thermal protection and frontal end-of-life indication simplify inspection and maintenance, while the built-in changeover remote contact enables status signalling to external monitoring or control equipment. This combination makes the SA0B1NA320R particularly useful in professional installations where both effective surge protection and remote condition monitoring are required.
Typical Applications
- Single-phase AC electrical distribution systems.
- Main and primary electrical distribution boards.
- Industrial control and automation panels.
- Commercial building electrical installations.
- Machine and equipment power distribution systems.
- Installations requiring coordinated Type 1+2 surge protection.
- Systems requiring remote monitoring of SPD operating status.
