SA1B2PA320R - SURGE PROTECTION DEVICE TYPE 1-2 2P

Why Choose the SA1B2PA320R?

Lovato’s SA1B2PA320R surge protection device is a Type 1 and 2 SPD for 230/400VAC systems. This 2‑pole monoblock delivers Iimp 25kA per pole to withstand severe transients at the service entrance. DIN rail mounting streamlines panel installation, and the integrated remote contact allows connection to monitoring or control circuits. Built for AC applications, it provides dependable protection for main and sub‑distribution boards in commercial, industrial, and infrastructure environments.

Engineered to IEC/EN 61643-11, the SA1B family ensures reliable performance under demanding conditions. The unit offers nominal discharge current In 25kA and short-circuit rating Isccr 25kA, supporting robust fault withstand. It operates from -40 to +80 °C up to 2000 m altitude, in a compact 395 g housing. With the SA1B type designation, this DIN-rail SPD integrates cleanly into panels, delivering consistent surge mitigation across AC distribution networks.
