Why Choose the Lovato SA0B2PA320R Surge Protection Device?
The Lovato SA0B2PA320R is a high-performance Type 1 and Type 2 monoblock surge protection device (SPD) designed to protect AC electrical installations against transient overvoltages caused by lightning currents and switching events. As part of the Lovato SA0B series, this 2-pole device combines Type 1 and Type 2 surge protection in a compact DIN rail format for industrial, commercial and distribution applications.
The SA0B2PA320R provides an impulse current Iimp of 12.5 kA per pole with a 10/350 µs waveform and a maximum discharge current Imax of 50 kA with an 8/20 µs waveform. Its monoblock construction, frontal status indication and integrated thermal protection provide a robust solution for protecting sensitive electrical equipment and downstream circuits.
Designed for 230 V AC systems, the SA0B2PA320R has a maximum continuous operating voltage Uc of 320 V AC and a voltage protection level Up below 1.5 kV. An integrated changeover relay contact enables remote monitoring of SPD status, making the unit particularly suitable for monitored electrical distribution and automation installations.
