£239.17
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.
Type 1 and Type 2 surge protection devices are designed to limit dangerous transient overvoltages before they can damage electrical and electronic equipment. The Lovato SA0B2PA320R is capable of handling both high-energy 10/350 µs lightning-current impulses and 8/20 µs surge currents, making it suitable for installations where protection against direct and induced surge effects is required.
Its DIN rail monoblock construction allows straightforward installation within electrical distribution equipment, while frontal status indication and the remote relay contact provide convenient local and remote monitoring. Integrated thermal protection further supports reliable operation in industrial and commercial power distribution systems.
