Why Choose the Lovato SA1B1PA320R Surge Protection Device?
The Lovato SA1B1PA320R is a high-capacity Type 1, Type 2 and Type 3 monoblock surge protection device (SPD) designed to protect low-voltage AC electrical installations against direct lightning effects, induced surges and switching overvoltages. Its single-pole configuration is intended for protecting an individual phase conductor in suitable electrical distribution systems.
With an IEC impulse current rating of 25 kA per pole using a 10/350 µs waveform, the SA1B1PA320R is engineered for demanding installations exposed to severe surge conditions. Its monoblock construction combines high discharge capability with a compact two-module DIN rail format, helping panel builders create reliable and space-efficient protection systems.
The device has a maximum continuous operating voltage of 320 V AC, a nominal discharge current of 25 kA and a maximum discharge current of 100 kA. An integrated remote signalling contact allows its operating status to be monitored through an alarm, building management system or industrial control system.

High-Capacity Protection Against Lightning and Switching Surges
Surge protection devices divert damaging transient currents away from connected equipment and safely discharge them towards earth. This helps protect electrical insulation, automation equipment and sensitive electronics from premature failure while reducing the risk of costly system downtime.
The Lovato SA1B1PA320R combines multiple surge protection classes within a durable monoblock assembly. Its 25 kA impulse current rating enables it to manage partial lightning currents, while its 100 kA maximum discharge capacity provides robust protection against severe transient overvoltages.
Typical Applications
- Main electrical distribution boards.
- Commercial and industrial switchboards.
- Buildings with external lightning protection systems.
- Industrial machinery and automation panels.
- Building management and monitoring systems.
- Protection of PLCs and variable speed drives.
- Critical electronic and control equipment.
