Why Choose the Lovato SA02PA320R Surge Protection Device?
The Lovato SA02PA320R is a combined Type 1 and Type 2 surge protection device (SPD) designed to protect low-voltage AC electrical installations against lightning impulse currents and transient overvoltages. Its two-pole configuration makes it suitable for single-phase systems where coordinated protection is required across the line and neutral conductors.
Featuring replaceable plug-in protection cartridges, the SA02PA320R allows straightforward maintenance without replacing the complete surge protection assembly. An integrated remote signalling contact enables the operating condition of the device to be monitored through an alarm, control system or building management system.
With an impulse discharge current of 12.5 kA per pole using a 10/350 µs waveform, a nominal discharge current of 20 kA per pole and a maximum discharge current of 40 kA per pole, the SA02PA320R provides dependable protection for distribution boards, switchboards and industrial control panels.

Reliable Protection Against Lightning and Switching Surges
Surge protection devices divert damaging transient currents away from connected electrical equipment and safely discharge them towards earth. This helps reduce the risk of insulation damage, electronic component failure, unplanned downtime and premature equipment replacement.
By combining Type 1 and Type 2 protection, the Lovato SA02PA320R can manage partial lightning currents while also limiting switching surges and induced transient overvoltages. Its remote signalling contact supports continuous monitoring, while the replaceable cartridges help reduce maintenance time and lifecycle costs.
Typical Applications
- Single-phase main distribution boards.
- Industrial control panels and switchboards.
- Commercial electrical installations.
- Building management and automation systems.
- Machinery control cabinets.
- Installations with external lightning protection systems.
- Protection of PLCs, drives and sensitive electronic equipment.
