Lovato SA01NA320R combined Type 1 and Type 2 surge protection device with 1P+N configuration, 320V AC maximum continuous operating voltage, plug-in cartridges and remote signalling contact.
£206.56
The Lovato SA01NA320R is a combined Type 1 and Type 2 surge protection device (SPD) designed to protect low-voltage electrical installations against lightning impulse currents and transient overvoltages. Its 1P+N configuration makes it suitable for single-phase systems where both the line and neutral require coordinated surge protection.
Featuring replaceable plug-in protection cartridges, the SA01NA320R supports straightforward maintenance without replacing the complete device. It provides an impulse discharge current of 12.5 kA per pole with a 10/350 µs waveform, together with a nominal discharge current of 25 kA using an 8/20 µs waveform.
The device has a maximum continuous operating voltage of 320 V AC and includes a remote signalling contact for integration with alarms, building-management systems or remote monitoring equipment. Its DIN rail format makes it suitable for installation within distribution boards, switchboards and industrial control panels.
Surge protection devices divert damaging transient currents away from sensitive electrical equipment and safely discharge them towards earth. This helps reduce the risk of insulation failure, electronic-component damage, unplanned downtime and premature equipment replacement.
By combining Type 1 and Type 2 protection, the Lovato SA01NA320R can handle partial lightning currents entering an installation while also limiting lower-energy switching and induced surges. Its remote contact allows the device status to be monitored without requiring direct visual inspection of the distribution board.

It protects single-phase electrical installations and connected equipment against lightning impulse currents, switching surges and transient overvoltages.
Type 1 protection is designed to handle partial lightning currents, while Type 2 protection limits transient overvoltages caused by indirect lightning effects and electrical switching operations.
The device has an impulse discharge current rating of 12.5 kA per pole using a 10/350 µs waveform.
Yes. The SA01NA320R uses replaceable plug-in cartridges, allowing a spent cartridge to be changed without replacing the complete surge-protection assembly.
The remote contact provides an external indication of the surge protector's operating status and can be connected to an alarm, monitoring relay or building-management system.
Lovato surge protection devices are used by panel builders, electrical contractors and automation engineers to protect critical installations from transient overvoltages and support dependable system operation.
