Why Choose the Lovato SA0B2PA320R-ENC Surge Protection Device?
The Lovato SA0B2PA320R-ENC is an enclosed two-pole Type 1+2 surge protection device (SPD) designed to protect low-voltage AC electrical installations against transient overvoltages caused by lightning and switching events. Built around the proven Lovato SA0B Type 1+2 monoblock SPD, it provides coordinated lightning-current and surge protection for power distribution applications.
The two-pole SPD has a maximum continuous operating voltage of 320 V AC and an impulse current Iimp of 12.5 kA per pole with a 10/350 µs waveform. It also provides a maximum discharge current Imax of 50 kA with an 8/20 µs waveform and a voltage protection level Up of less than 1.5 kV.
The SA0B2PA320R-ENC is based on a monoblock SPD with integrated thermal protection, frontal operating/end-of-life indication and a remote status contact. Its enclosed format provides a practical complete surge-protection assembly for electrical distribution systems where a housed Type 1+2 protective solution is required.

Reliable & Durable Surge Protection
Type 1+2 surge protection devices are designed to handle both high-energy lightning-current impulses and lower-energy transient overvoltages induced within an electrical installation. The Lovato SA0B2PA320R-ENC combines these functions in a two-pole enclosed solution suitable for installation near the incoming power distribution point.
Its 12.5 kA per-pole Iimp rating, 50 kA maximum discharge capability and voltage protection level below 1.5 kV provide robust protection for downstream electrical and electronic equipment. Integrated status indication and a remote contact also simplify inspection and remote monitoring of the protective device.
Typical Applications
- Main low-voltage distribution boards.
- Industrial and commercial electrical installations.
- Single-phase power distribution systems.
- Machinery and automation power supplies.
- Building electrical distribution systems.
- Installations exposed to lightning-related and induced transient overvoltages.
