Why Choose the Lovato SG13PA750RUL Surge Protection Device?
The Lovato SG13PA750RUL is a high-performance Type 1 and Type 2 surge protection device (SPD) designed to protect AC power installations against direct and indirect lightning effects, induced surges and transient overvoltages. Part of the Lovato SG1 surge protection range, this UL-certified 3-pole device combines Type 1 and Type 2 protection with replaceable plug-in cartridges for straightforward maintenance.
Designed for demanding industrial and commercial power distribution systems, the SG13PA750RUL provides a rated discharge current In of 20 kA per pole and an impulse current Iimp of 5 kA per pole. Its maximum continuous operating voltage Uc of 750 V AC makes it suitable for higher-voltage AC installations where robust surge protection is required.
The device incorporates frontal operating and end-of-life indication together with a changeover relay contact for remote status monitoring. DIN rail mounting, three-module construction and replaceable cartridges simplify integration and servicing within primary and intermediate electrical distribution boards.

Reliable Surge Protection for AC Distribution Systems
Combined Type 1 and Type 2 SPDs provide coordinated protection against high-energy lightning currents and lower-energy transient overvoltages within a single device. The Lovato SG13PA750RUL is designed to protect electrical infrastructure from direct and indirect lightning effects as well as switching and induced surges that could otherwise damage sensitive equipment.
Its replaceable cartridge construction allows individual surge protection elements to be serviced without replacing the complete base assembly. Frontal condition indication and the integrated remote signalling relay make the SG13PA750RUL particularly useful in industrial installations where protection status must be readily monitored.
Typical Applications
- Three-phase industrial AC power distribution systems.
- Primary electrical distribution boards.
- Intermediate distribution panels.
- Industrial machinery and automation installations.
- Commercial electrical distribution systems.
- Facilities requiring protection against lightning and switching overvoltages.
