Why Choose the Lovato SG24PA300 Surge Protection Device?

The Lovato SG24PA300 is a high-performance Type 2 surge protection device (SPD) designed to protect low-voltage three-phase electrical installations against transient overvoltages caused by indirect lightning strikes and switching operations. As part of the proven Lovato SG2 surge protection range, it provides dependable protection for commercial, industrial and photovoltaic AC distribution systems.

Designed for 230/400 V AC power systems, the SG24PA300 features a 4-pole configuration with plug-in replaceable protection cartridges for simplified maintenance and reduced downtime. Its compact DIN rail mounted design allows fast installation within switchboards, distribution panels and industrial control cabinets while ensuring long-term reliability.

With a 20 kA nominal discharge current (In) per pole and a 50 kA maximum discharge current (Imax), the SG24PA300 complies with IEC/EN 61643-11, helping protect valuable electrical equipment against damaging voltage transients whilst maintaining system availability.
