Live Electrical SPV240 2-Pole 20kA/40kA Type 2 DC Surge Protection Device

Product Overview

The Live Electrical SPV240 2-Pole Type 2 DC Surge Protection Device (SPD) provides reliable protection against transient overvoltages in DC power and solar photovoltaic (PV) systems. Designed for high-performance protection up to 1000VDC, the SPV240 safeguards sensitive components and equipment from surge damage caused by lightning strikes or electrical switching events.

Built with high-energy varistors and integrated thermal disconnect technology, this SPD ensures fast response and safe operation during fault conditions. Its plug-in protection module allows for quick installation and easy maintenance, while optional remote signalling supports monitoring in larger installations. Compliant with IEC/EN 61643-31 standards, the SPV240 is a robust and dependable choice for DC surge protection in renewable and industrial systems.
