Why Choose the Lovato SG2C3NA275R Surge Protection Device?
The Lovato SG2C3NA275R is a compact Type 2 surge protection device (SPD) designed to protect low-voltage AC electrical installations against transient overvoltages caused by indirect lightning effects and switching events. Part of the Lovato SG2C surge protection range, this 3P+N device uses replaceable plug-in cartridges and is intended for three-phase AC power distribution systems.
The SG2C3NA275R has a rated discharge current In of 20 kA and a maximum discharge current Imax of 40 kA using the 8/20 µs waveform. Its maximum continuous operating voltage Uc is 275 V AC, while the voltage protection level Up is below 1.5 kV for both L-N and N-PE protection paths.
Designed for 230 V AC rated systems, the SG2C3NA275R incorporates thermal protection, frontal operating/end-of-life indication and an auxiliary remote status contact. Its compact two-module DIN rail construction makes it well suited to secondary distribution boards, industrial control panels and other installations requiring dependable three-phase surge protection.
