Product Introduction
The TZG40-B/C/D series surge protective devices (SPDs) are advanced shielded surge protectors featuring a newly designed tripping mechanism that enables efficient and rapid surge absorption. Available in 1P, 2P, 3P, and 4P configurations, these Type 2 SPDs are suitable for AC power circuits operating at 110V or 220V, with rated voltages of 275V, 385V, or 420V. They offer nominal discharge current (In) options of 10kA, 20kA, or 30kA, and corresponding maximum discharge current (Imax) ratings of 20kA, 40kA, or 60kA. Fully compliant with IEC/EN 61643-11, the TZG40 series provides reliable protection for household appliances and other sensitive equipment against lightning surges and transient overvoltages.
