Finder 7P.24.8.275.1020 Type 2 surge protection device for three-phase TT and TN-S systems with 3+NPE configuration, replaceable varistor and spark gap modules, 20 kA nominal discharge current and DIN rail mounting.
£249.56
The Finder 7P.24.8.275.1020 is a high-performance Type 2 surge protection device (SPD) designed to protect three-phase TT and TN-S low-voltage electrical systems from transient overvoltages caused by induced lightning surges and switching events. As part of the dependable Finder 7P Series, it provides reliable protection for industrial, commercial and infrastructure electrical installations.
The device combines three replaceable varistor modules with an encapsulated spark gap module to provide coordinated protection between L1, L2, L3, neutral and protective earth. Visual indication together with an integrated remote signalling contact allows quick monitoring of the protection status, reducing maintenance time and improving system availability.
With a 230 V AC nominal voltage, 275 V AC maximum continuous operating voltage, 20 kA nominal discharge current and 40 kA maximum discharge current, the Finder 7P.24.8.275.1020 is ideal for protecting distribution boards, industrial control panels, automation systems and sensitive electronic equipment.
Type 2 surge protection devices reduce the risk of damage caused by transient overvoltages by diverting surge energy away from sensitive electrical equipment. This helps protect PLCs, drives, power supplies, switchgear, instrumentation and automation equipment while improving the reliability of electrical installations.
The Finder 7P.24.8.275.1020 is designed for installation in three-phase distribution boards and control panels where coordinated Type 2 protection is required. Its replaceable protection modules, DIN rail mounting and integrated signalling functions make it an ideal solution for demanding industrial and commercial applications.
