Why Choose the Mersen 83230131 Surge Protection Device?
The Mersen 83230131 is a robust Type 2+3 Surge Protection Device (SPD) engineered to protect low voltage electrical installations against transient overvoltages. As part of the Mersen Surge-Trap® Pluggable STPT23 LF Series, it combines high surge protection performance with leakage current free technology, making it ideal for protecting sensitive electrical and automation equipment.
Designed for installation within electrical distribution boards and industrial control panels, this pluggable SPD helps divert damaging surges caused by lightning strikes and switching operations before they reach connected equipment. Its modular construction allows rapid cartridge replacement, reducing maintenance time while maintaining reliable protection.
With a maximum discharge current of 20 kA (8/20 μs), a 275 V AC continuous operating voltage (Uc) and a 4+0 TNS configuration, the Mersen 83230131 is ideally suited to protecting switchboards, motor control centres, PLCs, drives and industrial automation systems operating on 230/400 V AC networks.
