Surge protection

摘要

Mersen has introduced the Surge-Trap pluggable SPD, which provides advanced overvoltage protection by using a TPMOV design that does not require fuses, a fuse holder, or additional wiring in meeting UL 1449 third-edition standards. The SPD base is designed to be mounted on a 35 mm DIN-rail while plugs are easily replaceable upon failure without touching the base or the hassle of rewiring. It also features a visual indicator, easy installation, fail-safe design, mechanical coding, and remote monitoring.
