Overview

The Mersen Surge-Trap® Pluggable SPD (STP480SPGM) is a no-fuse, fail-safe surge protective device designed for 240/480V split phase systems. Utilizing Mersen’s patented TPMOV® technology, this UL 1449 5th Edition-listed SPD eliminates the need for external fuses, fuse holders, or additional wiring, significantly reducing installation time and costs. The pluggable design allows for quick and easy module replacement without rewiring or touching the base, while mechanical coding prevents incorrect installation. Key features include a visual status indicator (green = functional, red = replace), remote monitoring via Form C dry contacts, and a high short-circuit current rating (SCCR) of 200kA. The device is DIN-rail mountable on 35mm rails, supports wire ranges from 4-14 AWG, and operates in temperatures from -40°C to +85°C. With a surge capacity of 75kA and nominal discharge current of 10-20kA (8x20 µs), it is ideal for industrial control panels, water treatment, smart grid/LV metering, and traffic/ITS applications. The IP20 finger-safe design and UL94 V0 flammability rating ensure safety in harsh environments. Backed by a 5-year warranty, the STP480SPGM delivers reliable overvoltage protection with minimal maintenance.
