Overview

The Mersen Surge-Trap® Pluggable SPD (SP150E) delivers advanced overvoltage protection for industrial environments with a 150V rating, designed for 35mm DIN-rail mounting. Utilizing Mersen’s patented TPMOV® technology, this no-fuse, fail-safe surge suppressor meets ANSI/UL 1449 5th Edition standards without requiring additional fuses, fuse holders, or wiring, reducing installation costs and time. The pluggable design allows for quick module replacement without rewiring or touching the base, minimizing downtime. Key features include a visual status indicator (green = functional, red = replace), remote monitoring via Form C dry contacts, and mechanical coding to prevent replacement errors. With a surge current rating (Imax) of 75kA, nominal discharge current (In) of 10–20kA, and a short-circuit current rating (SCCR) of 200kA, the SP150E is ideal for industrial control panels, water treatment, smart grid/LV metering, and traffic/ITS applications. The device operates at 50/60Hz, supports wire ranges from 4–14AWG, and features IP20 finger-safe design with UL94 V0 flammability rating. Backed by a 5-year warranty, the SP150E combines reliability, ease of maintenance, and compliance with RoHS standards for long-term performance in harsh environments.
