Overview

The Mersen PS Series E097294 is a 3-pole, 1500V DC rated fuseholder designed for 20x127mm fuses, delivering robust protection in high-voltage industrial applications. Rated for 2500V dielectric withstand and 125A maximum operating current, this fuseholder is engineered for demanding environments where safety and reliability are critical. Each pole includes an integrated blown-fuse indicating microswitch, activated by a striker fuse, enabling immediate visual or electrical notification of fuse status. This feature minimizes downtime and accelerates maintenance in critical infrastructure such as renewable energy systems, industrial automation, and power distribution networks. The PS Series is available in 1, 2, 3, or 4-pole configurations, offering modular flexibility for diverse electrical architectures. Constructed from high-performance thermoplastic or thermoset materials, the E097294 meets UL 94 V0 flame retardancy standards and is UL Recognized under File E113357. Designed for compatibility with 20x127mm ferrule fuses, it supports copper wire sizes up to 50 mm² and rigid or flexible bars up to 15x8mm. With a short-circuit current rating (SCCR) of 42kA AC and 55kA DC, the E097294 ensures dependable protection against overcurrents and short circuits. Ideal for solar inverters, wind turbine control systems, motor control centers, and DC power distribution panels, this fuseholder combines advanced safety features with operational efficiency.
