Overview

The Mersen E091935 is a robust fuse base designed for high voltage fuse-links, rated at 2.5kVAC and 200A. This specific model accommodates fuse sizes of 36x127mm, ensuring compatibility with a range of Mersen ferrule-type fuses. Engineered for reliability, these fuse holders offer excellent vibration withstand capabilities, tested with sine vibrations across three axes (2-16 Hz at 5mm peak displacement and 16-250 Hz at 5g peak acceleration). This makes them suitable for applications where mechanical stability is paramount. The fuse bases are constructed with materials offering good thermal and mechanical withstand ratings. Options include models with or without open fuse indicating microswitches, and different material choices like phenolic resin for basic applications or fiberglass polyester for corrosive atmospheres or traction applications. The Mersen E091935 is manufactured in the US and is UL Recognized component (File E113357), signifying adherence to safety standards. Its dielectric withstand capabilities include 6kV (1) / 10 kV (2) for 1-minute RMS voltage at 50/60 Hz and 12 kV (1) / 20 kV (2) for impulse voltage (1.2/50 s).
