Why Choose the Mersen H097297 PS III Fuse Disconnector?
The Mersen H097297, also identified as PS III 20.127 PRE BS +MC PS, is a heavy-duty three-pole non-load fuse disconnector designed for the secure installation and isolation of cylindrical semiconductor fuse-links. Part of the Mersen PS 20 × 127 mm modular fusegear range, it combines corrosion-resistant construction with integrated microswitch functionality for demanding industrial, renewable energy and transportation applications.
Designed for use with compatible 20 × 127 mm ferrule semiconductor fuse-links, the H097297 features a salt spray-resistant (BS) construction, making it ideal for marine, offshore, railway and outdoor electrical installations. The integrated +MC PS microswitch provides remote indication when a compatible striker-equipped fuse operates, allowing maintenance teams to identify faults quickly and minimise downtime.
Suitable for systems operating up to 1500 V AC/DC and compatible with fuse ratings up to 125 A, the H097297 delivers secure fuse mounting, dependable electrical performance and safe circuit isolation for converters, inverters, battery storage systems and other critical power electronic equipment.
