Mersen J097229 PS IV 20.127 PRE fuse holder and disconnector for compatible 20 × 127 mm cylindrical semiconductor fuse-links in industrial electrical protection systems.
£310.64
The Mersen J097229 is a robust fuse holder and disconnector designed for use with 20 × 127 mm semiconductor fuse-links in industrial power conversion and electrical protection systems. Also identified as the PS204PRE or PS IV 20.127 PRE, it provides a secure means of installing, isolating and replacing compatible cylindrical fuse-links.
Manufactured for demanding industrial environments, the J097229 features a durable fibreglass-reinforced polyester construction. This provides mechanical strength and dependable electrical insulation while supporting safe operation within switchgear, converter cabinets and industrial control assemblies.
The Mersen J097229 combines fuse mounting and circuit isolation in a single assembly, helping simplify maintenance and improve operational safety. Its elongated enclosure is designed to accommodate the associated 20 × 127 mm fuse-link while providing convenient access for inspection and replacement.
Fuse disconnectors provide a practical method of isolating protected equipment while retaining the rapid fault-clearing performance of the installed fuse-link. By combining fuse mounting with a manually operated disconnection function, maintenance personnel can isolate a circuit before inspecting or replacing the fuse.
The Mersen J097229 is intended for industrial systems where compatible 20 × 127 mm fuse-links are used to protect semiconductors and power electronic equipment. Correct fuse-link selection must be based on the equipment voltage, operating current and required protection characteristics.
