Why Choose the Mersen H220071 Fuse Disconnector?
The Mersen H220071, also identified as the PS I 27.60 PRE or PSI27X60PRE, is a robust industrial fuse disconnector designed for use with compatible cylindrical ferrule fuse-links. It combines secure fuse mounting with a practical disconnection function, helping operators isolate protected circuits during inspection, maintenance and fuse replacement.
Designed for demanding electrical installations, the H220071 provides strong thermal and mechanical performance. Its pre-isolating configuration helps improve operational safety by allowing the circuit to be disconnected before direct access to the installed fuse-link, making it suitable for industrial control panels, power conversion equipment and machinery.
The unit accommodates compatible 27 × 60 mm cylindrical fuse-links and is rated for applications up to 1000 V and 300 A, subject to the selected fuse-link and installation conditions. Its durable construction supports dependable service in industrial environments where reliable circuit protection and accessible isolation are essential.
