Why Choose the MERSEN FUSE PS I 27.60 PRE PSI27X60PRE?
£160.87
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.
Fuse disconnectors provide a secure interface between a fuse-link and the protected electrical circuit while also enabling intentional circuit isolation. This allows maintenance personnel to disconnect equipment and access the fuse more safely than with a basic fixed fuse holder.
The Mersen H220071 is intended for applications that require dependable mechanical operation, strong electrical performance and convenient fuse replacement. The protective capability of the completed installation depends on the compatible fuse-link selected, the circuit characteristics and compliance with the applicable electrical installation requirements.
