The Mersen USMSW3 is a genuine auxiliary microswitch contact kit designed for compatible Mersen UltraSafe™ US14 modular fuse holders. It enables remote signalling and status monitoring of fuse disconnector positions, making it ideal for industrial automation, control panels and switchgear applications.
The USMSW3 provides two auxiliary microswitches within a compact assembly, allowing control systems, PLCs or building management systems to monitor the operating status of compatible fuse holders. It is particularly suited to installations where remote indication improves maintenance efficiency and system diagnostics.
Designed specifically for the UltraSafe™ US14 range, this accessory integrates neatly with prepared fuse disconnectors and maintains the compact modular construction expected in modern industrial electrical installations.
Auxiliary contact kits allow the operating position of compatible fuse disconnectors to be monitored remotely by PLCs, SCADA systems or other control equipment. This improves operational awareness and can help reduce maintenance response times in industrial installations.
The Mersen USMSW3 is intended for prepared UltraSafe™ US14 fuse disconnectors and provides two auxiliary microswitches for reliable position signalling within automation and electrical distribution systems.
