Mersen UltraSafe™ Fuse Modules have a unique, compact design suited for use with 45mm wide IEC contactors. These modules also offer other features not found on other Class CC and midget UltraSafe fuse holders such as an auxiliary contact option. When the auxiliary is wired to an adjacent contactor the load is dropped out by the contactor immediately once someone tries to open the fuse extractor handle. Additionally, the fuse module features padlock capabilities, compact busbars for line side terminations, and tool free removal from DIN-rail. Yet the fuse modules still incorporate well known UltraSafe features such as IP20 protection, easy operating fuse extraction handles and an open fuse visual indication option.

Mersen DC high performance power fuses were developed to provide superior protection for railway power circuits.
These fuses are typically operated at more elevated temperatures than other fuse types.
They have lower I2t to minimize damage to components in case of short circuits, and have lower watts loss and longer life.

Fork Design
Wiring bars in fork design are ideal for the wiring of modular panel-mounting devices as per DIN 43880 with flat-type, dual-function or single-screw terminals.
Additional incoming terminals are required when wiring devices with flat-type or single-screw terminals.
In contrast, devices with dual-function terminals allow bar connection to the top section of the terminal with simultaneous incoming supply in the bottom section.
The use of end caps on multi-pole wiring bars guarantees optimum shock-hazard protection and prevents arcing at bar ends.L@£Pin Design
Wiring bars in pin design are ideal for the wiring of modular panel-mounting devices to DIN 43880 with box terminal, frame terminal or two-scre clamp.
The incoming supply to the wiring-bar system is provided over additional incoming terminals.
