Modulostar® is a fuse disconnector designed for applications with power cylindrical low voltage fuses, produced by Mersen, professionals in the field of electrical protection and control for electrical power systems.
Fuse disconnectors with fast access to the fuse and compact design
Modulostar® is modular. Models are available from 1 to 4 poles for cylindrical fuses with 690VAC/DC voltage rating as per IEC and for some part numbers up to 1000VAC/DC rating as per both IEC and UL. Modulostar® is snapped easily on DIN rail via a slight push. Access to the fuse is fast. Simple blown fuse indication for models concerned. The indicator is located on the front of the fuse carrier. Two LEDs fulfil this function for alternating and direct currents. Modulostar® is compact. The space-saving Modulostar® fuse holder is almost 10mm shorter than the previous line. The new design is made through modern and tightened lines, leading to a more compact shape. Compactness drives to increased energy efficiency, with this new design Modulostar® features lower power losses.
Fuse disconnectors with robust and rigid moulded-plastic case
Modulostar® is robust. The moulded-plastic case of the holder is robust and rigid enough for use in the most demanding environments like process industries and transportation. This new fuse holder features high-grade plastic materials. They are classified UL V0 to V2 and R22HL2, complying with the new EN45545 regulation for rail transportation. The fuse holder can be opened and closed quickly with clear sound confirmation. The new Modulostar® withstands high tightening torques for cabling; 2Nm is the recommended torque, but the product has been tested up to 50% higher (3Nm). Unlocking the holder from DIN rail after mounting is very easy, simply use a screwdriver to actuate the rail lock built into the moulded-plastic envelope.
