Mersen is launching a brand-new Modulostar® fuse-disconnector for applications with power cylindrical low voltage fuses. Emmanuelle Delcambre, IEC Low Voltage Product Manager for Mersen introduces us the key features and benefits of the product:
“Modulostar® is simple. Simple because it 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. Simple because Modulostar® is snapped easily on DIN rail via a slight push. Simple because changing a fuse is easier thanks to the fuse carrier’s wider opening angle, the widest opening angle ever seen in the market. Access to the fuse is now fast. Simple blown fuse indication for models concerned. The indicator is located on the front of the fuse carrier. Two LEDs fulfill this function for alternating and direct currents. Simple because new fuse holders can be straight padlocked through a handy eyelet when the fuse carrier is in the open position.
Modulostar® is compact. The space-saving new 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.
Modulostar® is robust. The molded-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. 2N.m is the recommended torque, but the product has been tested up to 50% higher (3N.m). Unlocking the holder from DIN rail after mounting is very easy, simply use a screwdriver to actuate the rail lock built into the molded-plastic envelope.”
