Motor Circuit Protection Fuses

Motor Circuit Protection Fuses
Motor protection fuses are specially designed for use in a motor circuit (according to IEC 60644) and are available in DIN standard and British Standard design, providing great choice and flexibility to designers of switchboard panels. These fuses provide high reliability against cyclic and peak current loads and incorporate age resistant technology needed to cope with high motor start-up currents. They also feature low power losses thus minimising temperature increases in narrow contactor enclosures and low minimum interrupting currents for operation of over-currents in the range 3 - 3.5 times rated current.

Fuseco is proud to offer the SIBA brand of medium voltage fuses. SIBA is a long established German fuse manufacturer that is widely considered to produce the highest quality MV fuses in the world. SIBA MV fuses have parallel connected pure silver fuse elements, ensuring narrow tolerances of the time/current characteristics. SIBA DIN fuses (up to and including 160A) also contain the SIBA temperature limiter mechanism that protects the against inadmissible temperature rises, a unique feature that has become a 'must have' choice for many protection engineers.
