Special features
Primary fuse block
Epoxy encapsulated construction with laminations of high-quality silicon steel minimizes core losses and optimizes performance, delivering lower operating temperatures and improved efficiency in demanding 50/60 Hz environments. This translates to longer transformer life and reduced maintenance, especially in continuous operation within control panels and automation stations. Copper windings provide low resistance and stable thermal characteristics, resulting in reduced voltage drop under load and tighter control voltage for reliable relay operation—ideal for 120/240 V to 24 V control circuits. Molded-in terminals offer durability and straightforward wiring, speeding up installation and reducing field fault potential in crowded panels. The factory-mounted two-pole primary fuse block delivers built-in protection, simplifying code compliance and enhancing safety by interrupting faults at the source. Certifications and RoHS compliance further reduce procurement risk while ensuring regulatory alignment for North American manufacturing. A compact footprint (3.8 in depth, 4.5 in width, 5.29 in height) and a 9.2 lb weight allow flexible mounting in tight spaces without compromising service life.
