Feature The 60A amperage rating with 240V, two-pole configuration provides solid overload protection while enabling safe isolation of motor circuits. Business Impact This reduces the risk of electrical faults propagating through the line, minimizes unplanned downtime, and supports predictable startup sequences in conveyors, pumps, and presses. Application Use this in motor-driven equipment where reliable 60A protection and a straightforward neutral path are required, such as packaging lines and material handling systems. Feature The NEMA 3R enclosure with painting on galvanized steel delivers high durability in harsh environments. Business Impact It resists weathering, corrosion, and incidental impacts, extending service life and reducing enclosure maintenance costs. Application Suitable for outdoor service entrances, control panels in damp facilities, and washdown environments where protection against moisture is essential. Feature Class H fuse provision and fusible with neutral configuration support flexible protection strategy. Business Impact Enables easy coordination with upstream protection, improving selectivity and fault clearance while preserving downstream equipment. Application Ideal for integrated control panels and switchgear where precise fuse management and neutral conductors are required. Feature Compact footprint and defined dimensions plus a 19 lb weight simplify installation and cabinet integration. Business Impact Improves install time, reduces space requirements, and lowers handling costs during upgrades or replacements. Application Fits within limited control-room or equipment enclosures, aiding OEMs and facilities teams with retrofit projects. Feature UL Listed and CSA Certified with a one-year warranty provides procurement confidence and regulatory alignment. Business Impact Streamlines compliance documentation, supplier qualification, and maintenance planning while delivering post-sale support. Application Useful across industrial facilities that demand recognized safety certifications for electrical protection devices.
