Special features
Bolt-on mounting50° C Calibration
Three-pole, bolt-on thermal-magnetic design delivers robust overcurrent protection; this reduces nuisance trips and guards motors and feeders in demanding environments. It supports quick field retrofits in panel boards and motor control centers, speeding installation and reducing downtime. The 90 A, 240 V rating paired with a 10 kAIC interrupt capacity ensures reliable fault current interruption for medium-to large-scale industrial systems, protecting downstream equipment and reducing repair costs. A 50°C calibration feature maintains consistent trip characteristics across elevated ambient temperatures, improving predictability in hot plant areas and minimizing unexpected shutdowns. Certifications including CSA Certified and UL Listed, plus HACR rating, provide regulatory confidence for HVAC and motor loads and help streamline audit processes. Bolt-on mounting and a compact footprint support scalable protection while simplifying future expansions and maintenance.
