Two-pole design with a 40 A rating and a 10 kAIC interrupt capacity delivers rapid fault clearing, reducing arc energy, equipment damage, and downtime. In motor feeders and general control circuits, this capability translates to higher uptime and safer shutdowns in congested panel enclosures. Bolt-on mounting and the Quicklag family design simplify field installation, cutting install time and trimming hardware counts. For panel builders and maintenance teams, this means repeatable mounting in compact spaces and easier future replacements. Voltage rating of 120/240 V and HACR compatibility expand suitability for HVAC and mixed-load applications, enabling safe operation across common industrial equipment. Compact dimensions (4 in L, 4.9 in H, 2.2 in W) and a light 0.65 lb weight streamline enclosure planning and inventory management, while a 1-year warranty supports predictable maintenance budgeting. Certifications UL Listed and CSA Certified enhance regulatory acceptance and reliability in regulated markets.
