Special features
Bolt-on mounting
Feature: Thermal-magnetic protection provides both instantaneous magnetic trip for short circuits and slow-responding thermal protection for overloads, delivering precise selectivity. Business impact: This combination minimizes nuisance trips and protects motor windings, reducing unplanned downtime and extending equipment life. Application: Ideal for industrial motor circuits, feeders, and panel-board assemblies in challenging factory environments where reliable protection is essential. Paragraph continues with practical installation and compatibility advantages: Feature: Quicklag industrial design with bolt-on mounting simplifies installation and field upgrades. Business impact: Faster commissioning and easier retrofits lower labor costs and downtime during maintenance windows. Application: Compatible with standard control panels and enclosures, enabling straightforward integration into existing electrical architectures. Paragraph continues with specifications and remote-control options: Feature: 125 A amperage rating with a 10 kAIC interrupt capacity at 120/240 V ensures safe interruption of high fault currents. Business impact: Improves system safety and reduces the risk of cascading faults, while non-interchangeable trip prevents accidental replacement with an incorrect device. Application: Well-suited for medium-size motor feeders and general-purpose circuits in manufacturing lines. The shunt-trip option (120–240 V) supports remote disconnect control. Paragraph continues with certifications: Feature: Certifications and ratings include UL Listed, CSA Certified, and HACR-rated compatibility for HVAC and general electrical installations. Business impact: These credentials simplify procurement, streamline compliance paperwork, and support audits in regulated environments. Application: Suitable for new builds and retrofit projects where code compliance and reliability are non-negotiable. Paragraph ends with compactness and reliability: Feature: Compact footprint and durable construction: 3.8 in depth, 4.8 in height, 2.3 in width, and about 0.65 lb with a robust bolt-on mount. Business impact: Space efficiency in crowded panels, reduced shipping weight, and easier inventory management. Application: Fits standard electrical panels and can be replaced with minimal cabinet modification, backed by a 1-year warranty.
