Special features
24,48V/dc shunt trip
Three-pole thermal-magnetic design with a 70 A rating and 10 kAIC interrupt capacity provides reliable overload protection for three‑phase circuits. This delivers dependable uptime and reduces motor wear, making it ideal for motor feeders in industrial panels. Application: suitable for manufacturing environments where rapid, predictable trips are essential. DC shunt trip capability at 24/48 V DC enables remote or safety interlock shutdown in automation lines. This feature minimizes risk during maintenance or emergency events, improving worker safety and process resilience. Application: useful for conveyors, presses, and automated lines requiring quick disconnection. Bolt-on mounting supports fast installation and straightforward retrofits. Business impact: reduces field labor costs and panel downtime while enabling seamless integration with standard enclosures. Application: retrofit projects and new builds in control cabinets. HACR rated with CSA UL listing provides NEC-aligned safety and reliability. Business impact: simplifies compliance and reduces approver queries during audits. Application: HVAC control circuits and building automation panels in commercial and industrial settings. Compact footprint (5 in depth x 3 in width x 1 in height) and 0.5 lb weight optimize panel space. Business impact: enables denser, more organized control panels and easier handling during installation. Application: space-constrained electrical cabinets and automation enclosures. Rated for 240 V operation with 70 A protection and 10 kAIC interrupt capacity, it delivers robust protection for general purpose machinery. Business impact: supports scalable protection across machinery, pumps, and process lines. Application: three‑phase machinery feeders in manufacturing facilities.
