Special features
24/48V/Vdc shunt trip
Three-pole, 100 A rating with a 22 kAIC interrupt capability provides fast, selective protection for motor feeders and power distribution in industrial panels. This combination reduces conductor stress, limits arc flash exposure, and improves uptime by avoiding unnecessary trips downstream. Application: motor control centers, pumps, and processing lines that demand dependable protection with minimal downtime. Thermally-magnetic trip combines inverse-time thermal protection with instantaneous magnetic trip at overload, delivering reliable protection for diverse load profiles and startup surges while minimizing nuisance trips during normal operation. Application: conveyors, blowers, and extrusion lines where inrush currents are common. Shunt trip capability (12-48 Vac/dc; 24/48 Vdc shunt trip option) enables remote shutdown for safety interlocks and emergency stop schemes, reducing reliance on additional control relays. Application: robotic cells, presses, and hazardous-material handling areas. Plug-on mounting simplifies panel integration and reduces installation time, aligning with Eaton Quicklag families for modularity and serviceability. Application: control cabinets and modular switchgear in new builds or upgrades. Compliance and physical specs include HACR rated; CSA Certified and UL Listed; dimensions 3.8 in L, 4.8 in H, 2.2 in W, weight 0.7 lb—supporting space-constrained panels and easy field retrofits.
