Thermal-magnetic protection provides both overload and short-circuit interrupt capability, delivering a reliable safeguard for critical load circuits. Business impact: reduces nuisance trips and enhances system availability in daily operations. Application: protects 30 A circuits in distribution panels and Type ECC enclosures with a compact, two-pole configuration. The 10 kAIC interrupt rating further minimizes fault energy, safeguarding wiring and equipment during high-energy faults. Application: suitable for demanding industrial environments where quick fault clearance is essential. The unit accepts #4-4/0 AWG Cu/Al conductors, offering versatile wiring options and easier field assembly. Business impact: lowers installation time and inventory complexity while supporting diverse feeder configurations. Application: common in motor control centers and light industrial panels with mixed conductor types. Its UL 489 certification signals regulatory compliance and robust safety expectations, reducing supplier risk for integrators. Application: standard compliance in North American installations and OEM panel builds. The physical footprint—3.9 in L × 4.8 in H × 2.2 in W, 0.55 lb weight—contributes to a smaller panel footprint and easier handling. Business impact: saves enclosure space and simplifies transport and installation. Application: ideal for compact control panels where space is at a premium. Finally, Type ECC Enclosure compatibility streamlines BOMs and field service, enabling consistent performance across Eaton’s protection family. Application: reduces design complexity and expedites commissioning in commercial and light industrial projects.
