Eaton KG3400W Engine MCCB - UL Listed

Feature: The KG3400W delivers a 400 A amperage rating, enabling precise overload protection for engine-driven generators and large standby systems. This targeted protection minimizes nuisance trips during startup and rapid load ramps, reducing wear on contacts and downtime. Application: Suited for three-pole, 60 Hz installations at 600 Vac in industrial facilities and backup power projects. Feature: 600 Vac voltage rating and 60 Hz compatibility ensure compatibility with standard industrial electrical systems. This alignment simplifies integration with existing gensets and distribution panels, reducing engineering time and field rewiring. Application: Fits typical engine-generator sets and commercial standby power architectures. Feature: High short-circuit interrupt ratings—18 kAIC at 240 Vac and 14 kAIC at 480 Vac—provide robust fault protection. This protects transformers, generators, and downstream equipment from damage during transient faults. Application: Critical for systems with high fault currents, such as data centers, hospitals, and manufacturing lines. Feature: Trip type T268 and the complete KG frame enable fast, selective tripping with reverse-feed capability. This improves coordination with upstream protection schemes and avoids unnecessary outages in generator-parallel configurations. Application: Essential for engine-generator compartments and reverse-feed installations in standby power configurations. Feature: Dimensions and weight (12.25 in L x 6.9 in H x 6.75 in W; 10 lb) support compact, easy-to-install protection solutions. Reduces enclosure footprint and installation time, lowering total cost of ownership. Application: Suitable for compact switchgear, generator enclosures, and panel layouts in industrial plants. Feature: Generator rating ranges—144 kVA/116 kW at 240 Vac, 289 kVA/231 kW at 480 Vac, and 361 kVA/289 kW at 600 Vac—allow precise sizing with engine dynamics. This alignment enables efficient protection coordination and future scalability for multi-voltage engine-generator sets. Application: Used in industrial facilities and utility-scale backup systems that require adaptable protection across voltages.
