Eaton MDL3400W Molded Case Circuit Breaker - UL Listed

Three-pole MDL frame design provides a compact, integrated protection module for motor control centers. This arrangement simplifies panel layouts, improves coordination, and reduces assembly time, enabling faster commissioning in industrial machines and line-side power distribution. Applications include process automation panels and machine cells where space is at a premium and reliability is non-negotiable. High interrupt ratings enable reliable fault interruption without nuisance tripping in demanding loads. That translates to reduced downtime and safer shutdown sequences in manufacturing lines. Suitable for 240 Vac and 480 Vac systems in plant-wide distribution. Shunt-trip option allows remote protection in critical lines, facilitating quick isolation during startup or fault events. Incorporating the left-pigtail shunt simplifies wiring and keeps control integration straightforward. Terminals are not included on the unit, which allows a flexible field wiring approach and compatibility with user-specified bus bars or lugs. This supports rapid retrofit into legacy panels while preserving protection performance. Designed for 50 to 60 Hz operation and broad voltage ratings (600 Vac, 250 Vdc) to support diverse plant electrical systems. A 400 A ampere rating matches typical motor and feeder protection needs, delivering dependable protection for heavy loads.
