Eaton MDL3800A01 Molded Case Circuit Breaker - UL Listed

Part Number: MDL3800A01
Manufacturer
Eaton
Part number
MDL3800A01

Quick Summary

MDL3800A01 Molded Case Circuit Breaker protects industrial power distribution by interrupting fault currents in panels. Nuisance trips and unplanned downtime challenge maintenance teams, but a fixed thermal-magnetic trip reduces false trips while delivering reliable protection. UL Listed certification confirms safety compliance, and the Series C MDL frame ensures compatibility with common protection schemes across machines and panels. This three-pole device supports up to 800 A at 600 Vac or 250 Vdc, with a 65 kAIC interrupt rating at 240 Vac, making it suitable for medium- to high-current applications. The left-side 1A-1B auxiliary switch simplifies control wiring, and documented time-current curves aid accurate coordination. In practice, this MCCB streamlines installation, lowers operating risk, and supports scalable automation architectures in manufacturing environments.
