FAQs

MDLB2450 is designed for Eaton Series C MDL-frame installations and two-pole configurations. It fits standard Series C MCCB footprints, enabling straightforward retrofits or new builds without extensive panel redesign. Always verify lug type and terminal torque per Eaton application notes for optimal performance.
Key specs include a 450 A amperage rating, 65 kAIC at 240 V, and 50 kAIC at 480 V, with a 50/60 Hz rating. The device uses fixed thermal-magnetic trip (T186) and is a two-pole MDLB series MCCB, designed to protect above-average, high-energy industrial circuits.
Ideal for motor control centers, switchgear, and control panels in industrial facilities. The 65 kAIC/50 kAIC ratings support robust fault protection for feeders and motor circuits, while the MDL frame facilitates integration into existing Series C protection schemes.
MDLB2450 is UL Listed, ensuring compliance with recognized safety standards. While the dataset lists UL Listed, users should confirm regional regulatory requirements (such as CE in Europe) through local standards documentation before deployment in non-US markets.
Warranty follows Eaton policy 25-000, offering one year from installation or eighteen months from shipment, whichever comes first. Regular inspection of terminal connections and thermal-magnetic trip function testing per maintenance schedules helps sustain protection performance and minimize unplanned downtime.
