Eaton MDLB2300 Complete MCCB - Series C UL Listed

Two-pole, 300 A protection delivers robust overcurrent protection for motor-control circuits and critical power feeds within industrial panels. This design reduces nuisance trips, minimizes unplanned downtime, and extends motor life in demanding environments. Typical applications include motor starters, switchgear, panelboards, and distribution assemblies in manufacturing plants. Fixed thermal and magnetic trip type T186 provides predictable, coordinated protection with downstream devices. This improves selectivity, minimizes outages, and protects drive trains from fault currents. It is well suited for conveyors, pumps, and process equipment where reliable tripping is essential. 65 kAIC at 240 Vac and 50 kAIC at 480 Vac interrupt ratings tolerate high fault currents without nuisance trips. That resilience translates to safer switchgear and reduced downtime during faults. Facilities with high short-circuit currents in feeders and distribution panels benefit from this margin. MDLB is a complete MDL-frame solution within the Series C family, enabling straightforward field installation and consistent protection. This alignment simplifies maintenance, reduces stocking errors, and speeds panel upgrades. Engineers can rely on compatible lugs, terminals, and accessories from Eaton's ecosystem to streamline projects. Global compatibility is supported by 50/60 Hz operation, enabling deployment across international sites. This reduces design complexity and procurement fragmentation for multi-site OEMs. The product is UL Listed, reinforcing safety compliance across markets. Reliability and service are enhanced by Eaton's documented warranty policy, providing coverage from installation or shipment timelines. This reduces lifecycle risk and supports total cost of ownership for protective devices.
