Implementation of arc flash mitigating solutions at industrial manufacturing facilities
Feature → Business Impact → Application: The MDL frame provides a robust 800 A rating, enabling protection of heavy motor loads without multiple devices, reducing panel footprint and total cost of ownership in motor control centers. This improves uptime and reduces logistics complexity in manufacturing environments requiring reliable high-current protection. Feature → Business Impact → Application: T172 trip type with 65 kAIC at 240 VAC and 50 kAIC at 480 VAC delivers precise short-circuit interruption, minimizing arc energy and equipment damage, ideal for high-demand industrial feeders and critical power circuits. Feature → Business Impact → Application: Undervoltage release at 110–125 Vdc (rear with left pigtail) provides secure tripping during undervoltage events, enhancing personnel safety and preventing nuisance trips in variable-load plants. Feature → Business Impact → Application: Optional line/load terminals and 2A-2B rear auxiliary switch enable straightforward installation, status monitoring, and seamless integration into existing Series C MCCB ecosystems. Feature → Business Impact → Application: UL Listed certification and Series C compatibility ensure compliance with safety standards while supporting straightforward procurement and maintenance in industrial facilities. Feature → Business Impact → Application: Compact 0.01 in footprint variations (length, height, width, weight) and catalog notes for T600MA1 terminals simplify retrofits and replacement, reducing downtime during upgrades in evolving electrical distributions.

FAQs
Yes. This model uses the Series C MDL frame and supports optional line/load terminals, making it suitable for integration into existing Eaton Series C MCCB ecosystems. Its three-pole configuration and 800 A rating align with common motor control center and feeder panel designs, simplifying upgrades and retrofits without compromising protective coordination.
Key specs include an 800 A amp rating, 600 Vac / 250 Vdc voltage rating, and an interrupt rating of 50 kAIC at 480 VAC and 65 kAIC at 240 VAC. The trip type is T172, suitable for reliable short-circuit protection across industrial loads. These figures support safe operation and minimized equipment damage under fault conditions.
Series C MDL MCCBs are well-suited for motor control centers, feeder panels, and critical power distribution in manufacturing facilities. The combination of high current protection, adjustable terminals, and compatibility with Series C accessories enables streamlined protection strategies for large electrical systems with variable loads.
The undervoltage release operates at 110–125 Vdc with a rear left-side pigtail, ensuring the breaker trips when supply voltage drops unexpectedly. This protects equipment from undervoltage-induced faults and prevents unsafe energization of circuits during startup or brownouts, enhancing both personnel safety and equipment reliability.
The product is UL Listed and covered by Eaton’s standard warranty policy (25-000), offering one year from installation or eighteen months from shipment, whichever occurs first. Technical support and documentation are available through Eaton’s application notes and datasheets to assist with installation, testing, and maintenance.
