FAQs
MDL3700 is a three‑pole MDL frame MCCB designed for Series C protection in standard 3‑phase panels. Ensure the panel accommodates an 18.25 in depth and 10.75 in width footprint, and confirm the bus configuration matches a fixed thermal/magnetic trip device. Refer to the Series C catalog and datasheet for mounting clearances and accessory compatibility.
MDL3700 provides a fixed magnetic trip with a 65 kAIC rating at 240 Vac and 50 kAIC at 480 Vac, plus a 700 A amperage rating and voltage ratings of 600 Vac / 250 Vdc. These specs ensure fast fault clearing and robust protection for high‑inrush loads and motor circuits typical in industrial environments.
Yes. With Series C MDL framing and a three‑pole design, MDL3700 is well suited for motor protection in demanding applications such as conveyors, pumps, and presses. The UL Listed certification supports safety compliance, while the fixed trip characteristics provide predictable protection against overloads and short circuits.
MDL3700 carries Eaton’s policy of one year from installation or eighteen months from shipment, whichever occurs first. This warranty, along with Eaton’s service centers and documentation, supports ongoing reliability, spare parts availability, and technical assistance for field installations and retrofits.
Eaton provides application notes, installation guides, and series C datasheets. Key materials include the Series C MCCB catalog, time-current curves, and terminal/tap rules resources, helping engineers ensure proper termination, safe installation, and regulatory compliance in control panels and motor control centers.
