FAQs
MDL3500WA08S04 is a three-pole MDL frame MCCB designed for Series C panels. It is specified as without terminals, so you will need to select compatible lugs or termination kits and wire harnesses. The unit supports a shunt trip (12-24 Vac/dc on the left side) and an auxiliary switch (1A-1B on the right terminal), which facilitates remote control and status signaling in panel builds.
This MCCB is rated for 500 A, 600 Vac and 250 Vdc, with an interrupt rating of 65 kAIC at 240 Vac and 50 kAIC at 480 Vac. It operates at 50 to 60 Hz and uses a T186 trip type within the Series C MDL frame, making it suitable for high-current feeders and motor circuits in industrial environments.
Yes. The 3-pole MDL frame with fixed thermal and magnetic trips provides reliable motor protection, reducing nuisance trips and enabling predictable motor start/stop sequences. The 65 kAIC at 240 Vac rating supports fault current handling in motors and feeders common in manufacturing plants.
The MDL3500WA08S04 is UL Listed, confirming compliance with safety standards for North American electrical installations. Eaton provides a warranty under policy 25-000, offering one year from the date of installation or 18 months from shipment, whichever occurs first.
With a Series C MDL design, fixed trips, and selectable remote features (shunt trip and auxiliary switch), installation and commissioning are streamlined, reducing maintenance downtime. The UL Listed certification and robust fault-current ratings help minimize risk and warranty claims, delivering lower total cost of ownership over the equipment lifecycle.
