Feature → Business Impact → Application: The MDL3800WKA1201S0101 is rated at 800 A with fixed thermal and magnetic trip (T186), delivering dependable fault isolation in high-load machines. This translates to reduced arc flash risk and lower downtime when motors and feeders demand rapid interruption in fault conditions, ideal for heavy manufacturing lines and process automation. Application: Use in main feeders and control panels where high short-circuit withstand is required, supporting uptime targets while meeting industry protection standards. Feature → Business Impact → Application: Three-pole MDL frame with 600 Vac and 250 Vdc ratings provides broad compatibility across alternating and DC-controlled loads, enabling safer power distribution in mixed-voltage environments common in packaging, material handling, and robotics systems. Feature → Business Impact → Application: Auxiliary switch (2A-2B) on the same side with right-side pigtail simplifies signaling and interlocking schemes, reducing wiring complexity and installation time in panel interiors. Feature → Business Impact → Application: Shunt trip option (12-24 Vac/dc on same side with left pigtail) supports remote de-energization and safety interlocks for machine guarding and remote shutdown scenarios in hazardous production areas. Feature → Business Impact → Application: Terminals without terminals design streamlines integration with busbars or dedicated lug schemes, enabling cleaner panel layouts and faster field assembly in new builds or retrofits. Feature → Business Impact → Application: UL Listed certification provides a foundation for compliance with safety and design standards, helping procurements meet regulatory requirements while ensuring reliable performance during peak demand. Feature → Business Impact → Application: Series C, MDL frame and fixed trip configuration align with established MCCB portfolios, easing lifecycle management, spares planning, and service center support for large industrial facilities.

FAQs
This breaker uses the Series C MDL frame designed for molded case protection common in Series C panels. It is a three-pole device with no terminals included, so installation typically requires compatible busbars or lug assemblies. Verify panel compatibility with your MCCB catalog and ensure correct busbar sizing and mounting hardware are used for clean, reliable connections.
Key specs include an 800 A amperage rating, 600 Vac and 250 Vdc voltage ratings, a fixed thermal/magnetic trip (T186), and a 65 kAIC interrupt rating at 240 Vac (50 kAIC at 480 Vac). The unit is three-pole, with series MDL frame and auxiliary/shunt options available to tailor fast protective actions to your system.
The auxiliary switch (2A-2B on the right) and shunt trip (12-24 Vac/dc on the left) are designed to simplify remote signaling and automatic shutdowns. These features enable interlock and remote control scenarios, reducing manual intervention and improving safety in production lines where automated de-energization is required during fault or maintenance events.
Yes, the device is UL Listed, ensuring compliance with recognized safety standards for electrical protection equipment. While UL coverage is explicit in the data, users should confirm alignment with regional CE, IP, or other regulatory requirements to match local codes and project specifications.
By providing fast, reliable trip performance and modular options for signaling and interlocking, this MCCB minimizes unplanned downtime and improves fault containment. Its compatibility with Series C hardware supports streamlined spare parts management and longer service intervals, delivering lower maintenance costs and faster return on investment for high-demand production environments.
