Eaton 6MDSL-MB1200 Cable Limiter - IEEE C37.41
Part Number: 6MDSL-MB1200
Quick Summary
The Eaton 6MDSL-MB1200 cable limiter protects feeders by interrupting fault currents in low-voltage power circuits. Engineers often struggle with nuisance fuse trips and protection miscoordination, which this device helps minimize. It carries IEEE Std. C37.41 certification and supports 600 V systems with a 1200 A rating and 200 kAIC interrupt capacity. Designed for the Bussmann series, it offers installation simplicity, predictable protection, and long-term cost savings across industrial power distribution. In addition, the compact 5.75 in length, 2.88 in width, and 4 lb weight help minimize panel footprint while maintaining robust protection. This aligns with modern safety and reliability goals for facilities upgrading electrical infrastructure.

FAQs
Install the 6MDSL-MB1200 using the catalog number 6MDSL-MB1200 in accordance with Eaton's installation guidelines. Ensure the circuit is de-energized, verify 600 V rating compatibility, and position the device to minimize conductor routing. The unit’s compact 5.75 in length helps fit into tighter panels, while the 4 lb weight aids handling during assembly. Always validate bus protection coordination with adjacent fuses and breakers.
The device is rated for 1200 A continuous amperage, 200 kAIC interrupt capacity, and a 600 V operating voltage. It is designed as a low voltage current limiter fuse (MDSL type) and carries IEEE Std. C37.41 certification, ensuring compatibility with standard protection schemes in industrial power distribution.
Yes. The 6MDSL-MB1200 is specifically rated for 600 V systems and provides high interrupt capacity (200 kAIC) to handle large fault currents. Its MDSL low voltage current limiter design helps limit fault energy and protect cabling, making it suitable for industrial feeders, motor circuits, and switchgear protection in 600 V architectures.
The product carries IEEE Std. C37.41 certification, which aligns it with established protective standards for circuit breakers and fuses in high-energy fault scenarios. This certification supports compliance, safer integration with existing protection schemes, and easier due diligence during audits.
Eaton provides a one-year warranty from the date of installation or eighteen months from the date of shipment, whichever comes first. This coverage, combined with Eaton’s service policy, provides procurement confidence and ongoing support for installation, replacement, and preventive maintenance activities.
