What makes it stand out
In demanding environments, a three-pole design helps protect three-phase loads more evenly, coordinating protection across all phases. With a 400 A rating, this breaker is well-suited for large motors, compressors, and heavy feeders common in industrial facilities. The 600 V rating supports typical low-to-medium voltage distribution used in commercial and light industrial settings, providing a timely response to overloads and short circuits while enabling safe power restoration after trips.
Installation and compatibility
This unit is intended for use where maintenance, retrofit, or replacement is required, and it pairs with panels and equipment that match the LCF36400 specifications. To minimize downtime and ensure safe operation, confirm fit and ratings before ordering—the part number is your best reference for compatibility.
Who it's ideal for
Facilities that rely on robust three-phase power distribution, including manufacturing lines, large capacity feeders, commercial building service panels, and retrofit projects seeking to upgrade or replace aging protection devices.
Practical tips
- Keep the exact part number (LCF36400) handy when surveying replacement needs to ensure a perfect match.
- Verify the system voltage and pole configuration in your panel before purchasing—this unit is 3-pole and 600V rated.
- Plan for a smooth swap by reviewing the panel's bus configuration and mounting provisions against the breaker’s connection points.
