Industry Applications
The Schneider JDL36225 is ideal for upgrading legacy panelboards and switchgear in manufacturing plants, commercial buildings, and utility substations. Its compact J-frame design fits into existing unit mount configurations, simplifying retrofits. Use this breaker to protect motor control centers, lighting panels, and feeder circuits where reliable thermal-magnetic trip characteristics are required.
Installation & Setup
Mount the JDL36225 on a standard panel using the provided mounting holes. Ensure the line and load lugs are torqued to manufacturer specifications for the 350 KCMIL wire size. Verify the breaker is in the OFF position before connecting conductors. Adjust the continuous current rating dial to 80% if needed for your application. Always follow local electrical codes and safety practices.
Maintenance & Reliability
Inspect the Schneider JDL36225 quarterly for signs of overheating, such as discolored lugs or insulation. Exercise the toggle mechanism annually to ensure free movement. Keep the breaker clean and dry; avoid exposure to corrosive atmospheres. The thermal-magnetic design provides long service life with minimal maintenance, reducing total cost of ownership.
Selection Guide & Purchasing Advice
Before ordering, confirm your system voltage (600 VAC max), continuous load current (225 A), and interrupting capacity requirements (14 kA).
