Schneider Electric JDL36225 PowerPact J 225A 3-Pole Molded Case Circuit Breaker

Technical Specifications Breakdown

Key parameters for the JDL36225 are listed below for quick reference:

Industry Applications for the PowerPact J-Frame Breaker

Industrial facilities rely on the JDL36225 for motor branch circuit protection and feeder circuits. Its 225A rating and 14kA interrupting capacity make it suitable for manufacturing lines, HVAC systems, and pump stations. The thermal-magnetic trip provides instantaneous response to short circuits while handling sustained overloads, reducing unplanned downtime.

Installation and Setup Guidance

Mount the JDL36225 on a panel using the provided J-Frame base. Ensure the line and load copper lugs are torqued to manufacturer specifications for 350 KCMIL wire. Verify the continuous current rating of 80% aligns with your load calculations. Always de-energize the system before installation.

Maintenance and Reliability

Inspect the breaker quarterly for signs of heat stress or corrosion on lugs. Keep the enclosure clean and dry. The toggle actuator should move freely; if resistance is felt, replace the unit. No internal adjustments are required for the thermal-magnetic trip mechanism.

Selection Guide and Purchasing Advice

When selecting a molded case circuit breaker, match the voltage and current to your system. For availability and lifecycle status, contact AutoDCSTech before ordering to ensure stock and support.

Troubleshooting and Common Issues

If the breaker trips frequently, check for overload conditions or loose connections. Verify the load does not exceed 80% continuous rating. For nuisance tripping, inspect for harmonic currents or faulty downstream equipment. Always consult a qualified electrician for diagnostics.
