• Motor feeders and three-phase distribution circuits in manufacturing, processing, or HVAC systems

Fitment & compatibility

Before ordering, verify fit and ratings against your panel or enclosure. The CLM3B400 part number is the most reliable reference for compatibility, helping you avoid mismatches in mounting pattern or electrical ratings. If you’re updating an aging panel, cross-check the panel’s data sheet or contact the manufacturer with the CLM3B400 reference to ensure seamless integration.

Installation and practical tips

• Power down the system and follow all safety procedures before replacement or installation.
• Use the panel’s documented bolt-on method to secure the breaker firmly; ensure all mounting bolts are tightened per your enclosure’s guidelines.
• Inspect conductors and bus connections for cleanliness and integrity during replacement to prevent poor contact.
• After installation, test the circuit behavior in a controlled manner to confirm proper protection and operation.
