Compatibility and installation notes

Important: Confirm fit and ratings before ordering. The part number KL3125L is the best reference for compatibility with your panel or equipment. When replacing, ensure the circuit is de‑energized and the system voltage and three‑phase configuration match the 600V, 3‑pole specifications. If in doubt, consult the panel’s documentation and a licensed electrician to validate mounting and wiring compatibility.

Maintenance and safety considerations

• Always follow lockout/tagout procedures and disconnect power before any replacement work.
• Inspect the surrounding panel and wiring for signs of wear, overheating, or corrosion during replacement planning.
• Handle and install with appropriate PPE and according to local electrical codes to maintain personnel safety and system integrity.

Equip your distribution and protection strategy with KL3125L to ensure reliable 3‑phase protection at up to 600V, backed by a clear compatibility reference that simplifies sourcing and installation.
