Why this K3090 matters

When refreshing an existing installation, matching the original part number is the fastest path to seamless compatibility. The K3090’s 3‑pole, 90A rating up to 600V makes it suitable for many three‑phase panels and switchgear that require a direct like‑for‑like replacement. The part number is the best reference for compatibility, helping you avoid mismatched trip characteristics or mounting footprints and ensuring a smooth swap in your equipment.

Ideal use cases

• Maintenance on industrial feeders and motor circuits up to 600V
• Retrofit projects where a like‑for‑like three‑phase breaker is required
• Replacement of worn or failed breakers in service panels and control gear

Practical guidance for a successful fit

Before ordering, confirm that your system is three‑phase, operates at up to 600V, and requires a 90A rating. The K3090 part number serves as the strongest reference for compatibility, ensuring the correct form factor, mounting, and electrical characteristics match your existing equipment. If your documentation lists K3090, this breaker is the right match.

Installation and safety

Install by qualified personnel following established safety procedures. Verify that the panel’s bus and mounting arrangement accommodate a 3‑pole, 600V device and that the installation adheres to all applicable electrical codes and standards.
