What makes the CN3B800 stand out

Unlike generic replacements, this CN3B800 is a precise fit for panels and switchgear that require the CN3B800 form factor. The 3-pole configuration ensures robust control of 3-phase power, providing coordinated protection across all phases. The 100kA interrupting capacity gives you confidence in fault conditions, helping to minimize damage and downtime. The bolt-on design supports straightforward installation, reducing service time and ensuring a secure, lasting connection in compatible enclosures.

Ideal use cases

• Maintenance projects where existing equipment must be replaced with an exact specifier
• Retrofits in industrial facilities upgrading distribution panels or switchgear
• Spare-parts stock for service teams performing proactive replacements
• New installations in 600V systems that require a high-current, three-phase breaker

Compatibility and installation considerations

Before ordering, verify that your equipment matches the CN3B800 specs. The part number CN3B800 is the best reference for compatibility, ensuring proper mounting, electrical connection, and protection characteristics for your panel. If you’re replacing an existing breaker, confirm both the fit and the ratings align with your system’s voltage, current, and fault-current requirements.

Why this matters for your operation

Choosing the correct circuit breaker is about more than matching amperage. The CN3B800 delivers a reliable, three-phase protection solution designed to integrate with standard 600V distribution schemes. It helps safeguard critical machinery, reduces the risk of extended outages, and supports orderly maintenance cycles by providing a predictable, compatible replacement option when service is required.

Compatibility note: Confirm fit and ratings before ordering. The CN3B800 part number is the best reference for compatibility.
