ITE | CF3B070 | Circuit Breaker | 3-Pole | Bolt-On

The ITE CF3B070 circuit breaker is a reliable, 3-pole bolt-on solution designed for maintenance, retrofit, and replacement projects where exact specifications matter. Built to align with compatible ITE CF3B frames, this unit helps you keep electrical systems protected without the guesswork of cross-referencing incompatible parts.

Key advantages of the ITE CF3B070

• Three-Pole Bolt-On Design: Secure, high-integrity mounting that resists loosening in demanding environments, ensuring consistent protection across all phases.
• Direct Fit for Compatible Panels: Formulated to serve as a precise replacement or retrofit for panels that accept CF3B-series breakers, minimizing installation downtime.
• Clear Compatibility Reference: The part number CF3B070 is your best reference for compatibility—always verify against your panel’s labeling and datasheet before ordering.
• Maintenance and Retrofit Ready: Ideal for refreshing aging electrical distribution or upgrading an older system to restore protection without replacing the entire panel.
• Emphasis on Proper Ratings: Before ordering, confirm the current rating, voltage rating, and interrupting capacity match your system requirements as listed on your panel label or system documentation.

Who benefits from the CF3B070

• Maintenance teams performing routine service or replacements in industrial, commercial, and utility-adjacent environments.
• Project engineers planning retrofits or panel upgrades that require a bolt-on, 3-pole protective device with known OEM reference.
• Facilities managers maintaining spare parts inventories with exact-part compatibility to minimize downtime during servicing.

Use cases and scenarios

• Replacing a failed 3-pole breaker in an older distribution panel where bolt-on hardware is standard.
• Upgrading equipment protection in retrofit projects that retain CF3B-series frame compatibility.
• Stocking a reliable, ready-to-deploy unit for routine maintenance cycles in manufacturing or processing facilities.

Practical tips for a smooth fit

• Double-check the panel label and datasheet to ensure CF3B070 aligns with the intended frame size and mounting method.
• Verify electrical ratings (current, voltage, and interrupting capacity) match the system requirements before installation.
• Prepare a clean workspace and have the appropriate mounting hardware on hand to support a secure bolt-on installation.
• Keep the part number documented in your spare parts directory to streamline future maintenance and replacements.

Why this matters in the real world

Electrical protection is only as effective as its compatibility. The CF3B070’s 3-pole bolt-on design provides a dependable, field-proven solution for scenarios where exact framing and bolt-on mounting are required. By choosing the ITE CF3B070 and relying on the part-number-based compatibility approach, you reduce the risk of mismatched components that can lead to protection gaps or unnecessary downtime.

Bottom line

When you need a precise, bolt-on 3-pole breaker that supports maintenance, retrofit, and replacement workflows, the ITE CF3B070 delivers a straightforward, compatible choice. Use the CF3B070 part number as your primary compatibility reference, and verify panel ratings to ensure a seamless, safe, and efficient upgrade or service.
