Square D | KCF34080 | Circuit Breaker | 80A | 3-Pole | 480V

Meet the Square D KCF34080 Circuit Breaker — an 80-amp, 3-pole protective device engineered for 480-volt three-phase systems. Designed for reliability in maintenance, retrofit, and replacement scenarios where exact specifications matter, this unit safeguards your industrial power distribution from overloads and faults, helping keep production lines humming and downtime to a minimum.

The KCF34080 identifier is your best reference for compatibility. Before ordering, confirm fit and ratings against your panel requirements to avoid mismatches.

Key specifications

• Amperage: 80 A
• Poles: 3-Pole
• Voltage: 480 V

Why this 3-Pole, 480V breaker matters

In a three-phase 480V environment, a 3-pole breaker like the KCF34080 provides coordinated protection across all live lines. With an 80A rating, it safeguards conductors and connected equipment from overloads and short circuits, helping prevent costly downtime and equipment damage. This selection is especially relevant for panels that distribute heavy loads across motors, drives, and processing equipment.

Ideal use cases

• Maintenance and retrofit projects requiring an exact match to the KCF34080 specifications
• Replacement in industrial control panels and switchgear operating on 480V three-phase power
• Upgrades in manufacturing lines that demand reliable, predictable trip characteristics for downstream protections

What problems it solves

• Overload protection for conductors and connected equipment in 480V systems
• Short-circuit protection to limit fault current and reduce damage risk
• Operational stability by ensuring consistent protection aligned with your protection coordination plan

How to ensure a perfect fit

Because reliability hinges on correct compatibility, rely on the part number KCF34080 as the primary reference. Check your panel’s documentation to verify that three-pole, 480V protection is supported and that the amperage matches your circuit requirements.

Practical tips and best practices

• Match the breaker’s amp rating, pole count, and voltage to your panel’s labeling and upstream protection
• Consult a qualified electrician for installation to ensure proper mounting and safe operation
• Keep a copy of the panel schedule and the replacement part’s documentation for future maintenance and audits
