Industrial U6C3400 400A 600 V Circuit Breaker

Industrial U6C3400 400A 600 V Circuit Breaker — part number U6C3400 — is engineered for heavy-duty protection in demanding electrical systems. This high-current breaker is designed to interrupt fault currents safely and quickly, safeguarding equipment and people in industrial environments.

Key specifications

• Current rating: 400 A
• Voltage rating: 600 V
• Part number: U6C3400
• Type: Industrial circuit breaker

Why this breaker stands out

Where standard residential breakers falter under heavy load, the U6C3400 is built for continuous service in panels, switchgear, and motor control centers. It provides robust protection for large feeders and machinery, reducing the risk of cascading faults and unplanned downtime. Its industrial-grade construction supports repeated operation in environments with vibration, dust, and temperature variation common on manufacturing floors.

Ideal for

• Feeder protection in distribution panels and motor control centers
• Motor control circuits for large equipment such as lathes, presses, and conveyors
• Power distribution in manufacturing facilities, processing plants, and HVAC substations

Practical considerations and how it helps you

With a 600 V rating, this breaker is suited for medium- to high-voltage industrial circuits. It helps prevent equipment damage from overloads and short circuits by isolating the circuit when faults occur. Compared to smaller, lower-current breakers, it supports higher-capacity systems without sacrificing safety.

Tips for integration

• Verify compatibility with your panel or switchgear, including mounting style and bus connections
• Consult system diagrams to ensure the 400 A rating aligns with your feeder or motor load
• Maintain proper electrical clearances and follow lockout/tagout procedures during maintenance
• Schedule periodic inspection of trip mechanisms and insulation integrity for reliability

Investing in the Industrial U6C3400 400A 600 V Circuit Breaker means choosing a dependable line of defense for critical loads. Keep production lines moving and equipment protected with a breaker designed for the realities of modern industry.
