HJL634350 | Circuit Breaker | 350A | 3-Pole | 600V

The HJL634350 circuit breaker is an industrial-grade protective device designed for demanding 3-phase 600V electrical systems. Ideal for maintenance, retrofit, and replacement projects where exact specifications matter, this unit keeps your power distribution safe and reliable.

Key specifications

• Amperage: 350 A
• Poles: 3-Pole
• Voltage: 600 V

Why this 3-pole 350A breaker matters

With a 3-pole design, it interrupts all three phases simultaneously, minimizing the risk of unbalanced loads and improving system protection. The 350 A rating is suitable for mid-to-high current branches within industrial panels, feeders, and assembly lines, helping to prevent electrical faults from escalating into outages.

Best-use scenarios

• Maintenance of existing 600V distribution panels that require precise part compatibility.
• Retrofits where your equipment relies on a standard 3-phase protection strategy.
• Replacement parts for OEM-installed panels, ensuring continuity of protection while you upgrade other components.

Note: Confirm fit and ratings before ordering. The part number is the most reliable reference for compatibility. Use HJL634350 when your system specifies a 3-pole, 350A, 600V breaker to ensure seamless integration and regulatory compliance.

Installation and reliability tips

• Have a qualified electrician verify the panel rating and bus configuration before installation.
• Prepare to coordinate with your panel's labeling and safety procedures; de-energize the circuit before replacement.
• Keep a record of the part number (HJL634350) for future maintenance and ordering consistency.
