Industrial K3225N 225A 3-Pole 600 V Circuit Breaker

Designed for demanding industrial environments, the Industrial K3225N 225A 3-Pole 600 V Circuit Breaker delivers reliable protection for three-phase power systems. With a robust 225 A current rating and a precise Part Number K3225N, it’s built to safeguard feeders and machinery while simplifying maintenance and replacements in busy switchgear and control panels.

Key capabilities that drive uptime

• 225 A current rating provides strong overload protection for heavy-duty feeders and motor circuits, helping prevent equipment damage and unplanned downtime.
• 3-Pole configuration ensures balanced protection across all three phases, promoting stable operation in three-phase systems and reducing the risk of phase imbalance.
• 600 V voltage rating makes it suitable for standard industrial distribution environments, handling typical plant startup currents and inrush conditions common in manufacturing and processing settings.
• Industrial-grade reliability designed for continuous service in panel boards, switchgear, and control cabinets, with straightforward replacement through the familiar K3225N footprint.

Ideal applications

• Protection for three-phase motors and conveyors in manufacturing plants
• Main or feeder protection in industrial distribution panels and motor control centers
• Upgrading aging or obsolete breakers in high-demand environments like metal fabrication, packaging lines, and process facilities
• Residential-scale or commercial-industrial hybrids where robust three-phase protection is required

Why choose the K3225N in your electrical system

• Accurate, replaceable part number ensures you’re sourcing the exact component designed for your setup
• Three-pole protection provides comprehensive, synchronized shutdown across all phases, reducing fault propagation risks
• 600 V rating aligns with typical industrial distribution standards, supporting safer, more stable operation of equipment and circuits
• Clear, unambiguous specifications—225 A, 3 poles, 600 V—facilitate quick sizing and procurement decisions

Practical considerations for installation and maintenance

• Verify compatibility with your panel enclosure and busbar arrangement to ensure seamless installation
• Match the breaker’s 225 A rating to the protected circuit’s amperage and the connected equipment’s start-up demands
• Follow the manufacturer’s installation guidelines for mounting orientation, electrical clearances, and safety practices
• Keep spare K3225N units on hand for rapid replacement and reduced downtime during maintenance windows
