Product description
Shipping

Meet the KL3300L, a rugged industrial circuit breaker engineered for reliability in maintenance, retrofit, and replacement projects where exact specifications are non-negotiable. This 3-Pole, 600V device protects three-phase electrical systems by interrupting fault currents before damage spreads, keeping equipment and personnel safer.

Key specifications

  • Amperage: 300A
  • Poles: 3-Pole
  • Voltage: 600V

Why the KL3300L stands out

Designed for installers who demand a precise match to existing panels, the KL3300L offers compatibility guaranteed by the part number itself. Whether you’re performing routine maintenance, retrofitting aging infrastructure, or replacing a failed unit, this breaker ensures identical trip behavior and electrical characteristics to your original equipment.

With a 3-Pole configuration, it disconnects all three phases synchronously, reducing the risk of phase-to-phase faults and ensuring safer shutdowns for motors, drives, and other three-phase loads. The 600V rating makes it suitable for standard industrial distribution systems, giving you a trusted line of defense against overloads and short circuits.

Ideal use cases

  • Maintenance and downtime planning: stock this exact KL3300L to minimize panel downtime when breakers trip or fail.
  • Retrofit projects: upgrade legacy panels with a breaker that matches the original specs exactly.
  • Replacement in 3-phase, 600V systems: keeps electrical protection consistent across upgrades.

Compatibility and ordering tips

Important: confirm fit and ratings before ordering. The KL3300L part number is your best reference for compatibility. Check that your panel is rated for 600V and that the bus configuration and mounting style align with the KL3300L design. When in doubt, consult your equipment datasheet or reach out to the supplier with the exact part number to verify fit.

Practical considerations

  • Ensure proper safety procedures during installation and testing.
  • Store spares in a clean, dry environment to preserve performance.
  • Keep a spare KL3300L on hand for critical processes to reduce downtime.
