LAB23000MW | Circuit Breaker | 400A | 2-Pole | 600V

Meet the LAB23000MW industrial circuit breaker — a robust, maintenance-ready solution engineered for reliability in demanding electrical environments. Designed for retrofit, replacement, and ongoing service needs, this 400A, 2-pole unit delivers dependable overcurrent protection for up to 600V circuits, helping keep critical equipment running smoothly.

Key specifications at a glance

• Amperage: 400 A
• Poles: 2-Pole
• Voltage rating: 600 V
• Reference: Part number LAB23000MW
• Compatibility reminder: Confirm fit and ratings before ordering; the LAB23000MW part number is the best reference for compatibility.

Why this breaker stands out

What makes the LAB23000MW unique isn’t just its technical specs — it’s how those specs translate into real-world reliability. This 2-pole design isolates two conductors with a single action, delivering clean shutdown of both lines in the event of an overcurrent. The 400A rating supports heavy-duty circuits found in industrial equipment, manufacturing lines, and control panels, while the 600V capability aligns with common industrial distribution standards. When you’re performing maintenance, retrofits, or replacements, having a matching part number (LAB23000MW) on hand minimizes guesswork and downtime.

Ideal use cases and applications

• Maintenance and service of industrial control panels requiring a 400A, 2-pole breaker
• Retrofit projects where existing equipment calls for a 600V, two-hot-line protection device
• Spare parts inventory for long-term equipment reliability and quick field replacements
• Replacement of worn or obsolete breakers in heavy-load electrical enclosures

Practical considerations for installation

Before ordering, verify that the LAB23000MW aligns with your panel’s design and ratings. Rely on the part number LAB23000MW as the primary reference to ensure compatibility with your existing gear. If you’re updating an installation or sizing for a new project, cross-check connection type, mounting footprint, and trip characteristics with your panel documentation to avoid mismatches that could lead to downtime.

Usage tips and insights

• Keep a lab-tested spare LAB23000MW on site for planned maintenance and unexpected outages.
• Label the part clearly in your spare parts kit with the exact part number to streamline future replacements.
• Pair with proper protective accessories and enclosure guidelines to maintain intended protection levels and safety standards.

Designed for serious industrial environments, the LAB23000MW 400A 2-Pole 600V circuit breaker offers a clear pathway to safer, more reliable electrical distribution. Its specificity—down to the part number—helps you make confident sourcing decisions, minimizes downtime, and aligns with standard maintenance workflows for industrial equipment and control systems.
