Industrial WKDN400 400A 3-Pole 600 V Circuit Breaker

The WKDN400 Industrial Circuit Breaker—Part Number WKDN400—delivers dependable overcurrent protection for demanding three-phase power systems. Rated for 400 A and designed for 600 V operation, this 3-pole unit is tailor-made for robust industrial distribution where reliability matters most.

• 400 A current rating handles large feeders and motor circuits, reducing nuisance trips on startup and heavy loads.
• 3-pole design provides synchronized protection across all three phases, preserving balance in three-phase networks.
• 600 V voltage rating suits common industrial power distributions, from manufacturing lines to facility-wide panels.
• Integrated, space-conscious form consolidates protection for three phases into a single device, helping simplify wiring and panel layout.

Who should consider the WKDN400? It’s ideal for factories, workshops, and facilities with mid-to-large scale electrical feeders, motor drives, conveyors, compressors, and other heavy equipment that require reliable interruption in fault conditions.

• Motor control centers (MCCs), switchboards, and distribution panels where three-phase protection is essential.
• Industrial automation setups with large loads that benefit from predictable trip characteristics and quick isolation of faulted circuits.
• New installations where a compact, dedicated 3-pole breaker reduces panel footprint and simplifies wiring.

What makes this circuit breaker stand out

• Specific design for industrial environments where uptime matters—built to handle continuous operation in demanding settings.
• Clear part identification (WKDN400) simplifies inventory, maintenance, and cross-reference with electrical schematics and spare parts catalogs.
• Versatile for both new builds and upgrade projects, offering reliable protection without incompatible adapters or add-ons.

Practical tips for installation and use

• Verify your system is a three-phase network and that the 600 V rating matches your distribution voltage before installation.
• Ensure proper mounting in an appropriate enclosure and follow all local electrical codes for wiring, torque specs, and safety clearances.
• Plan for coordination with upstream protective devices to achieve selective tripping and minimize system-wide outages.

In short, the Industrial WKDN400 400A 3-Pole 600 V Circuit Breaker is a precise, reliable choice for safeguarding essential industrial circuits. With its 400 A capacity, three-phase protection, and 600 V rating, it’s built to keep your motors, conveyors, and power distribution running smoothly while providing clear, actionable protection when faults occur.
