NJL-S2400 | Circuit Breaker | 400A | 2-Pole | 240V

The NJL-S2400 Circuit Breaker is a purpose-built solution for industrial electrical distribution, delivering reliable protection for 240V circuits when 400A capacity is required. This 2-pole unit is designed for maintenance, retrofit, and replacement projects where exact specifications matter and panel compatibility is critical.

• Amperage: 400A
• Poles: 2-Pole
• Voltage: 240V
• Compatibility reference: Part number NJL-S2400 is the best reference for ensuring a proper fit

Why choose the NJL-S2400 in your installation

• Drops into compatible industrial panels that require a 400A, 2-pole, 240V protection device without extensive modification
• Clear, unambiguous compatibility through the exact part number, reducing guesswork during maintenance or retrofit
• Solid performance under typical factory loads, protecting feeders and critical circuits from overloads and faults

Ideal use cases

• Maintenance and service upgrades in manufacturing lines, data centers, or distribution rooms where 400A protection is needed
• Retrofits that must preserve existing form-factor and electrical characteristics
• Replacement for aging or failed breakers within 240V, 2-pole distribution circuits

Practical guidance for ordering and installation

• Before ordering, confirm fit and ratings against your panel’s data sheet. The NJL-S2400 part number is your quickest reference for compatibility
• Verify 240V system configuration and ensure the panel accepts a 2-pole device of 400A continuous rating
• During installation, follow standard electrical torque specifications and safety protocols for high-current breakers
