Drop-In Compatible, Cost-Effective Alternative for NF Series 250amp Molded Case Breakers
1. Key Replacement Advantages
Direct drop-in replacement for NF250-CW models. Same dimensions, wiring interface, and mounting specifications—no modifications needed for installation.
Rated at 250A with 3-pole configuration, matching the original’s thermal-magnetic trip characteristics, breaking capacity, and voltage ratings. Provides the same level of overload and short-circuit protection.
Competitive pricing without compromising quality. Ideal for bulk replacement projects, equipment retrofits, and inventory restocking to reduce operational costs.
Manufactured to meet IEC60947-2 standards, with CE/CCC certifications. Every unit undergoes 100% factory testing to ensure consistent performance.
