This high-performance LS ABN/ABS/ABE 3P MCCB Replacement is a direct drop-in replacement for LS Electric (formerly LG) Metasol ABN/ABS/ABE series 3-pole molded case circuit breakers, designed for reliable protection in industrial power distribution and motor control systems. Available in 400AF frame size with rated current options of 250A, 300A, 350A, and 400A, this 250-400A motor protection switch serves as a core safety component for your electrical infrastructure.

✅ Key Features

1. Dual Protection Mechanism: Equipped with proven thermal-magnetic trip technology, providing time-delay overload protection and instantaneous short-circuit protection to safeguard cables, motors, and electrical equipment from burnout and fault expansion.
2. Wide Compatibility: 3P design fits 3-phase 3-wire systems, with a maximum rated operating voltage of AC 690V. Ideal for use as main incoming switches in distribution systems, non-frequent start switches for motor circuits, and general power protection in factories, commercial buildings, and infrastructure projects.
3. Multiple Series Options for All Needs:
   Series	Positioning	Core Features	Application Scenarios
   ABE Replacement	Economy	Standard breaking capacity, cost-effective	General lighting, conventional distribution circuits
   ABS Replacement	Standard	Balanced breaking capacity, universal	Industrial main circuits, standard motor protection
   ABN Replacement	High Performance	High breaking capacity, superior reliability	Critical industrial systems, high-current main switches

4. Full Specification Coverage: 400AF frame size supports 250A/300A/350A/400A current ratings, compatible with original model numbers including ABN403c, ABS403c, ABE403b. Optional accessories (shunt trip, auxiliary contacts, etc.) are available for customization.
5. Reliable Quality: Manufactured to meet international electrical standards, with CCC, CE certification compliance. Compact structure, long service life, and stable operation ensure long-term reliability in harsh industrial environments.
