🔹 Product Overview
This ABS54c is a high-performance molded case circuit breaker (MCCB) that is a direct replacement for the LS Electric (formerly LG) Metasol series. Designed for low-voltage distribution systems, the 4-pole (4P) structure is compatible with 3-phase 4-wire circuits, with 15A/50A rated current options and a 25kA rated ultimate short-circuit breaking capacity. It can be used as the main incoming switch for distribution boxes and cabinets, perfectly replacing the original imported model with full performance compliance and excellent cost-effectiveness.
