The ABB SH201-NA 2P 80A is a specialized, 2-pole, 80A miniature circuit breaker (MCB) with a specific interrupting characteristic or high breaking capacity, likely denoted by the "-NA" suffix. This MCB is designed for applications requiring a robust protective device capable of handling higher prospective fault currents or specific installation requirements. It provides reliable overload and short-circuit protection for single-phase circuits (Phase + Neutral) or two-phase circuits with high current demands, commonly found in main distribution panels, large appliance feeds, or commercial/industrial sub-circuits.
