The ABB SH203-NA ARVP is a specialized, 3-pole miniature circuit breaker (MCB) with a specific auxiliary function and high interrupting capacity, as indicated by the combined suffixes "-NA" and "ARVP". This MCB is designed for three-phase circuit protection in commercial and industrial applications where both enhanced short-circuit breaking performance and a remote tripping/status signaling capability are required. The "ARVP" suffix typically denotes that the breaker is factory-equipped with a specific auxiliary switch or alarm contact module. It provides standard overload and short-circuit protection while offering a remote electrical signal for control or monitoring purposes.
