The OFPF Series 2P (Double-Pole) miniature circuit breaker is a high-performance, full-pole protection device specifically designed for single-phase AC distribution systems. Its core function is to ensure the true synchronized interruption of both the line (L) and neutral (N) conductors through a built-in, integrated mechanical linkage mechanism. This product not only provides precise overload and short-circuit protection for wiring and equipment but also achieves complete electrical isolation of the circuit. It fundamentally eliminates the potential safety risks associated with a neutral conductor that may remain live when only the line conductor is disconnected. It is the ideal core protection component for various single-phase power distribution scenarios that have explicit or mandatory requirements for operational safety, maintenance safety, and fault isolation integrity.
