The OFL7 series two-pole (2P) miniature circuit breaker is a full-pole protection device specifically designed for single-phase AC distribution systems. The core feature of this product is its built-in integrated mechanical linkage mechanism, which ensures true synchronous opening of the phase line (L) and the neutral line (N). This circuit breaker not only provides precise overload and short-circuit protection for lines and equipment, but also achieves complete electrical isolation of the circuit, thereby fundamentally eliminating the safety risk that may arise from disconnecting only the phase line while the neutral line remains potentially live. For any single-phase distribution application where operational safety and fault isolation integrity are explicitly required or mandatory, this product is an ideal core protection component.
