The OFNC series two-pole (2P) miniature circuit breaker is a high-performance full-pole protection device designed for single-phase distribution systems. The key advantage of this product lies in 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 potential safety risk that may arise from disconnecting only the phase line while the neutral line remains possibly live. For any single-phase distribution application where operational safety and fault isolation integrity are explicitly required or mandatory, this product is a core protection component.
