Schneider Electric C120H125 Molded Case Circuit Breaker

Schneider Electric Acti9 C120H125 2-pole molded case circuit breaker (model A9N18459) provides reliable protection for branch circuits in low-voltage distribution panels. Rated for 125 A and featuring a C-type trip curve, it offers a 15 kA breaking capacity in accordance with IEC 60898-1 and IEC 60947-2. The two-pole configuration ensures simultaneous disconnection of both conductors, enhancing safety for multi-wire circuits. As part of the Acti9 C120H family, this unit shares the same form factor and terminal interfaces as other C120H devices, simplifying stocking and replacements within a Schneider Electric system. Typical applications include protecting feeders and branch circuits in residential, commercial, and light-industrial installations where a 125 A, 2-pole, C-curve breaker is appropriate. This model is designed for use in standard low-voltage distribution boards and is built to meet the referenced IEC standards for predictable, proven performance.
