Schneider Electric M9F43204 Two Pole Circuit Breaker

Schneider Electric M9F43204 is a two-pole Miniature Circuit Breaker from the Multi9 C60BP family, designed to provide overcurrent protection for branch circuits in electrical distribution and control panels. It is rated for 240/415 VAC, 50/60 Hz, with a nominal current rating of 4 A and a D-curve trip characteristic to accommodate moderate inrush loads typical of lighting and small-motor circuits. The unit offers a high breaking capacity of up to 20 kA at 240 VAC and 10 kA at 415 VAC, meeting UL 489 and IEC/EN 60947-2 standards for interrupting fault currents. Its two-pole construction ensures simultaneous disconnection of both conductors, enhancing safety on split-phase and three-phase systems and simplifying wiring in enclosures. As part of Schneider Electric’s Multi9 line, M9F43204 is cataloged as a 2P 4A D-curve MCB within the C60BP sub-range; verify the exact voltage, current, and breaking-capacity ratings in your local Schneider Electric listing for your installation. Typical applications include branch-circuit protection for lighting, receptacle circuits, and small-power loads in commercial or light-industrial environments, as well as protection of control circuits in machines and equipment where a dedicated two-pole disconnect is required.
