M9F42330 Miniature Circuit Breaker, Multi9 C60BP, 3P, 30A
The M9F42330 Miniature Circuit Breaker (MCB) is a low-voltage protection device from the Schneider Electric Multi9 C60BP series. This 3-pole circuit breaker with 3 protected poles is designed for distribution applications, offering robust protection for both electrical equipment and personnel by mitigating electrical threats such as short circuits and overloads. It also helps optimize energy consumption and improve life-cycle asset management in various electrical systems.
This MCB has a rated current of 30 Amperes and features a C tripping curve (thermal-magnetic technology), making it suitable for general-purpose protection in circuits with moderate inrush currents. It is compatible with AC network types.
The CCS-M9F42330 boasts impressive breaking capacities:
- UL 489 / CSA C22.2 No 5:
- 10 kA AIR at 480Y/277 V AC
- 14 kA AIR at 240 V AC
- EN/IEC 60947-2 / GB 14048.2 (Icu):
- 6 kA at 440 V AC
- 10 kA at 415 V AC
- 20 kA at 240 V AC
Its rated service breaking capacities (Ics) are robust, typically 75% of Icu, ensuring reliable reclosing after fault clearance.
Designed for straightforward installation, this MCB can be clipped onto a DIN rail and occupies a width of 6 pitches (54mm). It offers an electrical endurance of 10,000 cycles and a mechanical endurance of 20,000 cycles, ensuring long-term reliability. The operational voltage is 240VAC, 415VAC, or 440VAC. It has a rated insulation voltage of 500VAC and an impulse withstand voltage of 6kV.
The breaker maintains an IP20 degree of protection on its terminals (IP40 when installed in a modular enclosure) and can operate reliably in ambient temperatures ranging from -30°C to 70°C (-22°F to 158°F). Its gray color and compact dimensions (54mm W x 103mm H x 72mm D) make it suitable for various panel designs. This product complies with both industrial standard EN/IEC 60898-1 and residential standard EN/IEC 60947-2, and is certified by IEC, CCC, CSA, and UL, making it an excellent choice for original equipment manufacturers (OEMs) and control panel builders. It features tunnel type terminals suitable for rigid wires from 1 to 35 mm² and flexible wires from 1 to 25 mm².
