M9F42105 Miniature Circuit Breaker, Multi9 C60BP, 1P, 5A
The M9F42105 Miniature Circuit Breaker (MCB), identified by Manufacturer Part Number (MPN) M9F42105, is a low-voltage protection device from the Schneider Electric Multi9 C60BP series. This 1-pole circuit breaker with 1 protected pole is designed for a variety of electrical applications, providing enhanced protection for both personnel and equipment by mitigating electrical threats such as short circuits and overloads. It also helps optimize energy consumption and improve life-cycle asset management.
This MCB has a current rating of 5 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 both AC and DC network types.
The CCS-M9F42105 boasts significant breaking capacities:
- UL 489 / CSA C22.2 No 5:
- 10 kA AIR at 277 V AC
- 14 kA AIR at 240 V AC
- 14 kA AIR at 120 V AC
- 10 kA AIR at 60 V DC
EN/IEC 60947-2 / GB 14048.2 (Icu):
- 3 kA at 415 V AC
- 10 kA at 240 V AC
- 20 kA at 60 V DC
Its rated service breaking capacities (Ics) are robust, typically 75% of Icu for AC and 75% for DC, ensuring reliable reclosing after fault clearance.
Designed for ease of installation, this MCB can be clipped onto a DIN rail and has a narrow width of 2 pitches (18mm). It offers an electrical endurance of 10,000 cycles and a mechanical endurance of 20,000 cycles. The operational voltage is 240VAC or 415VAC (AC) and 60VDC (DC), with 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 in a modular enclosure) and can operate reliably in ambient temperatures ranging from -30°C to 70°C (-22°F to 158°F). Its light grey color and compact dimensions (18mm W x 103mm H x 72mm D) make it suitable for various panel designs. This product complies with various international standards, including UL 489, CSA C22.2 No 5, EN/IEC 60947-2, and GB 14048.2, and is certified by IEC, CCC, CSA, and UL. It features tunnel type terminals suitable for rigid wires from 1 to 25 mm² and flexible wires from 1 to 16 mm².
