NFM – Molded Case Circuit Breakers (MCCBs) for Industrial Protection
NFM, or Molded Case Circuit Breakers (MCCBs), are essential protective devices in low-voltage electrical distribution systems. These robust units are designed to handle high current ratings, typically from 16A up to 1600A, with breaking capacities ranging from 25kA to 150kA at 415V AC. They feature adjustable thermal-magnetic or electronic trip units for precise overload and short-circuit protection. Available in 3-pole (3P) and 4-pole (4P) configurations, NFM breakers support fixed, plug-in, or draw-out mounting styles. They operate at rated voltages up to 690V AC and 500V DC, with frequency ratings of 50/60 Hz. Key accessories include auxiliary contacts, shunt trips, undervoltage releases, and motor operators. The compact design and high interrupting capacity make them ideal for main switchboards, distribution panels, and motor control centers.
These circuit breakers are widely deployed in industrial plants, commercial buildings, data centers, and renewable energy installations. They are commonly found in main distribution boards (MDBs), sub-distribution boards (SDBs), and as incoming protection for variable frequency drives (VFDs) and soft starters. NFM units are also used in generator sets, UPS systems, and power factor correction banks. Their ability to withstand harsh environments with IP20 to IP54 protection ratings ensures reliable operation in factories, warehouses, and outdoor substations. In automation systems, they protect critical loads like PLCs, sensors, and actuators from electrical faults.
The NFM category includes several subcategories such as fixed type MCCBs (e.g., NFM-F series), plug-in type (NFM-P series), and draw-out type (NFM-D series). Key article codes follow a structured pattern: NFM-100S (100A frame, standard breaking), NFM-250H (250A frame, high breaking), and NFM-630L (630A frame, limited breaking). Other notable codes include NFM-400E (400A electronic trip) and NFM-800R (800A with remote operation). Each code typically includes frame size, breaking capacity (S, H, L, R), and pole configuration (e.g., NFM-250H-3P). These breakers are available with various trip units: thermal-magnetic (TM), electronic (LSI), and selective (LSIG).
