Key Features

• Model Compatibility: Specifically designed as an alternative to Mitsubishi NF series, featuring perfect interchangeability with the original model, directly replaceable without modifying the installation structure, saving time and cost for equipment maintenance and replacement.
• Thermal-Magnetic Tripping: Adopts advanced thermal-magnetic tripping technology, which can accurately detect overload and short circuit faults. The thermal release responds to overload current slowly to avoid false tripping, while the magnetic release acts quickly when short circuit occurs, effectively cutting off the circuit in time to protect electrical equipment and personnel safety.
• Excellent Breaking Capacity: With a breaking capacity of 35kA at 380/440V, it can reliably interrupt large fault currents, ensuring the stability of the entire power distribution system and preventing the spread of electrical faults.
• Standard Configuration: 3-pole (3P) design, rated current of 600A, rated voltage of AC 380V/440V, fully meeting the power supply needs of medium and large power equipment and power distribution cabinets.
• Durable Construction: Made of high-quality flame-retardant and insulation materials, the molded case is impact-resistant, high-temperature resistant and corrosion-resistant, ensuring a long mechanical and electrical service life, even in harsh industrial environments.
• Easy Installation & Maintenance: Compact and reasonable structural design, adopting standard mounting size, convenient for wiring and installation; the shell is easy to disassemble, facilitating daily inspection and maintenance, reducing maintenance workload.
• Standard Compliance: Strictly complies with international standards IEC 60947-2 and national standard GB 14048.2, passing strict quality inspection, with reliable quality and safe use.
• Cost-Effective: As a domestically produced high-quality alternative, it has the same performance as the original Mitsubishi NF series, but with a more competitive price, helping customers reduce procurement costs while ensuring product quality.
