Siemens HNG3F120 is a molded case circuit breaker frame designed for providing robust overcurrent protection in three-phase industrial power distribution systems. It is rated for 600V AC applications with a continuous current rating of 1200A and features a thermal-magnetic protection mechanism for long-time and instantaneous (LI) trip functions, ensuring reliable circuit interruption. The unit is constructed as a three-pole, bolt-on NG frame with a 65kA interrupting capacity at 480V, built to withstand demanding electrical environments. It complies with relevant industry standards for safety and performance in electrical protection. This frame is typically applied in main distribution panels, switchgear, and other high-capacity industrial installations where a dedicated trip unit is specified separately.
