Eaton Cutler-Hammer's LD3450, part of the Series C Circuit Breakers, is engineered to handle substantial electrical loads. This molded case circuit breaker is configured with three poles, establishing it as suitable for three-phase power applications. It has a maximum rated current capacity of 450 A, designed to operate effectively at a voltage rating of 600 VAC for alternating current and 250 VDC for direct current.
The breaker possesses impressive interrupting ratings, capable of withstanding fault currents of up to 65 kAIC at 240 VAC, 35 kAIC at 480 VAC, 25 kAIC at 600 VAC, and 22 kAIC for DC applications. This level of interrupting capability makes it appropriate for situations where sudden surges in current are expected. For trip functionalities, the LD3450 utilizes fixed thermal and magnetic mechanisms with long-time and instantaneous (LI) trip settings, allowing for reliable operational protection against overcurrents. The Universal Product Code (UPC) for this unit is 786679015612.
