About the LDB3350

The LDB3350 is a 3-pole Series C Type LDB Cutler-Hammer thermal-magnetic circuit breaker manufactured by Eaton Cutler-Hammer. It has an L Frame and it is rated at 600 Volts AC or 250 Volts DC maximum operating voltage, and at 350 amps continuous current. The range of its interrupting capacities are 65, 25, 35, and 22 kAIC at 240 Volts AC, 600 Volts AC, 480 Volts AC, and 250 Volts DC, respectively. The LDB3350 thermal-magnetic circuit breaker is suitable for providing high-performance overload protection, main and branch circuit protection, as well as switching control for industrial equipment and circuits such as induction motors and motor control centers. It features non-interchangeable fixed thermal and thermal-magnetic trip units on each pole and it comes equipped with standard line and load terminals that support the use of different cable types that match its rating.

A molded case enclosure houses all the internal components of the LDB3350 thermal-magnetic circuit breaker. This enclosure is built from the best glass-polyester material to repel moisture and inhibit the growth of fungus while providing appropriate insulation to ensure user safety. The toggle switch operating mechanism of the LDB3350 circuit breaker provides ease-of-operation and it also indicates if the beaker is on, off, or tripped. This breaker features a push-to-trip button for manually testing its functionality and it can only be manually turned back on after a trip out. It features an optional shunt trip, under-voltage release, and alarm switch. For flexibility of use and application, the LDB3350 thermal-magnetic circuit breaker is compatible with many Series C circuit breaker accessories.
