About the LD3350

The Eaton Cutler-Hammer LD3350 Molded Case Circuit Breaker is an L Frame circuit breaker in the Series C family of molded case circuit breaker with a thermal-magnetic non-interchangeable trip used for circuit protection in a variety of low voltage applications. This device, like all Series C circuit breakers, is designed to provide fast-acting and effective protection from overload and short circuits, and it is designed with both line and load side terminals, which allows for easy and convenient field wiring. The LD3350 is designed for use with applications with a maximum operating voltage of 600 Volts AC, and it has a carrying current (nominal current) of 350 Amps. It has an interrupting capacity of 35 kAIC at 400 Volts, and it can be used to protect appliances like motors and motor starters from circuit overloads.

This circuit breaker is a complete assembled device comprising a frame, terminals, and a fast-acting trip unit. Its trip unit is designed to be field adjustable to meet operation demands, and its magnetic trip element can be adjusted to up to 10 times its nominal current rating. Its copper/aluminum load and line terminals provide easy means of wiring, and they are CSA rated to meet the continuous current ratings. The LD3350 has a 40 degrees Celsius operating temperature limit, and at any temperature above that, the device will start to de-rate. It is suitable for non-corrosive and non-condensing relative humidity conditions. The LD3350 weighs around 9.1 kilograms (20 pounds), with total mounting dimensions of 209.6 x 273.1 x 103.1 millimeters (8.25 x 10.75 x 4.06 inches), and it is UL, CSA, CE, and BS certified.
