About the GD3050

The GD3050 is an Eaton Cutler-Hammer molded case circuit breaker that is engineered under the C Series of circuit breakers. The circuit breaker features 3 poles and it produces a maximum current of 50 Amps. The GD3050 also features a maximum voltage of 480 Volts AC and 250 Volts DC. The GD3050 produces a kAIC of 22 at 480 Volts AC, one of 65 kAIC at 240 Volts AC, and one of 10 kAIC at 250 Volts DC. The module has a shipping dimension of 4 inches in height, 3.8 inches in width, and 6.7 inches in length. The shipping weight for the module is 2 pounds. The Eaton Cutler-Hammer line of C Series molded case circuit breakers are designed to offer circuit protection for low-voltage distribution systems. The GD3050 is described by NEMA as a unit that offers a closing and interrupting circuit between the separable contacts under usual and unusual circumstances.

The GD3050 has been designed so that it can open and close circuits manually and it also opens the circuit automatically on a predetermined current overload. With these features, the GD3050 has the ability to protect the conductors and the connected applications that include the motors and motor starters, and it also offers protection against short circuits. The GD3050 has been designed for electrical and industrial applications serving a range of equipment with proven designs that incorporate the latest technological innovations. If offers a high level of availability and reliability to the users. The GD3050 includes 3 pole breakers that are used for many 3-phase loads with a grounded phase that comes connected via a breaker pole. The 3-pole breakers also come in handy for the single-phase loads that can be connected through the outside poles. The GD3050 is also suitable for the 240 Volts AC corner grounded delta systems. With the GD3050, the protected phase-to-protected phase interruption values will not be affected by corner grounded configurations.
