About the HMDL3300

The Eaton Cutler-Hammer HMDL3300 is a thermal-magnetic circuit breaker with non-interchangeable trip units that belongs to the C Series of molded circuit breakers, specifically to the M frame product line of circuit breakers. The Eaton Cutler-Hammer HMDL3300 thermal-magnetic circuit breaker with non-interchangeable trip units is intended for general purposes applications. This kind of breaker is also considered to be a standard breaker in the industry. The mechanism of the Eaton Cutler-Hammer HMDL3300 thermal-magnetic circuit breaker with non-interchangeable trip units is based on the use of 2 metals that react to the temperature generated by the current and an electromagnet located in place. Meaning that it has a double mechanism for protection.

The Eaton Cutler-Hammer HMDL3300 thermal-magnetic circuit breaker with non-interchangeable trip units has a frequency rating of 50 to 60 Hertz and an amperage rating of 300 Amps. This breaker has a high interrupting capacity, which makes it ideal for this kind of application. The maximum rating is tested in the open air when it is used within an enclosure or at higher temperatures than normal, where it might be possible to derate the breaker. This occurs due to the slow heat dissipation that enclosures provide. As an alternative, small enclosures with proper ventilation mechanisms can also be used. The Eaton Cutler-Hammer HMDL3300 thermal-magnetic circuit breaker with non-interchangeable trip units includes the complete breaker, and it has a weight of 20 pounds, a length of 18 inches, a width of 11 inches, and a height of 8 inches. Internal accessories can be added to boost the performance of the breaker. The most common are alarms, auxiliary switches, and low energy shunt trips.
