About the HMDL3400

The HMDL3400 is a high-capacity circuit breaker that has been manufactured by Eaton Cutler-Hammer. This breaker offers protection to electrical circuits against the excess current that an overload or short circuit produces. The Eaton Cutler-Hammer HMDL3400 high-capacity circuit breaker combines the thermal and magnetic mechanisms to detect these kinds of faults and to interrupt the current before it can cause any damage to the whole circuit or the equipment attached to it. The Eaton Cutler-Hammer HMDL3400 high-capacity circuit breaker belongs to the C Series of molded case breakers and it has been designed according to the standards of M frame specifications. It features 3 poles that are connected by the means of a bar.

The Eaton Cutler-Hammer HMDL3400 high-capacity circuit breaker has an amperage rating of 400 Amps and it operates with a frequency of 50 and 60 Hertz. This amperage rating has been calculated at a specific temperature of 40 degrees Celsius and it has been tested previously in the open air. Once a fault has occurred and it has been corrected and cleared, the breaker can be put back into service immediately. The size of the Eaton Cutler-Hammer HMDL3400 high-capacity circuit breaker is the standard size that corresponds to the M frame, with a height of 8 inches, a length of 18 inches, and a width of 11 inches with an approximate weight of 20 pounds. These dimensions are the size of the complete breaker. The interrupting capacity of the Eaton Cutler-Hammer HMDL3400 high-capacity circuit breaker varies depending on the voltage applied, for example, at 240 Volts AC, it has a performance of 100 symmetrical Amps.
