The EHD3040 is a circuit breaker with a current of 40 Amps from Eaton/Westinghouse. The breaker has 3 poles and it can be used with a 3-phase power supply. The maximum voltage rating for the EHD3040 is 480 Volts AC. The EHD3040 also supports a DC voltage to a maximum of 250 Volts DC. The circuit breaker belongs to Series C of Cutler-Hammer circuit breakers. The EHD3040 uses a complete molded case and it uses an F-frame type in the EHD family. The EHD3040 has terminals on the load side and it operates within a frequency range of 50 and 60 Hertz. The interrupt rate for the EHD3040 is 14000 AIC at 480 Volts AC, 10000 AIC at 250 Volts DC, and 18000 AIC at 240 Volts AC. the height, width, and depth measurements for the EHD3040 are 4.9 inches x 4.9 inches x 7.7 inches, respectively. The EHD3040 weighs 4 pounds.
The trip mechanism used by the EHD3040 circuit breaker is a fixed magnetic fixed thermal type. With this type of tripping mechanism, once the circuit trips, the tripping mechanism must be allowed to cool down to the recommended temperature before a reset can be successfully initiated. The EHD3040 Westinghouse molded case circuit breaker has a maximum operating temperature rating of 40 degrees Celsius and it uses a bolt-on connection. Series C molded case Eaton circuit breakers, including the EHD3040, can be used in distribution systems to provide branch and main circuit protection. Additionally, these Series C circuit breakers can be mounted in individual enclosures where specific requirements need to be met.
