140U-H6C3-D11

The 140U-H6C3-D11 Molded Case Circuit Breaker by Allen-Bradley/ Rockwell Automation has a supply voltage rating of 480 Volts at 60 Hertz frequency, a rated current of 110 Amps, an interrupt rating of 25 kA, a 3-pole configuration, and it is factory assembled and ready to install when it ships. It offers trip types that are a fixed thermal trip type and a fixed magnetic trip type with a trip rating of 110 Amps for the thermal trip type and it is 1100 Amps for the magnetic trip type. The Allen-Bradley 140U-H6C3-D11 Circuit Breaker has passed international standard ratings such as the CSA 22.2 (No. 5), IEC 60947-2, and the UL 489 standards. In addition, it also has international approvals from the CE, UL List, KEMA-KEUR, and the CSA Certification standards.

The Allen-Bradley 140U-H6C3-D11 Circuit Breaker has accessories which include internal control modules such as the auxiliary contact (AX) that shows the breaker's status as either on or off,  the alarm contact (AL) shows the state of the breakers when it is tripped, the auxiliary alarm contact (AX/AL) that is both the auxiliary contact and alarm contact combined, the shunt trip (SNT) that offers the circuit breaker a remote tripping option but not undervoltage tripping, and the undervoltage release (UVT) that trips the breaker automatically if the voltage drops to between 35 and 70% of the present value. The shunt trip is usually not used when the undervoltage release trips the breaker. Other Allen-Bradley 140U-H6C3-D11 Circuit Breaker accessories include external accessories such as the mounting hardware, the terminal end cover, the motor operator, the terminal shields, the flex-cable operating mechanism, and the rotary with a variable-depth and direct couple operating mechanism. The Allen-Bradley 140U-H6C3-D11 Molded Case Circuit Breaker has a maximum ambient temperature of 40 degrees Celsius (104 degrees Fahrenheit) without derating, and a storage temperature range of -40 to 80 degrees Celsius (-40 to 176 degrees Fahrenheit).
