140M-L2E-D40

The Allen-Bradley 140M-L2E-D40 circuit breaker is a motor protection circuit breaker rated for 400 Amps of operational current. The motor current adjustment range is from 160 to 400 Amps. The tripping mechanism on the breaker is a standard magnetic trip. The 140M-L2E-D40 circuit breaker is a standard performance circuit breaker that is available in an L-frame enclosure. The ultimate interrupting current at 400 Volts AC voltage is 40 kiloamps and the ultimate interrupting rating at 480 Volts AC voltage is 35 kiloamps. The magnetic trip current rating is 4800 Amps. At 200 Volts AC, the 3-phase output power rating is 125 Horsepower, at 230 Volts AC the 3-phase output power rating is 150 Horsepower, at 460 Volts AC, the 3-phase output power rating is 300 Horsepower, and at 575 Volts AC, the 3-phase output power rating is 400 Horsepower. The 3-phase power ratings in kilowatts at 230, 400/415, 500, and 600 Volts AC are 132, 200, 250, and 400 kilowatts, respectively.

The 140M-L2E-D40 circuit breaker is part of the Bulletin 140M motor protection circuit breakers product line from Allen-Bradley. This product line offers breakers in a 0.1 to 630 Amps operational current range. The 140M series devices are UL-listed for motor loads and they feature visible trip indication, high current limiting, and a high switching capacity. The 140M circuit protectors provide overload protection and short circuit protection for individual motor loads. The factory-fitted internal accessories facilitate the wiring and installation processes. Agency approvals for the 140M devices like the 140M-L2E-D40 circuit breaker include the UL, CSA, and CE standards. Other standards include the UL 508, UL 489, CSA C22 No 14, and 60204-1 standards. The available accessories include flexible cable operators, trip indication contacts, an external rotary operator, and auxiliary contacts.
