The 140M-L8P-D40 circuit breaker is a motor protection circuit breaker. It is part of the Allen-Bradley Bulletin 140M product line which includes 0.16 to 1200 Amps rated circuit breakers. The bulletin 140M motor protection circuit breakers provide short circuit protection, but overload protection needs to be provided separately. A visible trip indication is available on the 140M-L8P-D40 circuit breaker. Agency approvals for the Bulletin 140M devices include the CE and CSA approval ratings. Furthermore, the Bulletin 140M devices conform to multiple industrial standards including the IEC, CSA, and UL 489 / UL 508 standards. The circuit breaker comes in an L-frame enclosure. The maximum current rating for the L-frame breakers is 600 Amps. Accessories available for the 140M-L8P-D40 circuit breaker from Allen-Bradley include trip indication contacts, auxiliary contacts, and flexible cable operators.
The 140M-L8P-D40 circuit breaker is engineered to provide manual switching, to disconnect motor circuits, and to provide branch circuit and short circuit protection. The rated operational current for the 140M-L8P-D40 circuit breaker is 400 Amps. The tripping module on the circuit breaker is a magnetic trip unit. The Horsepower output power ratings which the 140M-L8P-D40 circuit breaker can support are 100, 200, 250, and 300 Horsepower at 200, 230, 460, and 575 Volts AC, respectively, and the kilowatt output ratings are 90, 160, 200, and 250 kilowatts at 230, 400/415, 500, and 690 Volts AC, respectively. The magnetic trip setting on the circuit breaker can be set at 2000, 2250, 2500, 2750, 3000 3250, 3500, 3750, and 4000 Amps. Only trained and experienced technicians should be involved in the designing and installation of systems which include the 140M-L8P-D40 circuit breaker. The power should be disconnected prior to the installation and servicing processes. Failure to do so could lead to equipment damage, injury, and even death.
