The Eaton Cutler-Hammer 140G-K15F3-D40 circuit breaker is a molded case circuit breaker that is part of the 140G series. It features the K frame type with a current range of 400 Amps. This circuit breaker features an interrupt rating of 150 kA with 3 poles. It also features the adjustable thermal or adjustable magnetic type of protection. The Eaton 140G-K15F3-D40 circuit breaker and the whole 140G series of molded case circuit breaker series provides a variety of specifications. In addition to the electronic protection and thermal or magnetic protection features, it also offers accessories for high braking or interruption capacities which are both field and factory-installed. The 140G series circuit breakers are best used for control panel line protection.

Other features of the 140G-K15F3-D40 circuit breaker and other molded case circuit breakers come with a current rating ranging from 10 to 3000 Amps, and dimensions that save space. These circuit breakers have standard end cap or bolt-on terminals, and the 140G series circuit breakers are approved by and accepted for universal applications by the CSA, UL, CCC, and the IEC standards. They offer exceptional performance and circuit breaking capacities. These molded case circuit breakers also feature a wide range of options for mounting as well as a range of field or factory-installed accessories. Generally, the molded case circuit breakers are engineered to protect and shield conductors and other equipment against overcurrent by opening spontaneously in advance before the current upsurges to a value or duration that may lead to extreme and dangerous temperatures in the conductors. Also, the 140G-K15F3-D40 circuit breaker can be used as the primary means of disconnection for a control panel. The protection that this circuit breaker offers relates to short-circuit currents and overcurrent protection.
