140G-HTF3-C80

The 140G-HTF3-C80 circuit breaker is a molded case circuit breaker. Eaton Cutler-Hammer manufactures the circuit breaker. The 140G-HTF3-C80 circuit breaker is classified under the Eaton 140G series of circuit breakers. The Eaton Cutler-Hammer molded case circuit breakers are used for opening and closing a circuit through non-automatic means. However, the unit also delivers automatic circuit opening when there is a predetermined overcurrent. The operation takes place while ensuring the protection of the unit, and ensuring that it is correctly applied according to the ratings of the circuit breaker. The 140G-HTF3-C80 circuit breaker features the adjustable thermal or the adjustable magnetic protection methods. It comes with a current range of 80 Amps, and the rated impulse withstand voltage is 8 kV.

The 140G-HTF3-C80 circuit breaker features a trip unit. The current rating is 125 Amps and the unit features the HC frame type. The 140G-HTF3-C80 circuit breaker comes with a mechanical lifespan of 240 operations per hour. The 140G-HTF3-C80 circuit breaker is considered to be a molded case circuit breaker. “Molded case” refers to the construction of the 140G-HTF3-C80 circuit breaker. Ideally, the molded case circuit breakers are assembled units that are built in a supporting housing that is made of insulating material. The 140G-HTF3-C80 circuit breaker provides protection to the applications by opening before the predetermined maximum current level is reached. Protection is provided through the use of mechanical means and heater elements. Alternatively, the users can detect the electronics current flow, modeling the associated heat that is generated by the unit’s current.
