The 140G-H2C3-C63 circuit breaker is an H-Frame, 3-pole molded case circuit breaker manufactured by Allen-Bradley. It is a member of the Allen-Bradley 140G series and it is rated 690 Volts AC operating voltage, 63 Amps of current, 36 kA of interrupting capacity at 440 Volts AC, 10 kA of interrupting capacity at 690 Volts AC. Its protection type is a fixed thermal and fixed magnetic trip unit with a 63-Amp thermal trip current rating and 630-Amp magnetic trip current rating. The 140G-H2C3-C63 circuit breaker is designed to effectively protect equipment and conductors from short-circuit, overload, or overcurrent situations.

The Allen-Bradley 140G-H2C3-C63 circuit breaker features high-repulsion contacts that use reverse loop technology to ensure fast responses to fault conditions during operation. It features a switch handle for operation and it is equipped with a DIP switch for protective features that allow maintenance work to be done while the circuit breaker is energized. This circuit breaker has a glass fiber housing that is reinforced with synthetic resins to allow for its use in varied industrial environments. It supports reverse feed use and it can serve as a feeder circuit or branch circuit protector. The Allen-Bradley 140G-H2C3-C63 molded case circuit breaker relies on its arc chamber to swiftly extinguish the arcing that occurs whenever the contacts are opened. This unit can be mounted on a control panel or within an enclosure. It is designed for worldwide use and its metallic components are corrosion-resistant. The 140G-H2C3-C63 circuit breaker supports vertical and horizontal mounting. To comply with the NEC standards, the “ON” position of the switch must be oriented upwards when this unit is mounted vertically.
