The 140U-H0C3-C40 circuit breaker is an Allen-Bradley circuit breaker. The current rating of the H-Frame 140U-H0C3-C40 circuit breaker is 40 Amps. At 480 Volts AC voltage, the rated interrupting rating or breaking capacity is more than 100 kiloamps. The trip unit on the 140U-H0C3-C40 circuit breaker is fixed thermal and fixed magnetic and it is a three-pole breaker. The 140U-H0C3-C40 circuit breaker is a Bulletin 140U series circuit breaker. Circuit breakers from this series are rated for 15 to 1200 Amps of current and they come with either electronic or thermal-magnetic trip mechanisms. Frame H breakers have a maximum current rating of 125 Amps and they conform to the following standards: the CCC, KEMA, IEC 60947-2, CE, and UL 489 standards. The 140U-H0C3-C40 circuit breaker comes with a thermal-magnetic trip unit.

The main function of the 140U-H0C3-C40 circuit breaker is to protect electrical circuits against ground faults, short circuits, and overloads. The circuit breaker can be used as either the main circuit protection device or as a branch circuit protection device in enclosures, panelboards, and switchboards. The power dissipation for the 40 Amps rated 140U-H0C3-C40 circuit breaker is 15 Watts. At 60 Hertz, the interrupting rated specifications are 200 kiloamps at 240 Volts AC, 100 kiloamps at 480 Volts AC, and 35 kiloamps at 600 Volts AC. For optimal operation, the 140U-H0C3-C40 circuit breaker should be operated in an environment where the ambient temperature remains between 16 and 140 degrees Fahrenheit. The mechanical specifications for the breaker include a weight of 3 pounds and dimensions of 139.7 x 50.8 x 76.2 millimeters. Compatible shunt trips are available from Allen-Bradley for applications that require the remote tripping of the 140U-H0C3-C40 circuit breaker.
