140U-I3C3-D12-S

The 140U-I3C3-D12-S circuit breaker is an I-Frame thermal-magnetic circuit breaker with a non-adjustable magnetic trip. This breaker has been manufactured and designed by Allen-Bradley and included in the 2100 combination series. This breaker has a continuous current rating of 125 Amps and a Horsepower rating of 20 to 50 Horsepower. It also comes with a magnetic trip range of 800 to 1600 Amps. The Allen-Bradley 140U-I3C3-D12-S I-Frame thermal-magnetic circuit breaker has a medium interrupting capacity and it includes a current limiter. This extra feature is in charge of establishing a limit to the current that is going to be delivered to a load. The Allen-Bradley 140U-I3C3-D12-S I-Frame thermal-magnetic circuit breaker comes with a NEMA 3 enclosure. This enclosure rating is equivalent to the IP 54 designation, which means that it protects the circuit breaker against solid particles as well as liquids. It is important to note that the breaker must not be exposed to corrosive materials and chemicals that can damage its structure.

The 140U-I3C3-D12-S circuit breaker can be installed in any position and the installation location must be analyzed to determine whether it has the proper conduits and surfaces that are needed to install the breaker. The 140U-I3C3-D12-S circuit breaker is an I-Frame thermal-magnetic circuit breaker with a non-adjustable magnetic trip that has two different detection mechanisms that work with magnets and temperature. Both of these mechanisms can detect a different kind of current. Once the breaker trips, it indicates a high fault current and it can be set back into operation once this fault has been cleared and corrected. Unlike fuses, this breaker can be used multiple times after detecting faults.
