The 140U-JD0D3-D17 circuit breaker is a 175 Amps rated compact molded case circuit breaker which forms part of the Bulletin 140U circuit breaker series designed and produced by Allen-Bradley. Applications for the 140U-JD0D3-D17 circuit breaker include branch circuit and main circuit protection in bus-bar trunking tap-offs and switchboards. The purpose of the 140U-JD0D3-D17 circuit breaker is to provide protection against ground faults, overloads, and short-circuits. The 3-pole 140U-JD0D3-D17 circuit breaker comes in a JD-frame enclosure and it has a voltage rating of 480 Volts AC. The trip unit on the 140U-JD0D3-D17 circuit breaker is an adjustable magnetic-fixed thermal unit and the breaker has a breaking capacity rating in excess of 100 kiloamps at 480 Volts AC. The standards with which the 140U series complies with include the CE, CCC, KEMC-KEUR, and UL 489 standards.

Circuit breakers require regular maintenance to ensure electrical safety, comply with safety regulations, and avoid costly facility downtime. Typically, the circuit breaker maintenance needs to be performed at regular intervals. However, periodic maintenance does not account for environmental conditions or usage patterns. Using IoT and analytic based technologies have recently been proposed to enable a predictive approach to circuit breaker maintenance. These novel approaches can increase safety levels, increase device operational lifespan, and optimize operational costs. The planning and installation of systems that incorporate the 140U-JD0D3-D17 circuit breaker must be performed by trained and experienced technicians. This must be done to ensure that all the relevant safety precautions are followed so that equipment damage and serious injury to the working staff are avoided. Failure to do so can lead to equipment damage, injury, and even death.
