140M-I8E-D16

The 140M-I8E-D16 circuit breaker is a circuit breaker that has been designed and manufactured by Allen-Bradley/Rockwell Automation. This breaker has been designed exclusively to operate with industrial motors. It provides branch-circuit and short-circuit protection and it can be used while attached to a motor or while installed with a series of breakers to protect a system of multiple pieces of equipment. The Allen-Bradley/Rockwell Automation 140M-I8E-D16 circuit breaker provides a high interrupting capacity and its main detection mechanism consists of both an adjustable thermal mechanism and a fixed magnetic mechanism. These 2 detection mechanisms help the breaker be more effective when it is detecting current and protecting motors from excessive currents. When employing thermal detection, it is important to avoid extremely high temperatures in the surrounding environment since these temperatures can affect the thermal detection mechanism. In environments that contain a significant amount of particles, it is recommended to install the breaker in a proper enclosure that offers enough protection to the circuit breaker.

The Allen-Bradley/Rockwell Automation 140M-I8E-D16 circuit breaker operates with a rated current of 205 Amps and a current range of 40 to 205 Amps. It has a trip class rating of 5 to 20 Amps and it complies with the CSA 22, UL 508, UL 489, IEC, and CE standards. The Allen-Bradley/Rockwell Automation 140M-I8E-D16 circuit breaker ships with an external rotary operator, a flex cable operator, auxiliary contacts, and trip indication contacts. The breaker must be installed and connected by using copper and aluminum wirings that are rated for 75 degrees Celsius during operation to ensure these wires can resist the same maximum temperatures that the breaker can.
