Rockwell Automation: New Motor Protection Circuit Breakers Offer Space, Time and Cost Savings

January 29, 2020

Engineers can use the new Allen-Bradley 140MP Motor Protection Circuit Breakers from Rockwell Automation to simplify motor protection.

The circuit breakers, also known as motor-protective switching devices, can be mounted on Allen-Bradley 100-C or 100-K contactors to create a two-component motor starter. The devices provide magnetic short-circuit protection and thermal-overload protection up to 32 A, and interrupting ratings up to 100 kA at 400 V.

The circuit breakers are enabled by UL approval for use in group installation. This type of installation can reduce panel space, installation and wiring time, and overall costs by eliminating the need for individual branch short-circuit protective devices for each motor circuit.
