The Allen-Bradley 140G-K-FMX04 Flex Cable Operator is a painted metal flex cable assembly for the Bulletin 140G Molded Case Circuit Breaker product line that is designed to provide simplified installation and control procedures for flange-mounted circuit breaker systems. This cable assembly is ideal for flange-enclosed molded case circuit breakers (MCCBs), and it is suitable for applications with limited panel space. It is also suitable in tight-space applications where there is a need to control the circuit breaker from a remote location. Unlike conventional control methods that use operating rods or special mounting plates for control, the 140G-K-FMX04 flex cable assembly provides control through a cable, thus offering flexibility within the circuit breaker system. The 140G-K-FMX04 flex cable assembly is used only with 3-pole Molded Case Circuit Breakers (MCCBs), and it can also be used in Bus bar mounting system applications and installed within a control panel.

The 140G-K-FMX04 flex cable assembly has a maximum cable length of 1.3 meters (4.0 feet) and it is compatible with the 3-pole Allen-Bradley K-Frame molded case circuit breakers. It has a painted metal handle with the NEMA Type 1 and 12 enclosure ratings, and its enclosure is designed to provide a degree of protection to the users in an indoor industrial environment. The 140G-K-FMX04 flex cable operator assembly comes pre-assembled with a handle, an MCCB operator, a cable, a mounting plate, and the necessary hardware for easy and simplified field installation. The compatible replacement parts for this cable operator assembly includes a non-metallic flange handle with mounting hardware, a stainless steel-handle with mounting hardware, flange handle hardware that is K-Frame compatible, and actuator mounting hardware, all of which can be ordered separately. The 140G-K-FMX04 flex cable assembly is CE, UL, and CSA certified.
