140M-D-PNC23 | Allen-Bradley Connecting Module for 140M-D to 100-C09...C23

This connecting module is ideal for motor control systems in industrial automation, such as conveyors, pumps, and fans. It’s commonly installed in MCCs (motor control centers) and panelboards where modular and space-saving designs are critical. Its primary use is to integrate protection (via the circuit breaker) with control (via the contactor). This integration is vital in systems that require coordinated motor starting, overload protection, and disconnection. The module helps reduce wiring time and improves the reliability of electrical connections.

The precise dimensions of the 140M-D-PNC23 are not typically listed independently, as it is a connecting accessory rather than a standalone module. However, it is designed to match the height and depth of the 140M-D circuit breakers and 100-C contactors. This ensures flush mounting and a neat, compact motor starter assembly. The combined unit, once assembled, maintains standard enclosure and panel clearances. For exact sizing in control panel layouts, it's recommended to refer to Rockwell’s dimensional diagrams of the assembled units.

The 140M-D-PNC23 is mounted by snapping it directly between the circuit breaker and the contactor without any external wiring. It uses pre-defined slots and connectors to ensure a secure and accurate fit. The module requires no additional tools, which speeds up the installation process. Once connected, it ensures correct alignment for power and signal transfer. This approach not only saves time but also enhances system reliability by reducing potential wiring errors.

The module supports motor applications in the 25–45 Amp range, matching the contactors and circuit breakers it connects. It operates with systems that use standard industrial voltages and frequencies. While the module itself doesn’t handle the full load current directly, it is designed to ensure proper contact and secure electrical performance between the two components. This makes it suitable for use in moderate to heavy-duty motor loads. Its robust design guarantees stable operation even under frequent switching conditions.

Yes, the 140M-D-PNC23 is currently an active product in Allen-Bradley’s portfolio. It is available through Rockwell Automation and authorized distributors. However, like many specialized components, availability may vary depending on region and distributor stock. Users planning to purchase this part for new installations or spare parts should confirm availability ahead of time. Rockwell also offers support for compatible replacements if needed in the future.
