140A-C-ASA11

Overview of Allen Bradley 140A-C-ASA11

The Allen Bradley 140A-C-ASA11 is a side-mounted auxiliary contact designed for use with 140A series manual motor starters. This 2-pole contact block features a 1 NO/NC (normally open/normally closed) configuration and adds 9 mm to the width of the manual motor starter when installed on the left side. Manufactured by Rockwell Automation, this auxiliary contact is built to provide reliable signaling and control feedback in motor protection applications. The unit operates with a contact rating of 2 A at 230 VAC-15, making it suitable for low-power control circuits that require status indication or interlocking functions. The 140A-C-ASA11 integrates directly with 140A manual motor starters rated from 0.1 to 16 amperes, supporting motor protection across a wide range of industrial applications. When using this side-mounted auxiliary contact, compact bus bars with 54 mm spacing must be employed to accommodate the increased width. The contact block maintains IP20 protection when properly wired and operates reliably in ambient temperatures ranging from -25°C to +60°C, matching the environmental specifications of the 140A starter series.

Applications / Use Case

The Allen Bradley 140A-C-ASA11 auxiliary contact serves critical roles in motor control panels where status monitoring and interlocking are required. In manufacturing facilities, this contact block provides real-time feedback on motor starter state to programmable logic controllers (PLCs) or supervisory control and data acquisition (SCADA) systems. The 1 NO/NC configuration allows engineers to implement both normally open alarm circuits and normally closed safety interlocks within the same device. Common applications include conveyor systems, pump stations, HVAC equipment, and machine tools where motor starter status must be communicated to central control systems. The contact block is particularly useful in control panels requiring compact layouts, as the 9 mm width addition keeps footprint minimal. When paired with 140A manual motor starters rated from 0.1 to 16 amperes, the 140A-C-ASA11 enables complete motor protection schemes with integrated status feedback. Industrial applications benefit from the wide operating temperature range and IP20 protection, ensuring reliable performance in typical panel enclosure environments. The side-mount design simplifies retrofitting existing installations without requiring complete starter replacement.
