This component enables the safe mechanical interlocking of two contactors, ensuring that only one contactor can be engaged at a time, which is a crucial safety requirement in reversing motor starter assemblies and similar control schemes. The 100-MCA00 provides a direct, mechanical linkage without reliance on electrical interlocks or auxiliary contacts, reducing failure points and simplifying maintenance. Compact and easy to install, it is a commonly selected interlock for most sizes within the 100-C series, with the exception of models 100-C40 and 100-C90. Allen Bradley’s quality standards ensure durability, reliability, and compliance with global certifications such as UL, CSA, and CCC, making it an established choice for industrial automation panels where safety and performance are paramount.\n\n\u003ch2\u003eKey Features of Allen Bradley 100-MCA00\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned for mechanical interlocking of two Allen Bradley 100-C contactors\u003c\/li\u003e\n  \u003cli\u003eNo auxiliary contacts – purely mechanical operation\u003c\/li\u003e\n  \u003cli\u003eQuick installation between adjacent contactors\u003c\/li\u003e\n  \u003cli\u003eCompatible with most 100-C models (excludes 100-C40 and 100-C90)\u003c\/li\u003e\n  \u003cli\u003ePromotes safe control by preventing simultaneous engagement of both contactors\u003c\/li\u003e\n  \u003cli\u003eDurable construction meets industrial safety standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specs of 100-MCA00\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eType: Mechanical interlock device\u003c\/li\u003e\n  \u003cli\u003eFor use with: Allen Bradley 100-C contactors (except 100-C40, 100-C90)\u003c\/li\u003e\n  \u003cli\u003eOperation: Mechanical only, no auxiliary contacts\u003c\/li\u003e\n  \u003cli\u003eIncluded: 100 S9 Connector\u003c\/li\u003e\n  \u003cli\u003eCertifications: UL, CSA, CCC, KC compliance\u003c\/li\u003e\n  \u003cli\u003eMounting: Between adjacent 100-C series contactors\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eApplications \/ Use Case\u003c\/h2\u003e\nThe Allen Bradley 100-MCA00 is essential in electrical control panels where safety interlocking of two contactors is mandatory, such as reversing starters for three-phase motors or changeover systems. By mechanically linking two contactors, this interlock physically prevents both from being closed at the same time, eliminating the risk of short circuits or dangerous electrical cross-connection. Its application is common in manufacturing lines, conveyor systems, and motor control centers where dependable, hardware-level safety is required. The 100-MCA00’s compatibility across most of the 100-C contactor series makes it a versatile accessory for OEM panel builders and facility maintenance personnel managing multi-motor controls, safety circuits, or redundant switching schemes.\n\n\u003ch2\u003eRelated Resources\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/\" target=\"_blank\"\u003eLeadTime.ca – Industrial Automation Components \u0026amp; Repair Services\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/collections\/allen-bradley\" target=\"_blank\"\u003eView All Allen Bradley Products\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/blogs\/learning-center\/examples-of-industrial-automation-control-systems\" target=\"_blank\"\u003eExamples of Industrial Automation and Control Systems\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/products\/allen-bradley-194e-sy\" target=\"_blank\"\u003eAllen Bradley 194E-SY Disconnect Switch\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/products\/allen-bradley-1609-d600n\" target=\"_blank\"\u003eAllen Bradley 1609-D600N UPS Backup Power Supply\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Allen Bradley","offers":[{"title":"Default Title","offer_id":47870749868331,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/4671\/7995\/files\/Leadtime_711afc09-f6b5-4963-bce2-523c02368e72.png?v=1723533034","url":"https:\/\/leadtime.ca\/products\/allen-bradley-100mca00","provider":"LEADTIME","version":"1.0","type":"link"}
