It features a compact design with a 4 pole, 4 normally open (NO) contact arrangement, supporting efficient signal switching and control. With a 440V AC coil (50 Hz) and 480V AC rating at 60 Hz, this relay is suitable for standard control systems requiring reliable operation at higher voltages. The device handles up to 10 amps and supports screw terminal connections, making it practical for straightforward wiring and fast installation on standard 35mm DIN rails. The 700-K40E-B stands out for its longevity—offering up to 300,000 operations—and optional top-mounted auxiliary contact blocks allow for flexibility in contact arrangement. Its robust performance and modularity make it a cost-effective solution for diverse switching applications in demanding environments.\n\n\u003ch2\u003eKey Features of Allen Bradley 700-K40E-B\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e4 pole, 4 NO (normally open) contacts for versatile control\u003c\/li\u003e\n  \u003cli\u003eRated for 440V AC (50 Hz) and 480V AC (60 Hz) coil voltage\u003c\/li\u003e\n  \u003cli\u003e10A contact rating with silver bifurcated contacts for long life\u003c\/li\u003e\n  \u003cli\u003eScrew terminal connections for secure wiring\u003c\/li\u003e\n  \u003cli\u003eDIN rail mountable for quick panel integration\u003c\/li\u003e\n  \u003cli\u003eExpandable configuration with up to four additional auxiliary contacts\u003c\/li\u003e\n  \u003cli\u003eCompact dimensions: approx. 45mm W x 49mm D x 56mm H\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specs of 700-K40E-B\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eBrand: Allen Bradley\u003c\/li\u003e\n  \u003cli\u003eModel: 700-K40E-B\u003c\/li\u003e\n  \u003cli\u003eContact Configuration: 4 NO (normally open) poles\u003c\/li\u003e\n  \u003cli\u003eCoil Voltage: 440V AC 50 Hz \/ 480V AC 60 Hz\u003c\/li\u003e\n  \u003cli\u003eContact Rating: 10A\u003c\/li\u003e\n  \u003cli\u003eTerminals: Screw\u003c\/li\u003e\n  \u003cli\u003eMounting: 35mm DIN rail\u003c\/li\u003e\n  \u003cli\u003eDimensions: 45mm(W) x 49mm(D) x 56mm(H)\u003c\/li\u003e\n  \u003cli\u003eConductor Size: 18–12 AWG\u003c\/li\u003e\n  \u003cli\u003eWeight: 163 g\u003c\/li\u003e\n  \u003cli\u003eCountry of Origin: Switzerland\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eApplications \/ Use Case\u003c\/h2\u003e\nThe Allen Bradley 700-K40E-B is well-suited for industrial automation, machine building, and process control environments. It is commonly chosen for control panels where compact relays are needed to handle power switching, signaling, and logic interlocks. Facilities benefit from its reliable operation in applications requiring frequent cycling—such as motor starters, power distribution panels, and safety circuits. Thanks to its DIN rail mountable design and additional pole options, the 700-K40E-B streamlines panel layouts and facilitates fast field replacement. This model’s high voltage coil compatibility and extended mechanical lifespan help reduce maintenance, minimize downtime, and support seamless integration in both new and retrofit installations within manufacturing plants, utilities, and OEM equipment.\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-1321-3r18-b\" target=\"_blank\"\u003eAllen Bradley 1321-3R18-B Resistor Assembly\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Allen Bradley","offers":[{"title":"Default Title","offer_id":47870782767403,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/4671\/7995\/files\/Leadtime_80538770-fdf8-4e92-b426-36239000a5db.png?v=1723532195","url":"https:\/\/leadtime.ca\/products\/allen-bradley-700-k40e-b","provider":"LEADTIME","version":"1.0","type":"link"}
