As part of the 140MP MPCB family, it can also function as a manual motor starter when paired with compatible Allen‑Bradley 100‑C or 100‑K contactors to form a two‑component motor starter, a common setup in industrial motor control. The unit delivers a 3 kA short‑circuit rating and is rated for up to 690 V AC operation, making it suitable for typical 480–690 V motor circuits, with UL\/CSA listing for the 140MP protection lineup. This model is designed for straightforward integration with Rockwell Automation literature such as 140MP‑TD002\/TD005 for precise electrical ratings and mounting guidelines, helping ensure correct fit with accessories and enclosures. \u003c\/p\u003e\u003c\/div\u003e","brand":"circuit","offers":[{"title":"New","offer_id":51678090821934,"sku":null,"price":131.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_700ff1d0-b60c-4b34-a920-70b29ee13267.jpg?v=1769571605","url":"https:\/\/plgautomation.com\/products\/circuit-140mp-a3e-b40-motor-protection-circuit-breaker","provider":"PLG Automation ","version":"1.0","type":"link"}
