This unit, part of Challenger's CSK molded‑case family, is intended for three‑phase 240 V circuits and is compatible with Challenger panelboards and enclosures that support CSK‑series MCCBs. The 3‑pole construction ensures simultaneous disconnection of all phases during an overcurrent event, helping protect downstream wiring and equipment in commercial and light industrial installations. As a molded‑case breaker, the CSK3150 U offers a compact form factor suitable for crowded electrical layouts, combining straightforward mounting with solid insulation. It protects feeders and branch circuits supplying loads such as motors, transformers, and other 3‑phase equipment on a 240 V system, enabling reliable isolation of faults and safer maintenance in appropriate installations. Use of this 150 A, 240 V device fits main feeder protection or branch protection roles within distribution panels and switchgear where three‑phase 240 V service is employed. \u003c\/p\u003e\u003c\/div\u003e","brand":"CHALLENGER","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51677932749102,"sku":null,"price":169.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_ef42f7ef-958c-4b18-b7cd-4fc305d6515f.jpg?v=1769569659","url":"https:\/\/plgautomation.com\/products\/challenger-csk3150-u-molded-case-circuit-breaker","provider":"PLG Automation ","version":"1.0","type":"link"}
