At 480Y\/277 VAC it carries a 14,000 AIR (14 kA) interrupt rating, while at 240 VAC the rating rises to 42,000 AIR (42 kA), making it suitable for feeder protection in industrial distribution panels and 3‑phase equipment circuits. This device is part of Schneider Electric’s Powerlink G3 lineup, engineered with a factory preset thermal and magnetic trip in each pole to ensure reliable protection without external accessories. The ECB34020G3 is a 3‑pole, 20 A MCB designed for use in high‑voltage, three‑phase systems, and its performance characteristics align with typical Powerlink G3 specifications for 480Y\/277 VAC installations, where protection against overload and short circuits is essential for safe, continuous operation.\u003c\/div\u003e","brand":"Square","offers":[{"title":"New","offer_id":46258989170922,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-012.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/schneider-electric-ecb34020g3-miniature-circuit-breaker","provider":"GTG Hardware","version":"1.0","type":"link"}
