Schneider Electric ECB24020G3 Circuit Breaker

Schneider Electric’s Square D ECB24020G3 PowerLink G3 two-pole molded‑case circuit breaker is a 20 A device designed for 480Y/277 VAC systems, delivering 14 kA short‑circuit current rating at 480 V, with bolt‑on mounting and remote operation. The unit belongs to the ECB‑G3 family and uses a permanent thermal‑magnetic trip unit in each pole to provide both long‑time overload protection and instantaneous short‑circuit protection, and it is TAA‑compliant for compatibility with government and other regulated installations. The design supports straightforward integration within Schneider Electric control ecosystems and is commonly employed to protect feeders and branch circuits in commercial and industrial distributions; while this specific model targets 480 VAC applications, the ECB‑G3 line includes two‑pole breakers tailored to a range of voltages and ratings, up to higher interrupting capacities at lower voltages depending on the exact variant.
