Schneider Electric ECB32030G3U Circuit Breaker

Schneider Electric’s Square D PowerLink ECB32030G3U is a three‑pole molded‑case circuit breaker in the ECB‑G3 family, rated for 30 A and 240 V AC for three‑phase protection. It uses a thermal‑magnetic trip mechanism to guard against overloads and short circuits and offers a 42 kA short‑circuit rating at 240 V, making it suitable for distribution panels in light industrial and commercial electrical systems. The ECB32030G3U is designed specifically for 240 V operation and is part of Schneider Electric’s PowerLink ECB‑G3 line, which includes 1P/2P/3P variants (ECB14030G3, ECB24030G3, ECB32030G3) to cover common 120/208/240 V three‑phase feeder configurations. Typical applications include feeding subpanels or motor‑control circuits in commercial or light‑industrial installations, where a 30 A, 240 V three‑phase protective device helps coordinate upstream protection with downstream loads.
