Schneider Electric EHB24020HIDU Circuit Breaker

Schneider Electric's Square D EHB24020HIDU is a two‑pole molded‑case circuit breaker rated for 20 A in 480Y/277 V systems, designed for bolt‑on mounting in commercial and industrial panels. As part of the EHB family, this thermal‑magnetic device provides overcurrent protection for three‑phase, four‑wire circuits and HID lighting feeders, with a typical interrupting rating of 14 kAIC at 277 V on many EHB models. The unit is intended for use in panels that support EHB‑style breakers and is compatible with 480Y/277 V operation, reflecting common high‑voltage distribution and HID lighting installations. Schneider Electric notes that the EH/EHB series are obsolete without replacement, so available inventory and support may vary; for new designs, consider newer Square D products that meet current code and compatibility requirements. This exact model, EHB24020HIDU, is listed as a 20 A, 2‑pole device suitable for 480Y/277 V service in appropriate panel configurations.
