Siemens E23B070 U Contactor

Siemens ED23B070 (often cataloged as E23B070) is a three‑pole molded‑case circuit breaker (MCCB) rated for 70 A at 240 V AC, designed to protect 3‑phase feeders in commercial and industrial power distribution. It delivers a 10 kA interrupting capacity at 240 V, providing robust short‑circuit protection for typical feeders while helping prevent nuisance trips in normal operation. This ED2‑series device integrates thermal‑magnetic trip protection and supports standard line and load terminations for straightforward installation in Siemens panels, switchgear, and motor‑control centers. The model is commonly used for 3‑phase circuits up to 70 A in distribution and control applications and is widely stocked by distributors to support replacement and retrofit inexisting installations that specify the ED/E2 family. regional labeling may vary between E23B070 and ED23B070, but the electrical ratings are consistent across listings.
