Siemens EE3B010 U Electromechanical Relay Assembly

Siemens EE3B010 U is a three-pole molded-case circuit breaker (MCCB) rated for 10 A at 240 VAC, designed to protect three‑phase feeders in distribution panels. It delivers up to 10 kA of interrupting capacity at 240 VAC, enabling safe disconnection of faults in commercial and light-industrial electrical systems. The EE3B010 U is part of Siemens' EE3B family (the legacy ITE line), offering dependable overload and short-circuit protection in compatible Siemens panelboards and MCCB enclosures. With three poles, this device supports three‑phase power, making it suitable for protecting motors, pumps, fans, and other three‑phase loads in feeders and branch circuits. The model is commonly used as a replacement in EE3B-compatible installations, where a 10‑A, 240‑V MCCB with a 10 kAIC rating is required. When selecting a replacement, verify panel compatibility and mounting footprint with the EE3B series to ensure proper fit and electrical clearance.
