Siemens AG ED41B015 Molded Case Circuit Breaker

Siemens ED41B015 Sentron Type ED4 molded‑case circuit breaker delivers compact, reliable overcurrent protection for 1‑pole circuits in commercial panels. It is a 15 A device designed for 120/277 V AC operation, with a 22 kA interrupt rating at 277 VAC, suitable for branch‑circuit protection in lighting, receptacle runs, and similar loads. This ED4 frame unit uses thermal‑magnetic trip technology to provide both overload and short‑circuit protection and features the robust molded‑case construction for durable field wiring and panel replacement. As part of Siemens' Sentron ED4 family, the ED41B015 shares common mounting and electrical characteristics with other ED4 devices, enabling straightforward integration in Siemens‑based distribution schemes. Typical applications include commercial lighting panels, building distribution boards, and small power circuits where precise 15 A protection and a high interrupt rating are required to minimize fault damage and downtime.
