Built for commercial and industrial applications, the Siemens CE3B015 is a 3-pole, 15A legacy molded case circuit breaker. It provides reliable thermal-magnetic protection for critical downstream equipment. This bolt-on breaker installs into Siemens and ITE P2 or P3 panelboards. As a discontinued unit, it serves as an exact fit replacement, superseded by the CED63B015. Rated 100kAIC at 480VAC, this current-limiting device uses integrally fused limiters to safely interrupt massive faults.
