Description
Engineered for commercial and industrial applications, the Siemens HED41B110 provides reliable thermal-magnetic protection within the Sentron family. This 110-amp, single-pole breaker mounts into P1, P2, and P3 panelboards as well as SB switchboards. Featuring a high interrupting capacity of 100kA at 120VAC, it handles demanding fault conditions. While this specific ED-frame model is highly sought after, it is eventually replaced by the 3VA5111-6ED16-0AA0 with an adapter kit.Specifications
