Description
Supplying reliable long-time and instantaneous trip functions, this 20-amp molded case breaker supports 240V, 480V, and 250VDC commercial applications. The bolt-on design ensures a stable connection within Siemens Sentron panelboards and legacy ITE F-Series infrastructure. Facility managers often utilize this exact E4 series hardware to maintain older systems, though it has been officially superseded by the ED43B020. It carries an HACR rating and supports reverse feed installations.
