Eaton 58811-400 Circuit Breaker

The Eaton 58811-400 circuit breaker is a protective electrical device from Eaton, identified by part number 58811-400. It is designed to interrupt current in a circuit when overcurrent or short‑circuit conditions occur, helping prevent damage to conductors, devices, and insulation. Typically installed in electrical panels, it provides overcurrent protection by opening the circuit when the load exceeds its rated level and restores service once the fault is cleared. As part of Eaton's circuit-breaker family, the 58811-400 is built to meet the brand's reliability and field replacement standards and is intended for use with compatible Eaton panelboards and accessories. This type of device plays a critical role in electrical safety, enabling quick isolation of a fault to minimize heat buildup, arcing, and potential equipment damage. For proper installation and operation, follow relevant electrical codes and the panel's listing and labeling, and ensure the unit is used only in configurations specified by Eaton's official documentation for the 58811-400 model.
