Product Description
The w58xc4c12a-20 is a TE Connectivity Potter & Brumfield W58 thermal push-to-reset circuit breaker rated 20 amperes at 50 VDC or 250 VAC. This breaker protects avionics and electrical branch circuits on aircraft panels by interrupting current flow when overcurrent conditions occur. The thermal mechanism responds to sustained overload while the push-to-reset design allows manual circuit restoration after a trip event.
Installation follows aircraft maintenance manual specifications and FAA AC 43.13-1B circuit protection guidance for proper sizing and panel mounting.
