Product Description
The w58xc4c12a3 is a TE Connectivity Potter & Brumfield W58-series thermal circuit breaker rated for 50 VDC maximum operation. This push-to-reset breaker protects aircraft electrical circuits from overcurrent conditions, automatically interrupting power when current exceeds the rated amperage. Panel-mounted in avionics feeder circuits and general electrical distribution systems, it provides reliable protection without requiring fuse replacement.
Installation requires matching the breaker amperage to wire gauge per aircraft wiring diagrams and securing screw terminals to the panel. Common in general aviation and business aircraft electrical systems where automatic reset protection is preferred over single-use fuses.
