TE P&B CIRCUIT BREAKER W58-XC4C12A-5
The W58 series breaker is exactly the same type I had in my C172 - which really came in handy since it mated successfully to my avionics buss bar.
Fast shipping, what I needed. Great product!
Replaced a seventy year old hydraulic motor breaker on my Swift. The old one was working fine until I rebuilt the motor and replaced the brushes. Apparently the degradation of the motor had masked the degradation of the original breaker, to be discovered on my biannual. The new 30 Amp breaker seems to have the system working great again.
Worked as expected.
great product and price.
fast service and just what I needed. will use again
