Excellent product. I hate using the slip on connections for my circuit breakers and these units offered the screw in security. Awesome

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.

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.
