These bi-metallic single pole breakers weigh less than 2 oz. and are especially suitable for homebuilt aircraft. Used as original equipment in Beech, Cessna and Piper aircraft. Maximum operating voltages: 32 VDC and 250 VAC (to 400 Hz).
Push/Pull Actuator Thermal Circuit Breaker
Cannot be reset against overload
W23 has visible trip indicator
Appears good, just like the W31, except that Load and Line are reversed (to dimensionally align mounting holes and buss attachment, requires that these be mounted upside down (so 10 amp reads 0l instead of 10).
Unlike the original circuit breaker, this one has terminals labeled LOAD and LINE. On a 1964 Bonanza the LINE side is on the bottom, which means that the silk screened AMP number will be upside down when the circuit breaker is installed. The manufacturer should have provided a reversible AMP number disc, or a sticky label to correct for this issue.
Exactly what I ordered
I was disappointed that the breaker I received was not like the one pictured but had the flip switch rather than than the push button like the rest of my panel.
Service was fantastic, ordered it Tuesday from Australia and it arrived Friday from you. Many thanks!!
Looked for a match in style ,physical shape ,and colour for my panel Quick service was good.
It was what I needed for a new alternator installation, or at least close enough. The drawing I had called for 55 amp, but all I was able to find was 50 amp. Close enough.
My aircrafts got Tyco breakers from the start and I dont believe in mixing, so I continue using Tyco breakers, even if the thing is really brittle and you should be very careful when tightening or loosening the terminators or youll find yourself with a broken breaker. Use pliers to hold the metal connector.
An industry standard that can always be trusted for construction and accuracy at a reasonable price
W23 series circuit breakers have 8-32 threaded screws on the terminals.
These breakers do not have FAA PMA approval on their own. Many certified aircraft have these breakers as OEM and thus are approved under the airframe approval as replacement parts. Please discuss with your A&P to see if these can be installed legally in your aircraft.
