Repost to provide the correct picture of the metal bar. Please note that I
have exhausted the largest local electric supply house, Home Depot, eBay,
ETA (internet search of catalog), etc.

I bought a very old house and have difficulty finding a replacement circuit
breaker. The control panel is labeled as Cutler Hammer. The closest
circuit breaker I can find locally is CH130 (1 pole, 30A), shown at the top
of
http://home.comcast.net/~cfjwang/CH-Breakers.jpg . The bottom part is the
one I am trying to replace. It has a notch on one side. There is metal bar
inside the control panel that prevents the CH130 from being plugged in,
while the notch on the old circuit breaker allows for the insertion. (The
metal bar is shown in the lower middle part of
http://home.comcast.net/~cfjwang/Bar.jpg).

Can anyone help me identify what type of circuit breaker this is and where I
can buy these?

Best regards,

Jerry
