I found this excellent Magnetic circuit breaker. Short of an electronic one like the PCX-AC, this is the best breaker you'll find.
Here's the spec sheet for the AirPAX Snapak Series breakers. Here's a good price for them if you don't mind waiting a few weeks: Airpax PP11-0-10.0A-OB-V $11.00 for quantity one.
