Power Distribution - Low current breakers or fuses?

[diviney]

Hello:

The 2009 Power Distribution module utilizes the regular "Maxi" breakers in the 40 A slots. This is fine for high-current users like drive motors, etc. We would wire these with the usual AWG 10 and all is well.

I am baffled by the 30 amp slots however. It was disappointing to find that these slots do NOT accept the standard ATC / ATO fuses. Instead, the documentation refers to VB3 breakers. These slots should be useful for lower current distribution such as the 12V supply to the Digital Sidecars, Analog Breakouts, etc. For these functions, it is desirable to use smaller wire gauges (let's say maybe AWG 20 or similar). This would demand fusing these circuits for ~ 5A in order to safely protect the wiring. We were not given any breakers less than 20A with the controller kit. What's worse, I can't seem to locate any useful references to "VB3" breakers or fuses to purchase them.

Does anyone know if / where we can obtain breakers / fuses compatible with the 30A slots in the 2009 PD module (in particular, low current values)? I can't see running 14 gauge wire around to all the low-power circuits just because we can't get a breaker less than 20A for the PD module...
