Review: Decent Mini Breakers for Home Projects - I used these in a little control panel that I built to supply power to a couple of power vents on my roof. They work fine for my purposes. A lot of people commented that they are not stable on the DIN Rail; however, these are meant to be used with DIN Rail End Anchors to keep them securely in place just like you would with DIN mount terminal blocks (or any other DIN rail mount component).
Review: Great 10 amp circuit breaker! - Great Din Rail 10 Amp Circuit Breaker! I needed this ten amp circuit breaker to protect my High-Power Temperature Control Switch for an overload from a 6 amp high velocity attic exhaust fan. If the fan malfunctions, the circuit breaker will trip, and save the Temperature Control Switch from damage. This breaker attaches to the DIN Rail (not included) with a plastic clip at the top and bottom edge of the module. With a small screwdriver, slide the plastic tabs away from the module to disengage the circuit breaker from the module. The circuit breaker switch feels good, and operates smoothly. The screw-down terminals clamp onto the wire with good force. Here are a few things that I noticed about this circuit breaker: When the switch is DOWN (in the OFF position), the power indicator window is GREEN. (Think GREEN = circuit is safe to work on). When the switch is UP (in the ON position), the power indicator window is RED. (Think RED = Danger - Circuit is ENERGIZED and it is NOT safe to work on). I could not find any safety ratings from the UL (USA) or CSA (Canada). There IS a rating for EC (Europe). This is good enough for my purposes, but if you do not live in Europe, you might need to check with your local electrical inspector to confirm the EC rating is accepted in your location. All-in-All, I am very pleased with this 10 amp circuit breaker.
