Product Features

Under normal condition, the working principle of main thermostic bimetal in FTB1 SMCB is the same to the usual circuit breakers, it is used for overload tripping. when there is a short-circuit on a branch circuit breaker, the magnet core in the main current path would tilt the moving contact away from the fixed contact to break the circuit,thus producing the electric arc, and limiting the short-circuit current effectively.

In the maintime,the short-circuit current flow to the supplementary current path, a selective resistor and a selective bimetal are connected in series of the supplementary curret path, limiting the short-circuit current to a few hundred amps.

When the downstream circuit-breaker has tripped because of a short-circuit, the contact tips reclose automatically through a simple spring-type system,ensuring other unaffected branch circuits continue in operation.If a short-circuit occur between the FTB1 and the downstream circuit-breaker, another bimetal release enables short-time delayed tripping,ensuring the contact tips remain in the open position enabling isolating.

First of all I have now learned that the part that I called “power steering” Is actually the CRUISE CONTROL. Thank you all who noticed and corrected my misinformation.

I was having trouble with my ’91 Honda Accord starting. I would turn the key, the engine would crank, but it would not start. I was told to remove my battery cable for a few min to reset the computer. And voila! It started. This happened 3 times in a week.
After much researching, one solution kept coming up, the main relay assembly. It is the part that controls the signal to the fuel pump. It took very little time or tools. The part that was hard was getting to it. It was under the dash to the left of the steering wheel waaay up in the dash. It took some yoga moves, but I had it out and back in in about 35 min. I used a 10mm socket wrench with an extension and a small flat head screwdriver.
