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.
Scope of use
It is primarily used in critical installations,for instance, office buiding, laboratory, theatre, museum, hotel, shopping mall, telecommunication, coal mine and shipping, chemical industry and metallurgy, industrial plants,medical and health care, bank and securities exchange,airport, underground express way, military establishment and similar loads that requires non-interrupted and reliable power supply.

Rap starts at 2:00. You can stop helping now.
This is the full presentation of Rebel XD’s incredible performance on Fox’s old show, Guinness World Records Primetime. I previously had this recorded on VHS along with almost all the Guinness episodes.
I’ve lurked around the internet and I’ve found this similar video, but it was dubbed in Italian and it was cut short so we would only see Rebel XD’s performance, so I decided to put the entire segment, from Cris Collinsworth’s intro, to the Court Reporter’s hilarious take on the rap. Enjoy.
Now with corrected closed captions! Now you can actually read and hear what he’s saying, so stop mashing your keyboards, you wonderful, beautiful stupid people.
