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.
