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.

Automatic Carton Folding and Gluing Machine Yong Xiao
The carton folding and gluing machine is able to complete paperboard feeding, folding, gluing, pressing, shaping, and other steps automatically. Thus, the carton making process requires few workers, which helps save land occupation space and also largely improves production efficiency and reduces defective products caused by human factor.
The machine is mainly composed of the vacuum paperboard feeding unit, gluing and folding unit, as well as the counting and stacking unit. Except variable frequency motors, all other motors are all of Taiwain CPG brand. The maximum gluing speed is up to 130m/min and the average speed is 100m/min. The high working efficiency also helps reduce production cost.

Main Three Parts
1. The paperboard feeding unit of the automatic carton folding and gluing machine is applicable for bended cardboard as well. With high grade electromagnetic clutch, the unit can be independently controlled to assure simple and convenient operation. It adopts imported wearing resistant rubber belt for paper delivering.
2. The gluing and folding unit is designed with easy-cleaning stainless steel gluing rollers to assure uniform glue coating and avoid glue waste. The glue quantity can be electrically controlled as well. Meanwhile, the unit comes with a cardboard position correction device, and a paperboard creasing machine with adjustable creasing wheels. It is applicable for cardboards with thickness between 2mm and 8mm. The secondary creasing machine is also available to offer the second time creasing to some paperboards with unqualified creasing at the first time.
3. The counting and stacking unit for the automatic carton folding and gluing machine is digitally controlled, and supports data input without stopping the machine. In addition to automatic, accurate counting function, the unit also offers position correction function. The end products are pneumatically collected, fast and accurate.
Electrical Control System
1. The electrical system design of the machine conforms to European industry standard. The automatic carton folding and gluing machine comes with a color touch screen panel, and is controlled by Panasonic PLC controller, which reveals our user friendly design philosophy and simple equipment operation. The touch screen control panel and PLC controller are available with interfaces for future system upgrading.
2. The main motor speed is variable frequency controlled. The HOLIP VFD ensures smooth and steady motor operation, and helps reduce about 30% electricity consumption. It can also effectively protect the motor. When there is overheat, over current, over voltage, or low voltages conditions, the VFD will send out alarms and stop working. Corresponding alarming codes will also be displayed.
3. The contactors for motor control are all acquired from Siemens, and are additionally mounted with thermal overload relay, so as to protect the overloaded motors.
4. The connection wires are all connected by aviation plugs, assuring convenient maintenance, as well as simple connection and disconnection.
5. The front and rear ends of the automatic carton folding and gluing machine are both designed with operation buttons, allowing operators to operate the machine at either end. Made of stainless steel plate, the operation button panel is aesthetical and durable. With both graphic and text to describe the function of buttons, the button panel is easy to use.
