1. Automatic entry automatic reset
2. Automatic entry non automatic reset
3. Commutative standby
Three steady operating positions
1. The grid power supply is making, the standby power supply is breaking.
2. The grid power supply is breaking, the standby power supply is making.
3. The grid power supply is breaking, the standby power supply is breaking.
Compact size, single structure, beautiful outlook, 33~630A available, convenient operation and long operating life, 2, 3, 4P can be supplied.
The transfer is drived by single motor. Single structure, reliable transfer, no noise and small wallop.
The switch is with electromechanical interlock protection, which can ensure the two power supplies working normally, no disturbance,
The switch can be along with load automatic transfer, on urgent situation, it can be transferred by handle.
Advantages comparative to other products:
1. The breaking capacity of the control protecting fuse is 50KA, which increases the distribution safety.
2. Theres interlock between manual and automatic operation, this can avoid the manual operation on the automatic operation.
3. When the executive handle of circuit breaker is broken, the contact is felted or the load is in problem( overload, short circuit), the ATS do not transfer, this is called the real electromechanical interlock.
4. The driving mechanism of MCB type ATS is changed from fork type to concave type, which solve the problem of the break of the long handle type MCB and the non-synchronization of MCB making etc. Thus strengthen the function of fast making and breaking, and enhance the mechanical life.
5. The wrong wire connection indication can be supplied. When the phase wire and zero wire is connected wrong, the sound-photo device will alarm, it ensures the reliability.
