Design is simple, inexpensive way to both applications is the use of "1" or application mode "2", 4kW/400V following PKZ M0 and DIL M contactor motor starter combinations consisting of 100kA short-circuit current can be controlled. No other circuit protection devices in series. Using standard components to ensure continuous operation of the machine according to IEC / EN 60947 standards, motor starters, by using methods of "1" and application mode "2." Classification criteria are based on the motor starter tolerance in the event of short circuit conditions. Two major applications of the motor starters can be a safe short-circuit breaking current. The only difference is that after a short-circuit current status of the starter. Consistent application mode "1" starter more economical, suitable for standard applications, allowing the short circuit current on the starter damage. Formed in the PKZ M0 motor starter, only need to check the status of contacts, because PKZM0 motor protection switch is always consistent application mode "2". PKZM 0 motor protection switch with a combination of DIL M contactors to provide two application modes of the motor starter. This can be one of the few standard components and meet the vast majority of applications. (Download: motor protection switch PKZ W1210 +1280-7432 CHN)
