.2050.. • Less sensitive voltage drops due drop-out voltage of 55% the lower nominal value along with sag and dip immunity. The GAF contactor’s ability break 2000 voltage up 1000 derives from the use permanent magnets the arc packages. • Existing add accessories for A/AF range three pole contactors will fit the GAF contactors. • PLC interface with 100 for GAF/AF400. Flexible • Wide control voltage range (e. Silent • powered coil makes the contactor virtually noise free. • (508) rated 600 DC. Reliable • The GAF contactor based the well proven contactor. 100-250 AC/DC) means less versions covering the entire range. Easy • The external dimensions the GAF contactors are the same as corresponding contactors making easy order and install.Features and benefits Powerful • 1000 switching ratings (IEC). • Elimination contact bounce and chattering provides for increased reliability and service life. These features avoid the problems with contactor chattering and welding. Normal contactors can break to some extent but since they lack the permanent magnets they will not able break corresponding GAF contactor. 1SFC101004B0201 switching contactors. The magnets enable the contactor extinguish the powerful electrical arcs that arise between the contact surfaces when breaking DC.g. Efficient • The electronic coil interface reduces power consumption 5-10 times holding compared conventional contactors
