dil m low range moeller s dil m contactor series includes a completely new offering in the lower 7 to 150a range consisting of four frame sizes this range is the newest and most modern of any control manufacturer special advantages of going dc in addition to sharing the same frame size as ac contactors dc units of 17a and above also feature electronic drives that dramatically reduce pick-up and sealing consumption these drives produce several benefits · less heat is generated eliminating the need for a fan · smaller control transformers are required · contactors up to dil m32 can be directly actuated from plcs eliminating the need for a coupling relay these benefits lower your cost by consuming less power eliminating additional components and permitting higher packing density in the panel dc units to 150a also carry a built-in high-speed suppressor circuit eliminating the need for purchasing and installing a separate external suppressor again lower total cost and smaller panel space result for additional safety and convenience moeller s dil m dc contactors feature an expanded voltage tolerance beyond that specified by iec/en 60947 this accommodates a range of -30 to +20 for dil m contactors 17a and above it is one of the largest voltage tolerance ranges of any control manufacturer compact design for both currents conventional contactors designed for dc control applications can be up to 30 larger than their ac counterparts not anymore unique to moeller s dil m contactors ac and dc units are the same frame size throughout the entire range the reduced size means smaller dc panels than ever before this also means you can now design one panel for either ac or dc control without having to plan for a larger dc contactor easy to assemble coil terminals are located on the front of the new contactors to simplify wiring both two and four-pole auxiliary contacts snap on without tools units 40a and above accept both side and top mount auxiliaries for increased flexibility in addition devices up to 32a include built-in auxiliary contacts for increased economy with no additional space requirement +20 -30 positively driven contacts for additional safety auxiliary contact blocks for new dil m contactors are available with positively driven contacts for added safety in control circuit schemes positively driven auxiliary contacts insure that throughout the life of the contactor n.o n.c auxiliary contacts will never be closed simultaneously.
