Contactors DIL: Efficient Solutions for the Motor …

1 106 Contactors DIL: Efficient Solutions for the Motor FeederThe identifier for the new contactor generation is the green print. The innovationsare already partly known as they have been integrated into the series on anongoing basis over the last few years. The Contactors up to A have beenextended with plug-in accessories such as Motor filters and solder pin starters in the size range can also be plugged-in. The necessary openingshave been perfectly enclosed just as the entire contactor to assure perfectoperation. An even higher level of operational safety is now guaranteed by thenew knurled contacts for the auxiliary contacts.

2 The Contactors are becoming more Efficient , particularly due to the new Eco typesfor , 38, 72 and 170 A, as well as through the many innovations with themotor starters, for example, such as 14:31 Uhr Seite 106 For Moeller Electric Sales and Support call (866) 595-9616107 Contactors DIL MWith the same dimensions for AC andDC Contactors , planning andengineering can be carried out witheven greater efficiency. With only fourcomponent sizes covering the ratingrange up to 170 A, engineering is madeeven key benefit with Contactors up to 38 A is that the auxiliary contact isalready built in, and the DC contactorsinclude a suppressor circuit up to 170 15 A, the DC Contactors have anelectronic drive that removes the needfor coupling relays.

3 With all these extrasalready included in the Contactors , your costs are clearly reduced. Contactor relays DIL AThe new auxiliary contacts DIL A perfectly complement the new motorcontactors DIL M. A wide range of auxiliary contacts specially designed forthe contactor relays ensures optimumsolutions and reliable overload relaysOverloads relays ZB protect the motoragainst phase failure or overload. Theirauxiliary contacts switch the Motor contactor off, and signal the relays are suitable for protectingEEx e-motors according to the ATEX 100a operation requires the components used to have a high level of operational reliability.

4 That's why contactorsDIL M offer not only offer high lifespan values for standard AC-3 operation, but are also ideally suited fordemanding AC-4 Motor inching applications. This increasessafety even when machines and plants are being reset or refitted. Active safety features are inherent in these devices:interlocked opposing contacts, isolation and protectionagainst direct contact are worldwideMachine and panel builders alike are looking for economicalsolutions for low-voltage switchgear Contactors DIL M and overload relays ZB are ideal for integrating in complete systems, thus enabling considerablecost savings.

5 In many places, coupling levels are completelyunnecessary since intelligent electronics take over this low pick-up and sealing power means that smaller transformers can be Relays and 14:32 Uhr Seite 107 For Moeller Electric Sales and Support call (866) 595-9616108 DCDCACThe new electronic timer modules DIL M32-XTE are connected to the front of the new Contactors DIL M7 toDIL M32, DIL MP20 and DIL A. Thus asimple contactor control with a timerfunction can be created which does notrequire a higher level PLC, or for caseswhere a PLC would be on-delayed, off-delayed and star-delta functions allow a large rangeof wiring using spring-loadedterminations Moeller provides proven quality withtension clamp terminals.

6 Numeroustests have proved that Contactors andmotor-protective circuit-breakers arejust as securely wired in this way as byscrew connection even in stronglyvibrating machines. But wiring workusing tension clamp terminals is verymuch quicker to do. The main currentpaths on PKZM 0 and Motor contactorsup to 12 A all use spring-loaded terminals. The sundries for terminationare always available for both screw andtension clamp and DC Contactors :With Same Frame Size For Simpler EngineeringThe new Contactors DIL M are significantly more compact than theirpredecessors, even though, up to 32 A,the auxiliary contact is included.

7 Theadvantage of this is particularly strikingwith the DC Contactors that now arethe same size as their AC makes everything easier, , engineering and fitting,without having to alter the controlsystem, even if the control current has to change for another same range of accessories areused both for AC and DC compromise where terminationreliability is concernedDIL Contactors up to 150 A have boxterminals with two clamping cham-bers, allowing unequal cable cross-sections to be terminated absolutelysecurely. This makes wiring easier andcuts down on associated 14:32 Uhr Seite 108 For Moeller Electric Sales and Support call (866) 595-9616109 This reduces the cost of your control panel The space-saving is achieved not just by the reduced componentdimensions, but also due to the lower heat dissipation that,particularly with the DC Contactors , helps keep the cabinetsize down and saves the cost of a fan.

8 The significantly reducedsealing consumption achieved by innovative, electronic drivesmakes this possible. The Moeller DC Contactors from 17 up to65 A have a sealing consumption of only Watt, even thoseat 170 A only use Watt. This also results in lower powerconsumption for the whole installation. Electronic-compatible auxiliary contactOften very small signals have to be switched for indicating thestate of the contactor to the PLC. In order to increase the ofthe feedback signal Moeller has developed a new auxiliarycontact with a make and break contact which is suitable forswitching small currents with low voltages.

9 The DILA-XHIR11auxiliary contact is tested for contact reliability at 1mA and17 VDC. The failure rate is less than 1 failure in 100 millionswitching operations. The auxiliary break contact is designed as a mirror contact sothat it can be used in safety applications as feedback benefits of the electronically controlled driveAll DC Motor Contactors with DC actuation from DIL M17have an electronically controlled drive that offers the follo-wing advantages: Significantly less heat dissipation due to reduced sealingconsumption Smaller control transformers because of lower pick-up consumption Direct actuation from the PLC without coupling contactorsup to 32 ASwitching Contactors directly from the PLCThis is a feature that is becoming increasingly more popularand is primarily made possible by the limitation of the DCpick-up power.

10 Moeller's new Contactors DIL M up to 32 A can be switched directly from the PLC using A DC additional coupling relay thus becomes unnecessary, andthis also applies to expensive and cumbersome relay new Contactors DIL M thus enable the use of more compact switching cabinets and inexpensive Relays and 14:32 Uhr Seite 109 For Moeller Electric Sales and Support call (866) 595-9616110 , 3-poleAC-3 380 V/ 400 VAC230 V 50 HZ 240 V 60 Hz, 110 V 50 HZ 120 V 60 Hz, 24 V 50/60 HZ, DC24 VAC384041 IeAPkWContactsPart no.
