Crane Control Class 7004Type M Line-Arc DC ContactorsAPPLICATION DATARatings are based on 40 C (104 F), per NEMA standards.MountingThe Type M contactor with its insulated base can be mounted directly on uninsulated steel panels, angleiron frames, etc. The contactors are completely front-connected.WiringSize 1 through 5A Type M contactors have a wire accessway in the base for convenient out-of-the-wayrouting of cables and control wires. Size 6 through 8 contactors have a flat mounting base. Powerconnections to the NEMA Sizes 3 through 8 contactors can be made from either side.Coil DataDC operating coils are designed in accordance with NEMA standards to withstand 110% of ratedvoltage continuously and to operate the contactor successfully at 80% of rated voltage. Standard coilvoltages are 120 VDC and 240 VDC. For other available coil voltages, refer to the Class 9998 Coil DataCatalog Sheet.AC to DC Control Voltage ConversionTo control the DC contactor coil from a 120 VAC supply, order each single pole contactor with 120 VDCcoil or for double pole contactors, order each contactor with a 60 VDC coil.Connect the rectifier and suppressor (MOV) as shown.120VAC(–)( )105VDCMOVRectifier part no. is 27907-34220 (800 PIV, 30 A)CRANE CONTROLCLASS 7004RECTIFIERMOV part no. is 52906-028-59Double Pole ContactorsDouble-pole, normally-open contactors can be built by ordering two single-pole, normally-opencontactors with half-voltage operating coils and one tie bar kit. The two coils must be connected inseries.User Modification KitsA number of Class 9999 user modification kits are available for use with Type M contactors. Powercontact tip parts kits are listed under Class 9998.Maximum Number of Accessories and Accessory CombinationsFor single-pole, normally-open contactors, two electrical interlock kits and any one of the following: Two mechanical interlock kits One tie bar kit and one mechanical interlock kitFor single-pole, normally-closed contactors, two electrical interlock kits1/17111 2003 The Electric Controller & Mfg.

Crane Control Class 7004Type M Line-Arc DC ContactorsAPPLICATION DATAElectrical InterlocksControl circuit interlocks are available in units of one normally open and one normally closed contacts.On each single pole normally open and normally closed contactor a maximum of two interlock kits canbe mounted. Interlock kits include the movable and stationary contacts plus all necessary hardware formounting.Electrical interlocks are rated in accordance with NEMA Standard ICS- 2-125 (A600 and N600 TableRatings).Class 9999 Type MX11Electrical Interlock BreakMakeBreak102.22.21.11.10.40.4DC Maximum Make and Break Current Amperes m Make and Break Current Amperes 125V250V600VMake and break ratings apply for double-throw contacts only when both the normally open and normally closed contacts areconnected to the same polarity.Mechanical InterlockCRANE CONTROLCLASS 7004A horizontal mechanical interlock is mounted between two single pole normally open or double pole tiednormally open contactors mounted side by side. This interlock prevents the two contactors fromoperating simultaneously.LugsClass 9999Type MM2MechanicalInterlock KitType M contactors are furnished without power lugs. A kit is available consisting of lugs and hardwarefor mounting on Size 3 and larger contactors. No power lug kits are available for the NEMA Size 1 and2 contactors. These contactors are designed to use lugs supplied by the user.Lug Wire Capacity Lug Type Minimum Wire SizeMaximum Wire SizeML1Number 8Number 00ML2Number 0300 MCMML3250 MCM500 MCMContains four clam shell type lugs. For copper conductors only.Power Contact TipsA Class 9998 power contact tips part kit consists of movable and stationary contact tips with necessarymounting hardware for two single pole contactors. Consult Catalog Section 9998 for additionalinformation.Copper contact tips are standard. Silver-faced contact tips are available and are recommended forapplications where the contactors remain closed for long periods of time. Silver-faced contact tips arestandard on crane manual-magnetic disconnect switches.Tie BarApplications requiring double pole Type M contactors can be met by supplying single pole normally openonly contactors with tie bars. The tie bar is made from an insulating material and connects the armaturesof the contactors together. For double pole contactors, it is recommended that the operating coils beconnected in series. Each coil should be rated for one half of system voltage. See Catalog Section 9999,page 160, for additional information.112 2003 The Electric Controller & Mfg. Co., LLCAll Rights Reserved1/17

Crane Control Class 7004Type M Line-Arc DC ContactorsAPPLICATION DATAClass 9999 AI1 Arc SuppressorThe Class 9999 AI1 arc suppressor is designed to reduce arcing of pilot devices in DC inductive controlcircuits of 250 VDC or less.TypePriceAI1360.The AI1 arc suppressor will limit the inductive voltage surge to a maximum of 600 VDC when applied inaccordance with the application chart. When applying the arc suppressor to a circuit, two factors mustbe considered, the current drawn by the inductive load and the number of times per minute that the loadwill be interrupted. Once these two factors are determined, the application is checked against theapplication chart. The chart shows the maximum interruptions per minute that the arc suppressor canhandle at a given current. As long as an application falls below the curve, the arc suppressor will handlethe load. The arc suppressor is connected in parallel with the inductive load and is in the circuit at alltimes.Application Chart for AI1 Arc Suppressor60504030L 11HCRANE CONTROLCLASS 7004PERMISSIBLE INTERRUPTIONSPER MINUTEClass 9999Type AI1Arc Suppress2010L 20H0.4 0.5 0.6 0.7 0.8 0.9 1.0 1.1 1.2 1.3 1.4CURRENT IN AMPERESApproximate Dimensions And WeightsClearance for (2)1/4" mtg. screws4.381113.75951.65 3.0042760.256.31.00251.93492.2557Dual Dimensions: inchesmmNet Weight – 1 lb (0.45 kg)Ordering Information Required:1.
