1 C7 Series C7 Special Use designed and labeled for specific industrial applications The C7 line includes a number of contactors designed and labeled for specific industrial applications. In most cases, these devices are UL and CS approved for these specialized uses. Where appropriate, contactors also carry approval by specific industry associations such as RI (ir Conditioning and Refrigeration Institute). Hydraulic Elevator Wye-Delta Special Use Hydraulic elevator duty contactors HVC rated contactors Lighting contactors NEM size labeled contactors Most industrial wye-deltas consist of three contactors with interlocks but Hydraulic Elevators are a special application. Hydraulic Elevator wye-deltas consist of a pair of mechanically linked contactors with sufficient auxiliaries for electrical interlocks. The wye-delta is similar to a reversing contactor but the power wiring is different. We offer Hydraulic Elevator contactors with a choice power wiring inter-connections for ease of installation, or without power wiring inter-connections, allowing the elevator serviceman to make use of the existing power cables. This convenient selection of a complete assembly saves time and effort in the field. CNX Special Purpose CNX Special Purpose are rated by FL & LR as well as resistive current rated - primarily to meet the demands of the HVC and compressor markets. CNX contactors have all the flexibility of a C7 contactor like easy coil change out, DIN rail mounting and field installable auxiliaries as well as mechanical interlocks not normally associated with true definite purpose contactors. CNX contactors may also be combined with CEP7 or CT7N overload relays to make a special purpose starter. CNX starters are cul rated and labeled as well as RI (ir Conditioning and Refrigeration Institute) approved. CN7 and CN6 NEM size labeled contactors CN7 and CN6 contactors are UL Listed in accordance with NEM standards publication ICS-2. CN7 and CN6 contactors are UL labeled for application under IEC KW, as well as NEM Size, for specified horsepower at various voltages. CN7/ CN6 contactors have been purposely selected larger to increase the life of the device. Only the devices listed here are available with the NEM size on the UL label. CN7/CN6 NEM sized contactors may be combined with all Sprecher + Schuh overload relays to make a NEM sized starters. 40

Series CL7 Lighting Compact contactors for North merican lighting applications Sprecher + Schuh C7 and C6 contactors can be used to control a wide variety of lighting loads.

6 Series CL7 Lighting Compact contactors for North merican lighting applications Sprecher + Schuh C7 and C6 contactors can be used to control a wide variety of lighting loads. These contactors are well suited to handle the high inrush currents typical of this application as well as other non-motor (resistive) loads. Lamps can basically be divided into three categories: Tungsten Filament Lamps - General purpose incandescent - Special purpose incandescent - Infrared - Sodium Iodine Discharge Lamps (with Ballast) - Fluorescent lamps - Mercury vapor - High/low pressure sodium - Quartz - Halogen metal-vapor Mixed Light Lamps In application Electrically held contactors Electrically held contactors are available for use where the control signal is activated by a timer or other maintained electrical signal. The coil is energized as long as the contactor is closed. This design is well suited for applications where lights are operated frequently or where the control panel is in a remote location. CL7 The tungsten filaments of incandescent lamps have a very low ohmic resistance when cold. s a result, the closing current is very high but also very short. The closing current of discharge lamps (lighting with ballast) is highly inductive (due to series-connected transformers or chokes), and its duration depends on the lamp type. Mechanically held contactors In general, North mericans refer to Lighting Contactor ratings in amperes without distinction between incandescent or ballast type of load. The lighting contactor selection table provided on the following page is for North merican use, so ratings are selected for mixed lamp loads which account for the higher incandescent inrush. Mechanically held contactors are available for applications where quiet operation or critical lighting is required, i.e., institutions, hospitals and residential/commercial areas. fter the contactor closes, the voltage is disconnected from the operating coil and the contactor is held closed by the mechanical latch. Built-in clearing interlocks allow control from either a momentary or maintained pilot device for the separate pull-in and release functions. Europeans usually separate the values for incandescent from discharge (ballast) lighting. Both values are provided in the technical section of our general catalog and may be more appropriate for those applying by CE standards. CL are labeled and UL approved for lighting applications 45

Contact your Sprecher + Schuh representative. See catalog page C38 for enclosed lighting contactors. Description The CL7 electrically held contactors and CVL7 mechanical held contactors are cul rated and labeled for tungsten and ballast lighting duty applications at 20, 30, and 60 amperes respectively. The C6 contactors shown are selections based on available technical data. These C6 units do not bear a cul rating for use as a lighting contactor. Operation of Mechanically Held Contactor with ON-OFF Pushbutton Catalog number CVL7 consists of a CL7 contactor with CV7-11 mechanical latch. Depressing the ON button energizes the L coil and the contactor closes. The mechanical latch locks the contactor in the closed position. The L coil is then de-energized by the coil, clearing contact UL (Terminals 65-66) to remove voltage. Depressing the OFF button energizes the UL coil, and the mechanical latch releases the contactor. The UL coil is immediately de-energized by the coil clearing contact L (Terminals 13-14) to remove voltage. The contactor is now open.
