Bulletin S-C/S-C IEC Safety Contactors Overview/Product Selection Product Selection -Pole AC- and DC-Operated Contactors Bulletin S-C/S-C IEC Safety Contactors Mechanically linked N.C. auxiliary contacts Front-mounted auxiliary contacts Gold bifurcated Permanently fixed Protective cover to prevent manual operation Red contact housing foreasy identification Incorporates IEC -- Mechanically Linked symbol AC and DC operating coils SUVA Third-Party certification Bulletin S-C/S-C safety contactors provide mechanically linked positively guided contacts, required in feedback circuits of modern safety applications. The mechanically linked N.C. auxiliary contacts will not change state when a power pole welds. In addition, the gold-plated bifurcated auxiliary contacts are ideally suited for low-energy applications or feedback control circuits with multiple series-connected N.C. auxiliary contacts. Your order must include: cat. no. of the contactor specified with coil voltage code and, if required, cat. no. of any accessories and/or replacement coils.

Bulletin -K/-K, -C/-C, -D/-D, -G Electrical Life in Utilization Category Bulletin -C/-C IEC contactors are designed for superior performance in a wide variety of applications. When selecting IEC products, the user must give consideration to the specific load, utilization category and required electrical life of the application. The life-load curves shown here are based on Rockwell Automation tests according to the requirements defined in IEC --. Since contact life in application is dependent on environmental conditions and duty cycle, actual application contact life may vary from that indicated by the curves shown here. To find the contactor s estimated electrical life, follow these guidelines:. Identify the appropriate utilization category from the table below.. Choose the graph for the utilization category selected.. Locate the intersection of the life-load curve for the appropriate contactor with the application s operational current (I e ) found on the horizontal axis.. Read the estimated contact life along the vertical axis. Contact Life for Mixed Utilization Categories AC- and AC-: In many applications, the utilization category cannot be defined as either purely AC- or AC-. In those applications, the electrical life of the contactor can be estimated from the following equation: Lmixed = Lac/[ + Pac*(Lac/Lac )], where: Lmixed = Approximate contact life in operations for a mixed AC-/AC- utilization category application Lac = Approximate contact life in operations for a pure AC- utilization category (from the AC- life-load curves) Lac = Approximate contact life in operations for a pure AC- utilization category (from the AC- life-load curves) Pac = Percentage of AC- operations AC- AC- AC- AC- AC- Test Conditions Resistance Furnaces: Non inductive or slightly inductive loads Slip-ring motors: Starting and reversing Squirrel-cage motors: Starting and stopping of running motors Squirrel-cage motors: Starting, plugging, inching Soleniods: Contactors, valves and lifting magnets I e < A I e > A I e < A I e > A Making Breaking I/I e U/U e cosφ I c /I e U r /U e cosφ.................. I e Rated operational current I Making Current U e Rated voltage Ic Breaking Current U r Recovery voltage U Off-load voltage Plugging is understood as stopping or reversing the motor rapidly by reversing motor primary connections while the motor is running. Inching (jogging) is understood as energizing a motor once or repeatedly for short periods to obtain small movements of the driven mechanism. - Publication A-CAA-EN-P
