1 TeSys IEC Contactors and Overload Relays Making High-Fault Short-Circuit Current Ratings Simple Schneider Electric is an industry leader in IEC contactors and overload relays, and is recognized as the market leader in quality, durability, and product development. The latest development in the TeSys family of IEC contactors and overload relays is component high-fault short-circuit current ratings (SCCRs). TeSys K and D Contactors SCCRs identify the level of fault current that a component or assembly can safely withstand. Without knowing the available fault current and SCCR, it is impossible to determine if components or equipment can be safely installed. The new high-fault component SCCRs are available for all TeSys K and D contactors and overload relays, including the TeSys D solid-state overload relays. Component ratings provide the flexibility to choose the desired level of protection, up to the rated maximum, and use it without the need for specific tested combinations and confusing tested combination spreadsheets. Component ratings are available when using either fuse or circuit breaker protection. TeSys High-Fault Component Short-Circuit Current Ratings: TeSys K and D Overload Relays 65 ka on any system up to 80 Vac and amps protected by a circuit breaker 00 ka on any system up to 80 Vac and greater than amps protected by a circuit breaker 00 ka on any system up to 600 Vac protected by Class CC or J fuses And the best part about component ratings? You know you have the right SCCR when you see it on the label! Make the most of your energy SM

SCCR (ka) [] Ratings apply to circuits with voltages no greater than those listed and are subject to maximum breaker and fuse ampacities. See data bulletin 856DB090 for ampacity limitations. [] When protected by any circuit breaker, including thermal-magnetic and magnetic-only. [] When protected by any Class J or CC time-delay fuse (Class CC applicable up to 0 A only). [] Overload relays with Everlink termination direct mount to D0A to D65A only. [5] Direct mount to old D style D0 to D65 (no Everlink terminations) and to D80 only. Note: This table lists the maximum SCCR of the component when protected by any circuit breaker or fuse. If the maximum component SCCR is 00 ka and a 5 ka rated circuit breaker is used, then the system will be 5 ka as the circuit breaker becomes the weakest link.
