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 480 Vac and 32 amps protected by
a circuit breaker
100 kA on any system up to 480 Vac and greater than 32 amps protected
by a circuit breaker
100 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!

Note: This table lists the maximum SCCR of the component when protected by any circuit breaker or fuse. If the maximum component SCCR
is 100 kA and a 25 kA rated circuit breaker is used, then the system will be 25 kA as the circuit breaker becomes the weakest link.
For more information on high-fault component short-circuit current ratings
including maximum fuse and breaker ampacities, please refer to the TeSys Motor
Control Solutions for the North American Market data bulletin (8536DB0901).

Power terminals can be protected against direct finger contact by the addition of shrouds and/or insulated terminal blocks, to be ordered separately
(see page 113).
For use with D25-D38 contactors, order spacer clip (part number W816366180111). See page 137.
These overloads are available without single phase sensitivity. To order, change the LRD prefix to LR3D and add A1 to the end of the number.
Example: LRD1508 becomes LR3D1508A1
