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!

Ratings apply to circuits with voltages no greater than those listed and are subject to maximum breaker and fuse ampacities. See data
bulletin 8536DB0901 for ampacity limitations.

When protected by any circuit breaker, including thermal-magnetic and magnetic-only.
[3]
When protected by any Class J or CC time-delay fuse (Class CC applicable up to 30 A only).

Overload relays with Everlink™ termination — direct mount to D40A to D65A only.
[5]
Direct mount to old D2 style D40 to D65 (no Everlink terminations) and to D80 only.
[1]
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.

Class 10 with Ring-Tongue Terminals for LRD01 through LRD35 (load side terminals only)
Select the appropriate overload relay with screw clamp terminals from the table above and add 6 to the end of the reference.
Example: LRD01 becomes LRD016.
Thermal Overload Relays for use on single phase loads
Class 10 with connection by screw clamp terminals
Change the prefix in the references above from LRD (except LRD4kkk) to LR3D. Example: LRD01 becomes LR3D01.
Thermal Overload Relays for use on 1000 V Supplies
Class 10 with connection by screw clamp terminals
For relays LRD-01 to LRD-35 only, for an operating voltage of 1000 V, and only for independent mounting, the reference becomes LRD33 A66. Example:
LRD12 becomes LRD3312A66.
Order an LA7D3064 terminal block separately; see page 137.
(1) These are special separate mounted versions of the LRD43 overload relays for the LC1D115 and D150 contactors. Part number includes overload
relay, terminal block and 6 connectors (unit is not UL/CSA approved).
(2) When used with D25-D38 contactors, order spacer clip (part number W816366180111). See page 137.
