What is SCCR used for?
Definition: Short Circuit Current Rating (SCCR) is a rating on components and assemblies representing the maximum level of short-circuit current that a component or assembly can withstand. This rating is used to determine compliance with NEC 110.10.
Why is short-circuit current important?
In essence, a short-circuit current rating gives a baseline for the fault current that a piece of equipment or individual component within the equipment can withstand for a specific amount of time, or until it clears the circuit with a fuse or the opening of a circuit breaker.
What does SCCR mean in electrical?
Short-Circuit Current RatingComponents that provide functions other than overcurrent protection, such as disconnects, power distribution blocks, motor controllers and others, are required to achieve adequate Short-Circuit Current Rating (SCCR) (NEC 110.10).
What is the SCCR of a circuit breaker?
A short-circuit current rating (SCCR)1 is the maximum current a device or system can safely withstand for a specified time (such as 0.05 seconds), or until a specified fuse or circuit breaker opens and clears the circuit. SCCR is usually expressed in kiloamperes (kA).
Are all power circuits required to have a SCCR?
As referenced in UL 508A and the NEC, industrial control panels that contain only control circuit components do not have to be marked with an SCCR.
What is SCCR protection?
In simpler terms, SCCR is the maximum short-circuit current an electrical component can safely withstand without causing a shock or fire hazard. In general, the SCCR rating for an electrical panel is based on understanding each electrical components SCCR rating in that panel.
Do Motors have SCCR?
SCCR applies to all electrical equipment, such as panelboards, switchboards, motor control centers and industrial control panels.
Is AIC and SCCR the same?
Note: The difference between SCCR and AIC is that AIC applies to overcurrent protection devices only, and the SCCR applies to the entire assembled device, which may use as part of its assembly overcurrent protection devices with an AIC rating.
Do transformers have SCCR?
All power circuits are required to have a SCCR with the exception of Power Transformers and Reactors, because voltage does not flow thru without restriction (UL508A SB4. 2).
What unit is SCCR?
The Short Circuit Current Rating (SCCR) states the maximum amperage (fault current) a component, enclosure, or unit can withstand during a short circuit event thereby limiting personal injury, damage to the premises, and damage to equipment.
Does a VFD have an SCCR?
Therefore the VFD's may have very high SCCR ratings, like 65kA or 100kA, which is primarily due to the ability of the fuse to achieve rapid quenching of any fault based energy release. With such high SCCRs it should not be a problem for our VFD panel to safely be applied to our circuit.
It is important to verify and improve short-circuit rating to remain in compliance
There are several problems with electrically powered equipment. One of them is a short circuit. However, prior to 2008 there was no definition of a short-circuit current rating in the NEC. Since this rating is now part of the NEC guidelines, it is important to verify and improve the short-circuit rating in order to remain in compliance.
How to improve the short-circuit current rating
There are a number of ways in which the current rating can be improved. The first step in the process is to have the equipment or component tested to ensure that it is in compliance. Determine the available short-circuit current at the part or point of installation to test compliance.
How to determine SCCR rating?
The SCCR rating of the motor control system is determined by examining the maximum ratings of the individual devices connected to the individual branch circuits. The device with the lowest rating becomes the limiting factor.
How to protect against short circuit currents?
To protect against short circuit currents, limited by an isolation transformer, the required current a fuse needs to clear instantly needs to be evaluated. To do this, the collective available short circuit current of the mainline and isolation transformer must be determined.
Why is SCCR important?
SCCR is important for the installation of industrial machinery and electrical panels in facilities. If this rating were to be ignored there could be significant risk of catastrophic equipment and component failure, putting workers at risk.
What does SCCR stand for?
What is Short-Circuit Current Rating (SCCR)? In a world filled with acronyms, you probably see a new one every day. Today’s is SCCR, which stands for Short-Circuit Current Rating (SCCR).
What is SCCR in electrical?
Simplified, SCCR is the maximum short-circuit current an electrical component can withstand without causing a shock and/or fire hazard. SCCR for industrial control panels is generally determined by the SCCR rating of all the components within an industrial panel.
Can an industrial control panel be installed where the short circuit current exceeds the panel's SCCR?
Industrial control panels cannot be installed where the available short-circuit current exceeds the panel’s SCCR. Therefore it is necessary to calculate the maximum SCCR that is present where the industrial panel will be installed. The available short-circuit current must be less than or equal to the marked SCCR.
