Can you use the same relays for fixed and withdrawable breakers and will the fault/arc flash times be the same?
Issue:
use of relay for fixed breakers
Product Line:
Harmony Electromechanical Relays
Environment:
Relays – Interface, Control and Measurement
Resolution:
Yes, you can use the same relay as long as it fits within the means of the low voltage box of the switchgear. Fixed switchgear will traditionally have a smaller low voltage box that could restrict the size of your relay, but not the capability of the relay. For example, a 751-amp arc flash relay can be used in either fixed or withdrawable switchgear.
