Current Limiter

Current limiters cap how much current a circuit can deliver into a fault, holding the let-through energy below what the equipment downstream is built to survive. Sensitive circuits need one when available fault current exceeds a device's rating, when a short has already damaged more than it should have, or when a panel has to be protected without upgrading everything inside it.

 

As an authorized electrical distributor for multiple manufacturers, we stock ABB current limiters in a range of types and dimensions, so you can match the let-through rating the equipment downstream requires and hold fault energy inside what a panel can take.
