In a non-circuit limiting system, no allowances are made to limit the amount of current that flows through the circuit. Because of this, the circuit has no set maximum current, and spikes can occur in the voltage flowing through the circuit.

What is non current limiting fuse?

For a fuse to be considered “current-limiting”, it must interrupt the circuit within 180 electrical degrees (one-half electrical cycle) after the fault occurs. ... In a non current-limiting fuse the fault current continues to flow until extinguished by the cycle of the supply system (zero crossing).

What is meant by current limit?

Current limiting is the practice of imposing a limit on the current that may be delivered to a load to protect the circuit generating or transmitting the current from harmful effects due to a short-circuit or overload. The term "current limiting" is also used to define a type of overcurrent protective device.
