Resistor — Resistors primarily limit current; protection devices interrupt circuits or respond to faults.

Overcurrent — Fuses break the circuit when excessive current flows, protecting against overload.

Opens the circuit — Circuit breakers interrupt the current flow to isolate the faulted section.

Relay — Relays sense faults and signal the circuit breaker to trip quickly.

Detect and interrupt earth leakage currents — RCDs protect against electric shock by detecting and interrupting leakage currents.
