MX Rocker Switch with Built-In Circuit Breaker, 15A-250V SPST-3P (MX-1908)

A separate fuse or breaker alongside a main power switch is the usual way to get both switching and overcurrent protection, but the MX-1908 folds both jobs into a single rocker, tripping its internal 15A breaker and cutting power automatically if the circuit draws too much current, then resetting with a flip once the fault clears. That combination saves panel space and wiring compared to mounting a switch and a separate breaker side by side.
