A tandem circuit breaker is a two-single-pole circuit breaker that takes up the space of a single circuit breaker on a panelboard. It's also known as duplex, slimline, twin, half-height, half-inch, double and wafer breakers, depending on local customs. 

Circuit breakers are intended for switching and protection of your homes wiring from high temperatures caused by excess current higher than the rating of the wire. While thermal-magnetic circuit breakers are the key element for overload and short-circuit protection of your electrical system, there are potentially dangerous conditions that do not involve over current.
