The WCS4-20B has four protected outputs with self-resetting circuit breakers and is capable of handling up to 12 A (288 VA) of total
load. Fuses provide a greater degree of protection for the unit because they are faster acting and more precise. Circuit breakers
will self-reset when the fault is corrected, eliminating the need for replacing fuses. However, the amount of current required to trip a circuit breaker can vary as much as 100 percent, depending on temperature. In the fused models, the values of fuses can be changed depending upon the specific current requirements of the equipment connected.
It’s in fair condition, missing a couple fuses & screw.
