FIELD: protective gear for electric circuits. SUBSTANCE: differential switch and circuit breakers are mounted in cases having two opposing narrow surfaces mounting input terminals and output ones as well as two opposing side walls by means of which cases abut against each other. Output terminals of switch are spaced apart through same distance as input terminals of protective devices so that these terminals can be connected to terminal strip mounted on same side as protective gear power supply. EFFECT: facilitated connection of switch terminals to terminal strip. 5 cl, 2 dwg
