Abstract

A circuit protector employs molded resinous parts including a base and a support frame structure. Advantageously the circuit protector support frame structure may include a medial plane frame providing space for two circuit protectors, one on each side of the frame and a common back plane mutually perpendicular to the medial frame and the base along one edge of the base. A cover fits over the support frame and base and snugly accommodates the base at its terminal edges except immediately along the back plane. The back plane is provided with a slot through the back plane in the vicinity of each pair of contacts which communicates to a space between the cover and the back plane of the base permitting venting of gases generated by arcing. Grooves are supplied in the medial plane frame and the back plane to accommodate edge flanges of an arc suppressing grid to hold the grid in place to bracket the contacts.
