POLARITY-SENSITIVE PROTECTOR DEVICE

摘要

Disclosed is a voltage and current protector device (21) designed for insertion in connecting blocks (10). The current and voltage protection elements of the protector are mounted on a printed circuit board (26) which has a conductivepattern (60, 61, 64-70, 71, 72) on both major surfaces such that the elements can be mounted on either surface and the protector device (22) can be inserted into the top or bottom surface of a connecting block depending upon which surface the elements are mounted.
