Abstract

An excess current thermal relay having one or more poles and arranged in a split housing, having a trip slide which is operated by one or more trip-bimetallic devices located in phase, which trip slide is designed in the form of a comb or ladder and slides in a guide provided for the purpose in the housing, the vertical play being adjustable by means of two adjustment elements (24) arranged at a distance from one another. <IMAGE>
