Abstract
A cabinet (1) for electrical switchgear is published. The cabinet (1) is provided with a top wall (2) which has at least one area (3) which can be bent out about a bending line (4) to form a pressure-relief opening. To reinforce the cabinet (1), the top wall (2) is connected to adjacent cabinet parts over its complete circumference. The area (3) is bounded all the way round by cuts (5). The cuts (5) are interrupted only by bendable cut-free points (5a), arranged in the bending line (4), and by cut-free points (5b) arranged in a cutting line (5) positioned parallel to the bending line (4), the said cut-free points being designed as safety points. <IMAGE>
