• the present invention relates to the field of electronic protection equipment, such as electronic protection circuit breakers, as well as the field of contact modules.
• An electronic protection circuit breaker may for example consist of an open or air circuit breaker, also frequently designated by the acronym ACB (Air Circuit Breaker).

To install this type of contact module in the electronic protection circuit breaker, it is necessary to disassemble various elements of the electronic protection circuit breaker and to make a certain number of electrical connections. This solution has the disadvantage of making it difficult to add a contact module to the electronic protection circuit breaker.
