Scope

This standard applies to electromechanical auxiliary contact assemblies assembled (or intended to be assembled) with overcurrent protection circuit breakers and residual current operated circuit breakers for household and similar applications (with or without overcurrent protection). The rated voltage of the auxiliary contact assembly shall not exceed 440 V AC and 250 V DC, and the rated current shall not exceed 10 A. Note 1: These technical requirements can also serve as a guide for auxiliary contact assemblies intended to be assembled with other switchgear for household and similar applications. Note 2: For any applications related to low-energy (low current and/or voltage) electrical devices, it is recommended to consult the manufacturer. For low-energy contacts, special recommendations can be found in IEC 60947-5-4.
