15-473: Is different from Wikidata All article disambiguation pages All disambiguation pages Utilization categories The utilization categories category for low-voltage switchgear defines the characteristic operating conditions for switchgear such as contactors, circuit-breakers, circuit-breaker-fuse units, contactor relays, etc. These devices are dimensioned for different electrical loads and for different operating conditions. The characteristic of
20-453: The load to be switched or controlled determines the requirements for the switchgear and its correct selection for the intended application. In particular, the stress on the switching path caused by current and voltage during switching on and off is of enormous importance. For example, the switch-on and switch-off current at resistance load corresponds to the continuous operating current, while, for example, squirrel cage motors consumes multiple of
25-453: The rated operating current during switch-on and in the acceleration phase. Contact load in amperes for heaters (AC1) and motors (AC3) can be found directly on the contactor. The "Utilization category" are mainly categorized in IEC 60947 in the following volume: In addition, IEC/EN 61095 also defines categories for "household and similar applications".
