Usually utilization category is mentioned in most of the switch gear, with the above contactor stating to be used under AC1 - resistive load & AC3 for motor usage In electrical engineering utilization categories are defined by IEC standards [ 1 ] and indicate the type of electrical load and duty cycle of the loads to ease selection of ...
The current rating of the contactor depends on utilization category. Example IEC categories in standard 60947 are described as: AC-1 - Non-inductive or slightly inductive loads, resistance furnaces; AC-2 - Starting of slip-ring motors: starting, switching-off; AC-3 - Starting of squirrel-cage motors and switching-off only after the motor is up ...

These components are deemed "well-tried components" and are listed in ISO 13849-2, Annexes A through D. Additionally, components that have been tested by the manufacturer and approved according to the relevant component safety standard, e.g., IEC 60947-5-5, are also considered well-tried. Since Category 1 is single channel, DC avg = NONE. CCF ...
Let's start with some cold water — the Cardinals have defended tight ends well this year and Henry doesn't offer much goal-line equity; he's stuck on one touchdown for the season.
