They are used in conjunction with 3RT20 contactors to form motor starters. Trip class: The 3RU21 overload relays are designed in accordance with trip class 10, i.e. trips in less than 10 seconds at 6 times the trip current setting (FLA). The 3RU21 thermal overload relay is set by adjusting to the rated motor current with a setting dial. The range on the setting dial is calibrated in amperes.
