Application:
3RU21 overload relays provide overload protection for three-phase inductive motors with
rated currents of up to 100A (75HP, AC-3,480V).
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.
