SIRIUS 3RU2 Overload Relays
The SIRIUS 3RU2 thermal overload relay mounts directly under a 3RT2 contactor of the same size and trips the contactor coil when the motor draws too much current. We list 3RU2 relays in sizes S00, S0, S2 and S3, Class 10, each with its setting range in the title (for example 3RU2126-4FB0: 34-40 A, size S0).Choose the range that contains the rated current of the motor, and make sure the relay size matches the contactor size (3RU211 for S00, 3RU212 for S0, 3RU213 for S2, 3RU214 for S3). Send the contactor order number and motor current and we confirm the right relay.Prices are quoted per order on WhatsApp or by email: send the part number, quantity and delivery country. Single units and bulk orders are both welcome, all parts are original with a 1-year warranty, and air delivery takes 5 to 7 days from dispatch (terms).
