The fuselage of the jets will be made by the Northern Irish division of company.
There is also the possibility that an order for another 30 aircraft could be on the cards, taking the total value to more than £2bn.
It follows on from last week's record-breaking order for the company, and Bombarier said it will further help guarantee Belfast jobs in the near term.
"This order is a further vote of confidence by customers in Bombardier's products, and in the skills and capabilities of our workforce here in Belfast," a statement said.
"Bombardier Belfast is responsible for the design and manufacture of the centre fuselage, engine nacelles and composite wing components for the CRJ900 NextGen regional jet.
"Orders such as these over the past week are helping to maintain our current manpower levels and secure the long-term future of our design and manufacturing operations in NI."
