The win in Rotterdam means the Poles have all but secured a place for themselves in the final 16.
Poland have three victories in a row under their belt and will be looking for a fourth when they take on Montenegro in a group D game in Amsterdam on Tuesday.
Two days later the Poles face off against Ukraine.
Poland, managed by Belgian coach Vital Heynen, kicked off their campaign in the championship with a 3-1 win against Estonia on Friday. They beat the Netherlands 3-0 on Monday in their second game.
The tournament is being held in four countries: Belgium, France, the Netherlands and Slovenia. It started on Thursday and runs until September 29.
Poland are one of the world's strongest teams. They won the Volleyball Men's World Championships last year and are ranked No. 4 by the International Volleyball Federation (FIVB).
