Curran's clash with the umpire took place during a practice session on December 11.
The England international has been charged with a "Level 3" offence under the Cricket Australia Code of Conduct, prompting the team to hand suspension on December 21.
Curran's clash with the umpire took place during a practice session ahead of Sixers' match against Hobart Hurricanes on December 11 in Launceston.
Cricket Australia said Curran completed a practice run-up in which he ran onto part of the pitch and the umpire instructed him not to. He moved to the opposite end to complete another practice run-up but the umpire took a position next to the stumps, blocking the player from approaching the pitch.
"Curran was seen in the footage gesturing to the umpire to move away... He then attempted to perform a practice run up and run at pace straight towards the umpire who stood in the bowling crease facing Curran," CA said in a statement. "The umpire stepped to his right to avoid the risk of collision."
After the announcement of the ban, 7Cricket released a video, in which Curran can be seen violating the rules despite being warned by the umpires.
Tom Curran will miss out on matches against Adelaide Strikers, Melbourne Stars, Sydney Thunder and Brisbane Heat due to the ban.
