If wireshark already knows that the traffic is ssl protocol then

ssl.record.length > 2 and ssl.record.content_type == 21

should do the trick, given that other alerts are only 2 bytes long
A more generic filter should be

tcp.len>7 and ((tcp[12,20:2]==50:1503 and tcp[22]<=3)||(tcp[12,32:2]==80:1503 and tcp[34]<=3))
