Does anyone know if seimens breaker ties (ecqth3) are approved to tie more than two breakers together?

JD, welcome to the forum! :)

For manual disconnecting, a handle tie is adequate, so two or three 1-pole breakers may be joined with a handle tie for multiple line-to-neutral loads.

For automatic operation, as in over-current tripping, an internal common trip is required, so a "real" 3-pole breaker is required for a line-to-line load.
