Ever since the introduction of E62-3HF, our three-phase filter capacitor range with terminals and internal wiring optimized for high frequency filters, we had been concerned about the limitation to 3x56A dictated by the CAPAFIX S terminal. This deficit has now been overcome by CAPASTUD: our new three-phase stud terminal is rated up to 100A per phase and as well-suited for high frequency currents as the S and Z terminals in CAPAFIX design.
Check the latest edition of the “E62-3ph/3HF” brochure for details. 
New design can be identified by current (80A or 100A) and case design MB.
