Using Thyristors in Heating Applications
... To provide full protection for thyristor devices is not straightforward. In particular the use of HBC fuses (type gG or gL in Europe) alone will most probably not offer adequate protection against either overload or short circuit. Special semiconductor fuses (type aR) provide correct protection agai ...
