The 16 A rating holds at a power factor of 0.6, which covers the inductive load curve typical of contactor coils and small transformers — not just resistive heaters. The 230 V AC control voltage is line-powered, so no separate control transformer is needed if the panel already runs 230 V line-to-neutral.
