That 20 A rating across both common line voltages means it handles resistive or lightly inductive loads like heater banks or lighting circuits without derating between 230 V and 400 V systems — one less variable when you're populating a panel that feeds mixed-voltage zones. ## Panel integration As an INSTA-series contactor, the 5TT5702-2 snaps onto standard DIN rail — the same 35 mm profile used across Siemens panel-building components. The two NC contacts are wired in series with the load; the 24 V AC coil pulls from a control transformer or dedicated AC supply. Keep the coil wiring separate from the power circuit to avoid induced noise on the control side during switching.","metaTitle":"5TT5702-2 INSTA Contactor, 2 NC, 20 A, 24 V AC","metaDescription":"5TT5702-2 INSTA contactor with 2 NC contacts, rated 20 A at 230/400 V AC, 24 V AC coil.
