It's a panel-mount component for remote switching of lighting, heating, or small motor loads in commercial and industrial control cabinets — think contactor-style duty but in a compact DIN-rail footprint. The 16 A rating is the thermal continuous current through each NO pole. For resistive loads you can run the full 16 A; for inductive loads derate per the manufacturer's switching curve. ## Deployment context The compact width — typical for a 16 A remote switch — saves rail space compared to a full-size contactor. Terminal design accepts up to 6 mm² conductor, so it handles the incoming feed for a sub-distribution board or a lighting contactor panel.","metaTitle":"5TT5542 SENTRON Remote Control Switch, 16A 2NO 110V","metaDescription":"SENTRON 5TT5542 remote control switch, 16A 2NO, 110V AC/DC.
