This N-type unit is designed for panel-mounted load switching where a control signal from a PLC, timer, or manual pushbutton needs to energize or de-energize a circuit remotely — common in lighting contactor panels, HVAC sequencers, and industrial machine control cabinets. The 3NO configuration gives you three independent power paths that close together, so it can switch a three-phase motor directly or distribute a single-phase feed across three separate loads. Mounts on standard DIN rail. The 3NO contacts are rated for 16 A at 110 V AC/DC. Confirm the load type matches the switching capability.","metaTitle":"SENTRON 5TT5543 Remote Control Switch, 16A 3NO 110V ACDC","metaDescription":"SENTRON 5TT5543 remote control switch, N-type, 16A, 3NO, 110V AC/DC.
