The SENTRON 5TT5523 is a remote control switch rated for 24 V AC/DC at 16 A with three normally-open contacts (3NO). It's designed for panel-mounted switching of lighting, heating, or other general loads where you need remote on/off control from a PLC or pushbutton station — the coil holds at 24 V nominal and pulls in reliably at the rated control voltage. The 3NO configuration means all three poles switch together, so it handles three separate single-phase circuits or a single three-phase load through one contactor-style package.
The 16 A rating at 24 V AC/DC governs the continuous current each pole can carry — sized for lighting banks, contactor coils, or small motor loads within that current envelope. The 3NO (three normally-open) contact arrangement means all three poles close when the coil is energized and open when de-energized, so it functions as a multi-pole relay. The 24 V control voltage is common across industrial panels, so it integrates directly with a 24 VDC PLC output or a 24 VAC control transformer without an intermediate relay.
Where it sits in the panel
As a SENTRON remote control switch, the 5TT5523 mounts on DIN rail inside a standard distribution or control panel. It occupies the same footprint as a contactor or relay of similar rating — no special cutout or bracket needed. The 3NO output terminals accept standard ring or fork lugs for load wiring up to 16 A per pole.
