The Siemens SENTRON 5TT5032-0 is an Insta contactor with a 2 NO + 2 NC contact configuration, rated for switching loads up to 400 V and 25 A. The coil pulls in on 230 V AC (also accepts 220 V DC), making it a direct fit for standard European panel supply circuits. At 2 modular width units (35 mm wide, 71 mm deep, 90 mm tall), it slots into a DIN-rail enclosure alongside MCBs and other modular devices — but the installation note calls for spacers between units to shed the 2.2 W per-pole heat loss, so don't pack it tight without ventilation gaps.
Integration Notes
Panel builders: the 2 MW footprint (35 mm) matches standard modular DIN-rail spacing. The IP20 finger-safe housing is fine for enclosed panels but not for washdown or outdoor exposure. Supplementary devices (auxiliary contact blocks, surge suppressors) can be added via the product extension interface. The 64 mm installation depth leaves clearance behind a standard 80 mm deep enclosure backplate.
