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. 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. 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.
