The 5TT5030-2 occupies 2 modular width units (35 mm wide) and has a depth of 71 mm (64 mm installation depth). The spec explicitly calls for spacers between units to ensure heat dissipation — that's not optional. At 2.2 W per pole in hot operating state, four poles carrying load will dump nearly 9 W into the enclosure. Stack them tight without gaps and you'll cook the coil.
The part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or price is published here.
Four normally-open poles means the contactor switches four independent load circuits, all closed when the coil is energized. With zero NC contacts, it's a make-only device — no break-before-make auxiliary on the same block.
Yes. The product extension installable supplementary devices flag is set, so you can add auxiliary contact blocks or other add-ons to the side or top of the contactor.
As a SENTRON catalog item, standard Siemens declarations (CE, UKCA, RoHS, REACH) are available on request. The IP20 rating and the 400 V / 25 A ratings are per IEC/EN standards typical for this class.
