DIN-rail footprint and panel space
The 5TT5030-0 occupies 35 mm width by 90 mm height with a body depth of 71 mm and an installation depth of 64 mm — 2 modular width units on a standard DIN rail. IP20 rated, so it belongs inside a closed panel — no exposed wiring or live parts outside the enclosure.
Coil drive and contact configuration
Four normally-open (NO) contacts, zero NC contacts — the contactor pulls in all four poles together on a 230 V AC or 220 V DC coil (AC/DC actuation). Rated for 400 V AC maximum on the main circuit, 25 A — typical for resistive or moderate inductive loads in lighting or HVAC contactor duty.
Thermal management — spacer requirement
Each pole dissipates 2.2 W in hot operating state at rated current — Siemens explicitly requires spacers between units for heat dissipation; pack them tight without airflow and the internal temperature rise accelerates contact wear.
Sourcing and lifecycle
Part of the SENTRON series, designated as an Insta contactor. Quoted to order against BOM quantities; availability and current pricing confirmed at RFQ.
