It's a compact panel-mount contactor for resistive or moderate inductive loads — think lighting banks, heater circuits, or small motor contactor duty where a 2-pole make is enough. ## Panel fit and installation 18 mm wide (one modular width unit) and 71 mm deep — it snaps onto DIN rail and leaves the same 90 mm height as the rest of the SENTRON modular range. The spec calls out spacers for heat dissipation, so don't pack it tight against other heat sources without the recommended air gap. The 230 V AC coil means it pulls in on a standard line-voltage control circuit — no separate 24 V DC supply needed. The 400 V 25 A switching capacity covers most single-phase lighting or small three-phase loads; derate for inductive or incandescent inrush (the 1 000 W incandescent lamp rating gives a reference for that duty). Power loss is 2 W per pole in hot state — negligible for panel thermal budgeting, but factor it if you're stacking several contactors in a sealed enclosure.","metaTitle":"Siemens 5TT5810-0 SENTRON Insta Contactor, 2 NO, 230V AC Coi","metaDescription":"Siemens 5TT5810-0 SENTRON insta contactor, 2 NO contacts, 230 V AC coil, switches 400V 25A.

Depth is 71 mm vs 76 mm on the 5SL6006-7 — slightly shallower, so no clearance issue. The 5SL6006-7 is a miniature circuit breaker, not a contactor; functionally they are different devices, but the panel cutout and rail space are compatible."},{"question":"What is the switching capacity of the 5TT5810-0?","answer":"Rated to switch 400 V at 25 A, with a specific incandescent lamp load rating of 1 000 W.
