The 4000 W incandescent lamp load rating tells you it handles tungsten inrush without welding the contacts — that's the spec that matters if you're switching a bank of lamps in a warehouse or production bay. The body is 3 modular width units wide (54 mm), 90 mm tall, and 71 mm deep — standard DIN-rail footprint for SENTRON gear. The manufacturer calls out that spacers are required between units for heat dissipation, so don't cram them tight on the rail; leave the air gap the datasheet expects. ## Contact arrangement and load handling Three NO poles handle the main load circuit; the single NC pole is typically wired as a feedback or interlock signal back to the PLC or control relay. Supplementary devices (auxiliary contact blocks, surge suppressors) can be clipped on, which is useful if you need to add a second feedback signal or a pilot light without replacing the whole contactor. At 3 MW units wide it occupies about 54 mm of rail space — plan your layout accounting for the required spacers between contactors.","metaTitle":"Siemens 5TT5841-6 SENTRON Insta Contactor, 3 NO / 1 NC, 230","metaDescription":"Siemens 5TT5841-6 SENTRON Insta contactor with 3 NO + 1 NC contacts, 230 V AC coil, rated 40 A at 400 V.
