That helps when you're squeezing it into a gland-plate area or a swing-panel where the rail isn't perfectly plumb. The coil terminals are screw-type, accepting 2x (0.5…1.5 mm²) or 2x (0.75…2.5 mm²) solid or stranded. Compared to the smaller S0-frame siblings like 3RT2015-2BB44-3MA0, this S2 contactor is physically wider (55 mm vs the S0's 45 mm) and deeper (174 mm vs roughly 140 mm). The S2 frame carries higher continuous ratings and larger main-contact gaps. If you're swapping an S0 part out of a panel, check the DIN rail space — the extra 10 mm width and 34 mm depth can conflict with adjacent devices or the enclosure back wall.","metaTitle":"Siemens 3RT2035-1NP34 SIRIUS Power Contactor, S2 Size, 55 mm","metaDescription":"Siemens 3RT2035-1NP34 SIRIUS power contactor, S2 size, 55 mm width, 174 mm depth.
