It snaps onto a 35 mm DIN rail per DIN EN 60715 and can be mounted in any orientation within ±180° rotation on a vertical surface, with ±22.5° tilt forward/backward — useful when you're squeezing it into a crowded panel. Coil inrush peaks at 65 A, steady-state draw is 3.5 VA at 50/60 Hz.
The 3RT2448-1NP30 is 70 mm wide, 140 mm tall, 152 mm deep — the S3 frame is a common footprint in Siemens SIRIUS lineups. That 20 mm forward clearance matters if you have a shallow enclosure depth. Power terminals accept stranded wire from 6 to 70 mm². Auxiliary and coil terminals take solid or stranded: 2x (0.5-1.5 mm²) or 2x (0.75-2.5 mm²). The coil connection uses screw-type terminals — no spring-cage here, so keep a screwdriver handy.
