It supports both PROFINET and PROFIBUS DP protocols, allowing direct integration into either network without a separate gateway. Rated for 24 V DC control supply with a permissible range of 20.4 to 28.8 V, the module provides 2 digital inputs and 2 bytes each of input and output process data. The adjustable trip class — CLASS 10 and 10A — lets you match the thermal overload characteristic to the motor start profile, critical for high-inertia loads or frequent starting duty. Short-circuit breaking capacity is 50 kA at 400 V, certified per IEC 60947-4-1. This SCCR rating means the starter can clear a fault up to 50 kA without upstream protective device intervention, simplifying coordination in high-fault panels. ## Physical integration and environmental limits Dimensions are 150 mm depth, 65 mm width, and 290 mm height. The module mounts by plugging onto a terminal module, not direct DIN-rail snap-on — the base terminal module carries the power and bus connections, and the starter unit mates onto it. This split design means you can pre-wire the terminal module and swap the electronics without touching the field wiring. Vibration resistance is 2g, shock resistance is 5g for 11 ms. Pollution degree is rated 3 at 400 V and 2 at 500 V per IEC 60664 and IEC 61131 — this matters for panels in dusty or conductive-contaminant environments where creepage distances must be maintained. Mounting position is vertical or horizontal, giving flexibility in tight enclosures. The main energy infeed uses screw-type terminals on the base module; energy transmission between modules is via an internal energy bus, reducing point-to-point wiring for multi-starter groups. Sourcing is quoted to order against the BOM quantity. The module is not held in ready inventory at this storefront; each RFQ is processed against live distributor stock and manufacturer lead times.","metaTitle":"Siemens 3RK1301-0AB20-0AA4 SIMATIC Motor
