Siemens 3RT1016-1AP01 Contactor

Siemens 3RT1016-1AP01 Contactor is a compact three-pole power control device (size S00) with a 230 V AC coil designed for AC-3 duty. It features three normally open main contacts (3NO) and a single normally open auxiliary contact, all wired through screw terminals for straightforward installation. In the load circuit it is rated for up to 4 kW at 400 V and 9 A, making it suitable for switching small to medium three-phase motors, pumps, or conveyors in automation panels. The coil operates at 230 V AC with a 50/60 Hz supply, enabling reliable actuation from standard control voltages. This Siemens contactor is built for panel mounting and compatibility with existing 3RT1 accessories and auxiliary blocks, enabling simple expansion of control logic when needed. With the integrated auxiliary contact, you can implement feedback or interlock signals without adding a separate relay. The 3RT1016-1AP01's S00 footprint and screw-terminal construction support compact, durable installations in space-constrained enclosures and facilitate quick wiring in industrial control schemes. Whether used as a motor starter in a compact drive rack or as part of a PLC-controlled process line, this model delivers the essential combination of three-pole switching, a built-in auxiliary contact, and Siemens reliability in a small form factor.
