Siemens 3RT2016-2JB42 SIRIUS Power Contactor, 9A, 4kW/400V, 24V DC Coil, 3-Pole, S00, Spring Terminal Original Brand New

Overview

The Siemens 3RT2016-2JB42 is a compact, high-performance SIRIUS 3RT20 power contactor designed for switching motors and electrical loads up to $9\text{ A}$ (AC-3e/AC-3) or $4\text{ kW}$ at $400\text{ V}$. This reliable 3-pole contactor features a $24\text{ V DC}$ control coil, making it perfectly suitable for direct connection to PLC outputs that require low-power switching. Its Size S00 frame ensures minimal space requirements in control cabinets.

A key feature is the integration of a suppressor diode directly into the coil circuit, which protects sensitive electronics like PLC outputs from switching surges. The spring-loaded terminals (also known as spring-type or spring clamp terminals) provide fast, vibration-proof, and maintenance-free wiring, significantly reducing installation time. It includes one integrated normally closed ($\text{1 NC}$) auxiliary contact.
