Siemens SIRIUS 3RT2025-2NP30 Power Contactor, 17A, 7.5kW, 3-Pole, 200-280V AC/DC Coil, Size S0, Spring-Loaded Terminal Original Brand New

Overview

The Siemens 3RT2025-2NP30 Power Contactor from the trusted SIRIUS 3RT2 series is a high-performance, compact switching device engineered for controlling motors and industrial electrical circuits. Rated for 17 A (AC-3e/AC-3) and 7.5 kW at 400 V, this 3-pole contactor is a reliable core component in motor control applications up to $250\text{ kW}$ (as part of the $3\text{RT}$ family).

It features a wide-range 200-280 V AC/DC control voltage with an integrated varistor for surge suppression, ensuring robust and reliable operation across varying supply conditions. The inclusion of spring-loaded terminals allows for quick, vibration-proof, and maintenance-free wiring, significantly reducing installation time.

Benefit

1. High Reliability & Protection: The integrated varistor provides essential coil protection against voltage surges, extending the contactor’s lifespan and ensuring greater operational reliability.
2. Fast & Secure Wiring: The innovative spring-loaded terminal technology enables tool-free, rapid connection of conductors, offering a high-contact pressure connection that is resistant to vibration and eliminates the need for periodic re-tightening.
3. Space-Saving Design: Its compact Size S0 form factor allows for high packing density in control cabinets, optimizing panel space and overall system footprint.
4. Flexible Control: The wide-range $\text{AC/DC}$ control voltage ($200-280\text{ V}$) simplifies procurement and engineering by covering multiple common supply voltages with a single product.
5. Standardized Integration: As part of the SIRIUS modular system, the $3\text{RT}2$ is easily combinable with other SIRIUS components like overload relays and circuit breakers.

Function

The 3RT2025-2NP30 functions as an electromechanical switch used to control a motor or other high-power electrical loads. When the $200-280\text{ V AC/DC}$ control voltage is applied to the coil, it magnetically closes the three main power contacts, connecting the $400\text{ V},7.5\text{ kW}$ load to the power source.

The integrated $1\text{ NO}+1\text{ NC}$ auxiliary contacts provide status feedback and interlocks for control circuitry. It is specifically designed for switching 3-phase $\text{AC}$ loads, typically in $\text{AC-3}$ (motor starting/running) and $\text{AC-3e}$ (enhanced efficiency motor switching) duty cycles.
