Siemens 3RT2027-1FB40 Power Contactor, 32A, 15kW, 24V DC, 1NO+1NC, S0 Original Brand New

Overview: Siemens 3RT2027-1FB40 SIRIUS Power Contactor

The Siemens 3RT2027-1FB40 is a high-performance, 3-pole power contactor from the trusted SIRIUS 3RT2 series, specifically engineered for switching electric motors and other demanding loads up to 32A (AC-3e/AC-3 rating). Designed in a compact Size S0 for space-saving integration, this contactor offers exceptional reliability and is integral to modern industrial automation and motor control applications.

It is rated for a power output of 15 kW at 400 V and features a low-power, energy-efficient 24 V DC control voltage. The integrated plugged-in diode combination provides surge suppression, ensuring coil longevity and protection of connected control circuits.

Function & Application

The 3RT2027-1FB40 functions as the primary switching element in load feeders, enabling the remote and automatic connection and disconnection of loads. Its robust design is primarily intended for:

• Motor Control: Direct-on-Line (DOL) starting and switching of 3-phase motors (up to 15 kW).
• Industrial Automation: Switching heaters, lighting systems, and other high-current resistive or inductive loads.
• Safety Circuits: Used in conjunction with other SIRIUS components to build approved safety load feeders.

Benefit

• High Reliability: Part of the modular Siemens SIRIUS system, ensuring coordinated, tested performance.
• Space Saving: Compact S0 frame size minimizes panel footprint.
• DC Coil Efficiency: The 24V DC coil with integrated diode reduces power consumption and simplifies wiring with common control voltages.
• Ease of Wiring: Standardized screw terminals allow for simple, secure, and familiar installation.
• Global Compliance: IE3/IE4-ready and approved for worldwide use (IEC, UL/CSA, etc.).
