Product information

Description

The Siemens SIRIUS 3RT2025-1BB40 is a robust 3-pole power contactor engineered for demanding industrial switching environments. Designed to handle a rated operational current of 17A, this device ensures reliable performance in motor control and power distribution systems. It operates with a 24V DC control supply voltage, making it a versatile component for modern automation panels and electrical infrastructure.

Advantages

This contactor stands out due to its compact S0 size, which allows for efficient space utilization within control cabinets without compromising on power capacity. The integrated auxiliary contact configuration, consisting of one normally open and one normally closed contact, provides essential feedback and interlocking capabilities for complex control circuits. Its durable construction ensures long-term operational stability even in high-frequency switching applications, reducing maintenance requirements and downtime.

Suitable for

Industrial motor control systems
Automation and control panels
Heating and lighting circuit switching
Electrical distribution infrastructure

When it may not be suitable

This device is not intended for applications requiring AC control voltages, as it is specifically designed for 24V DC operation. It may also be unsuitable for environments exceeding its rated operational current of 17A or for installations where the physical dimensions of the S0 frame size do not fit the existing mounting layout.

Key specifications

Rated operational current: 17A
Number of poles: 3
Control supply voltage: 24V DC
Auxiliary contacts: 1 NO + 1 NC
Frame size: S0

How to use

Installation should be performed by qualified personnel in accordance with local electrical regulations. The contactor is designed for mounting on standard DIN rails or via screw fixing within an enclosure. Connect the main power lines to the primary terminals and the 24V DC control signal to the coil terminals. Ensure that all connections are tightened to the specified torque to prevent overheating and ensure secure electrical contact.

What to consider before purchase

Verify that your control system provides a 24V DC supply.
Check that the 17A current rating is sufficient for your specific load requirements.
Ensure the S0 frame size is compatible with your current panel layout.
Confirm the auxiliary contact configuration meets your interlocking or signaling needs.

Usage recommendations

Regularly inspect the terminal connections for tightness and check for any signs of wear or debris accumulation to maintain optimal performance and safety standards throughout the service life of the contactor.
