Siemens 3RT2026-1AF00 Power Contactor, 3-Pole, 25A, 110V AC Coil, Size S0

The Siemens 3RT2026-1AF00 is a robust 3-pole power contactor engineered for the reliable switching of electrical loads in industrial settings. Built to size S0 standards, this device offers a rated operational current of 25A and is equipped with a 110V AC control coil. It is designed to provide consistent performance and longevity, making it a dependable component for complex electrical systems and automation infrastructure.

Advantages

This power contactor stands out due to its compact S0 design, which saves valuable space in control cabinets without compromising on power capacity. The inclusion of integrated auxiliary contacts, specifically one normally open and one normally closed contact, allows for seamless integration into various control and monitoring circuits. Its high-quality construction ensures resistance to mechanical and electrical wear, facilitating long-term operational reliability in demanding industrial environments.

Suitable for

• Industrial motor control systems
• Automation and process control applications
• Switching resistive and inductive electrical loads
• Integration into complex control panels

This contactor may not be suitable for applications requiring a DC control voltage, as this specific model is designed exclusively for a 110V AC coil. Additionally, it is not intended for use in environments exceeding its specified current rating of 25A or in conditions where extreme environmental hazards, such as high moisture or corrosive gases, are present without appropriate protective enclosures.

Key specifications

• Number of poles: 3
• Rated operational current: 25A
• Control coil voltage: 110V AC
• Size: S0
• Auxiliary contacts: 1NO + 1NC

To use the Siemens power contactor, mount the device onto a standard DIN rail or a flat surface within a control cabinet. Connect the main power lines to the primary terminals and wire the 110V AC control signal to the coil terminals. Ensure that all connections are tightened to the manufacturer's specified torque settings to prevent overheating. Integrate the auxiliary contacts into your control logic as required for your specific application.

What to consider before purchase

• Verify that your control circuit provides a 110V AC signal.
• Ensure the 25A current rating is sufficient for your connected load.
• Check available space in your enclosure for size S0 components.
• Confirm the auxiliary contact configuration meets your control requirements.

For optimal performance and safety, always ensure that the contactor is installed by a qualified professional and that the electrical circuit is properly fused according to local regulations. Regularly inspect the terminals for tightness and check for signs of wear during routine maintenance intervals.
