Siemens 3RT2015-1AF02 Power Contactor, 3-Pole, 7A, 110V AC Coil, 1NC Auxiliary Contact, Size S00

The Siemens 3RT2015-1AF02 is a robust 3-pole power contactor engineered for the precise and reliable switching of electrical loads in industrial environments. Designed with a compact S00 frame size, this device provides high performance while occupying minimal space in control cabinets. It operates with a 7A rated current and features a 110V AC control coil, making it a dependable component for various automation and motor control systems.

Advantages

This contactor offers exceptional durability and consistent performance even in demanding industrial conditions. Its compact design allows for efficient use of space in crowded electrical panels, while the integrated auxiliary contact simplifies circuit integration. The high-quality construction ensures long-term operational reliability, reducing the need for frequent maintenance and minimizing downtime in critical applications.

Suitable for

• Motor control and protection systems
• Industrial automation and process control
• Switching resistive and inductive loads
• HVAC system control panels

This contactor may not be suitable for applications requiring higher current ratings beyond its 7A capacity or for systems operating on DC control voltages, as this specific model is designed for 110V AC operation. It is also not intended for use in environments with extreme moisture or corrosive gases without appropriate protective enclosures.

Key specifications

• Number of poles: 3
• Rated operational current: 7A
• Control coil voltage: 110V AC
• Auxiliary contacts: 1 NC
• Size: S00

To use the Siemens 3RT2015-1AF02, mount the contactor onto a standard DIN rail or directly onto a mounting plate within your 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 to prevent overheating and ensure secure electrical contact.

What to consider before purchase

• Verify that your control circuit voltage matches the 110V AC coil requirement.
• Ensure the 7A current rating is sufficient for your specific load requirements.
• Check available space in your enclosure to confirm the S00 size fits your layout.
• Confirm the auxiliary contact configuration meets your feedback or interlocking needs.

Always ensure the power supply is disconnected before performing any installation or maintenance work on the contactor to prevent electrical shock. Regularly inspect terminal connections for tightness and signs of wear to maintain optimal performance.
