This modular contactor stands out due to its high build quality and operational reliability, which are hallmarks of Siemens engineering. The device is designed to handle frequent switching operations without compromising safety or performance. Its 24V AC control voltage makes it compatible with a wide range of automation and control systems, while the four normally open contacts offer flexibility for managing multiple load circuits simultaneously. The unit is built to withstand the rigors of continuous use, providing a durable solution for modern electrical installations.

Suitable for

• Residential lighting control systems
• Industrial heating and ventilation equipment
• Automation of electrical distribution circuits
• Switching of single-phase and three-phase loads

When it may not be suitable

This contactor is not designed for applications requiring a control voltage other than 24V AC. It is also not intended for use in environments with extreme moisture or corrosive gases unless housed in an appropriate protective enclosure.

Key specifications

• Rated current: 25A
• Contact configuration: 4 normally open (NO)
• Control voltage: 24V AC
• Mounting type: DIN rail
• Weight: 0.259 kg

How to use

The device is designed for installation on a standard DIN rail within a distribution board. Ensure that the power supply is disconnected before beginning the installation. Connect the control circuit wires to the designated coil terminals and the load circuit wires to the main power terminals. Verify that all connections are tightened securely according to the specified torque requirements to prevent overheating. Once installed, the contactor will automatically switch the connected loads when the 24V AC control signal is applied.

What to consider before purchase

• Verify that your control system provides a 24V AC signal.
• Ensure the 25A current rating is sufficient for your specific load requirements.
• Check the available space in your distribution board for DIN rail mounting.
• Confirm that the four normally open contacts meet your circuit switching needs.

Usage recommendations

Regularly inspect the contactor for any signs of wear or loose connections during routine maintenance of your electrical panel. Ensure that the ambient temperature around the device remains within the manufacturer's specified operating range to maintain optimal performance and longevity.
