Furthermore, the device is built to withstand the demands of frequent switching operations, offering consistent performance in lighting, heating, and ventilation control applications.

Suitable for

• Controlling residential and commercial lighting systems
• Managing electric heating circuits
• Operating ventilation and air conditioning units
• Automated switching in electrical distribution boards

This device may not be suitable for high-power industrial motor starting applications or circuits that exceed the rated current of 25A. It is also not intended for use in environments with extreme moisture or corrosive atmospheres without appropriate protective enclosures.

Key specifications

• Rated current: 25A
• Configuration: 1-pole
• Contact arrangement: 1NO + 1NC
• Mounting type: DIN rail
• Application: Modular electrical switching

To use the Bemko SC101, ensure the power supply is disconnected before installation. Mount the contactor onto a standard 35mm DIN rail within a suitable distribution board. Connect the control circuit wires to the coil terminals and the load circuit wires to the power terminals according to the wiring diagram provided on the device housing. Once installed, verify all connections for tightness and ensure the device operates correctly before restoring power to the system.

What to consider before purchase

• Verify that the 25A current rating is sufficient for your specific load
• Ensure the 1NO+1NC contact configuration meets your control logic requirements
• Confirm that there is available space on your DIN rail
• Check that the operating voltage of your control circuit matches the device specifications

Usage recommendations

For optimal longevity and safety, ensure the contactor is installed in a well-ventilated enclosure and periodically inspect the terminal connections for tightness to prevent overheating.
