Installation modular contactor 25A, 1xNO + 1xNC, 230V AC STM-25-11 EXT10000290

Modular contactor for lighting and heating control

This modular contactor, designed for mounting on a TH35 rail, is a reliable solution for controlling electrical circuits in domestic and industrial installations. Designed to operate at 230V AC, it enables safe and efficient management of larger loads using low-voltage control signals. The device finds application in building automation, heating systems, lighting, and simple control systems.

Construction and functionality

The STM-25-11 contactor is characterized by its compact design and ease of installation. It has a contact arrangement of 1xNO (normally open) and 1xNC (normally closed), providing flexibility in circuit configuration. The rated current of 25A in AC5b and AC7a categories guarantees the ability to handle various loads. Additionally, the contactor is compatible with auxiliary contacts SPM-05-11 and SPM-05-20, allowing for expansion of the control system functionality. A built-in LED indicator signals the device's on status, facilitating diagnostics and monitoring of operation.

Application and benefits

• Versatility: Ideal for controlling lighting, heating, ventilation and other electrical devices.
• Safety: Provides galvanic isolation between the control circuit and the load, minimizing the risk of damage and providing protection against short circuits and overloads.
• Easy installation: Modular design allows for quick and convenient mounting on a standard TH35 rail.
• Compatibility with accessories: Compatibility with auxiliary contacts SPM-05-11 and SPM-05-20 expands the possibilities of using the contactor in more complex automation systems.
• Durability: Made of high-quality materials, ensuring long life and reliable operation even in harsh operating conditions.
• Quiet operation: Minimal noise level during operation ensures user comfort.

Remember to take appropriate safety precautions during installation and operation of the device – SEP 1kV qualifications are recommended and the power supply should be disconnected before starting installation work.
