Installation modular contactor 25A, 3xNO, 230V AC STM-25-30 EXT10000291

Modular contactor for controlling electrical circuits

This modular contactor, designed for mounting on a TH35 rail, is a reliable solution for controlling lighting, heating, and simple automation systems. Its design ensures convenient installation and an aesthetic appearance in electrical installations. The device is characterized by high efficiency and durability, making it an ideal choice for both professional installers and end users.

Functionality and application

The STM-25-30 contactor is equipped with three normally open contacts (3xNO), allowing simultaneous switching of multiple circuits. A maximum current of 25A in AC5b and AC7a categories guarantees safe and efficient operation with various types of loads. The ability to cooperate with auxiliary contacts SPM-05-11 and SPM-05-20 expands the functionality of the device, enabling the implementation of more complex control systems.

• Versatile application: ideal for controlling lighting, heating, ventilation, and simple home and industrial automation systems.
• Safety: provides reliable switching of electrical circuits, protecting devices from overload.
• Compatibility: possibility of expanding the system through cooperation with auxiliary contacts SPM-05-11 and SPM-05-20.
• Convenient installation: modular design simplifies installation on a TH35 rail, saving time and minimizing costs.
• Durability: made of high-quality materials, guaranteeing long-lasting and trouble-free operation.

Technical characteristics and construction

The STM-25-30 contactor has been designed with demanding installation applications in mind. Its solid construction and precise workmanship ensure reliable operation even in difficult conditions. The 3xNO contact arrangement allows flexible configuration of control circuits, and the rated current of 25A allows handling a wide range of loads. It is important to remember its intended use for AC5b and AC7a categories – this means it copes well with inductive loads, such as motors or transformers. Therefore, it can be safely used in systems with devices requiring higher starting current.
