Installation modular contactor 25A, 3xNO + 1xNC, 24V AC/DC STM-25-31/24V EXT10000293

Modular contactor for lighting and heating control

This ZAMEL brand modular installation contactor is a reliable solution for controlling electrical circuits in residential and commercial buildings. Designed for convenient installation and aesthetic appearance, it is ideal for installations where both functionality and a neat look are important. The device is particularly useful in lighting, heating and simple automation control systems.

Construction and application

The STM-25-31/24V contactor is characterized by a universal contact arrangement of 3xNO (normally open) + 1xNC (normally closed). This allows for flexible adaptation to different control schemes. The device coil is designed to operate with 24V AC/DC voltage, ensuring compatibility with a wide range of control systems. The maximum current of 25A in AC5b and AC7a categories guarantees safe and efficient operation even with higher loads. The ability to cooperate with auxiliary contacts SPM-05-11 and SPM-05-20 expands the functionality of the contactor, enabling the implementation of more advanced applications.

Key advantages and benefits

• Versatility: 3xNO+1xNC contact arrangement allows for use in various control circuits.
• Compatibility: 24V AC/DC coil ensures cooperation with popular control systems.
• High efficiency: Rated current of 25A (AC5b, AC7a) enables control of larger loads.
• Easy installation: Modular design simplifies installation on a TH35 rail.
• Expandability: Possibility of cooperation with auxiliary contacts SPM-05-11 and SPM-05-20 increases the functionality of the device.
• Safety: Provides effective protection of the circuit against overload and short circuit - like most circuit breakers in this class.
• Aesthetics: Aesthetic housing improves the appearance of the electrical installation.

Thanks to these features, the STM-25-31/24V contactor is an optimal choice for both professional installers and end users looking for a reliable and easy-to-use solution for controlling electrical circuits.
