Modular contactor SM40A/4NO/3P, 40A, 4xNO (normally open) contacts, 230V coil, 2-module

NEO modular installation contactors are modern devices designed for remotely switching electrical circuits in low-voltage installations. They are an indispensable element of control systems, enabling safe and convenient management of higher-power loads, such as lighting, heating, ventilation, and industrial equipment. Their operation is based on an electromagnetic control mechanism – applying voltage to the contactor coil closes (or opens) the operating contacts, allowing for circuit control without the need for direct user intervention in the current path. This enables automatic or remote control of the installation, for example, using timers, sensors, or intelligent building systems. NEO modular contactors are available in several variants, differing in rated current, number of contacts (NO), and width expressed in the number of modules. Depending on the installation’s needs, they can handle both small loads (e.g., lighting circuits) and more demanding systems with high power consumption. The modular design allows for easy adaptation to the available space in the switchboard and the required functionality. Key advantages of NEO modular installation contactors: Remote control of circuits – they enable automatic switching of electrical devices on and off without user intervention. Wide range of applications – ideal for lighting, heating, ventilation, and other energy consumers. Variety of designs – available with different rated currents, contact counts, and widths (1–3 modules), allowing you to select the right device for your specific application. Compact modular design – mounts on a standard TH35/DIN rail, easily integrates with modular equipment in distribution boards. Reliability and durability – designed for frequent switching cycles and long-term operation in electrical installations. Quiet and safe operation – suitable for use in residential and public buildings. Thanks to their functionality and flexible configuration, NEO installation contactors are a key element of modern electrical installations, providing convenient control, optimizing the operation of consumers, and increasing comfort and energy efficiency.
