Modular contactor SM 425 25A 230V 2NO 412523

Modular contactor for reliable circuit control

This compact modular contactor from Legrand, model SM 425, is an ideal solution for controlling various electrical circuits. Designed for easy mounting in modular installations, it provides reliable operation and safety. It is particularly useful in applications requiring frequent load switching, such as lighting, heating or motor control.

Construction and application

The SM 425 contactor is characterized by two normally open contacts (2NO), allowing control of two independent circuits. The rated operating current is 25A at 230V AC, making it suitable for protecting and controlling medium-power devices. Its width of only 1 module allows for efficient use of space in the distribution board. A manual control slider allows for manual switching of the contactor, which is useful for testing or maintaining the installation.

It will find application in:

• Lighting (controlling groups of lamps)
• Heating (controlling electric heaters)
• Home automation (controlling blinds, gates)
• Small industrial devices

Key features and benefits

• Compact dimensions: 1 module width makes it easy to install even in tight distribution boards.
• High switching capacity: Rated operating current of 25A allows safe control of devices with significant power. The maximum switching capacity for incandescent bulbs is as much as 3000W.
• Versatility: Two normally open contacts (2NO) increase application flexibility.
• Safety: IP2X protection degree provides basic protection against contact and ingress of solid objects. It has the CE marking confirming compliance with European standards.
• Expandability: Compatible with additional equipment, allowing you to adapt the functionality to individual needs.
• Convenient operation: Manual control slider facilitates testing and maintenance of the installation.
• Optimization of work with various types of loads: Maximum switching capacity for fluorescent lamps is 2100 VA, and for DUO-compensated fluorescent lamps – 2200 VA. For parallel-compensated fluorescent lamps, this value is 1000 VA.
