Modular contactor SM 425 25A 24V 4NO with actuator 412517

Modular contactor – reliable control of electrical circuits

This 4-pole modular contactor with a rated current of 25A and a control voltage of 24V AC is a key element in electrical installations, providing safe and efficient circuit switching. Equipped with a manual operator, it enables convenient manual operation, which is particularly useful during testing and maintenance. The 2-module design allows for easy mounting in switchboards, saving valuable space.

Functionality and application

This contactor is used in a wide range of electrical installations, both in residential and commercial buildings. It is ideal for controlling lighting, heating, ventilation and other electrical devices. Thanks to four normally open contacts (4NO), it allows simultaneous switching of several circuits. The rated operating voltage of 400…400V ensures compatibility with most standard installations.

• Versatility: Can be used in various types of circuits – lighting, heating, ventilation.
• Easy installation: 2 module width makes installation in switchboards easier.
• Convenient operation: Operator allows manual control of the contactor.
• Compatibility: Compliance with IEC/EN 61095 standard guarantees safety and reliability.
• Integrated system: Compatible with the Legrand EMS CX3 energy management system, which allows for optimization of energy consumption and monitoring of installation parameters.

Technical parameters and construction

The contactor is designed for durability and reliability. The IP2X degree of protection protects against touching live parts and the ingress of solid objects larger than 12.5 mm. Made of high-quality materials, it ensures a long service life even in harsh working conditions. The rated operating current is 25A, and the maximum switching capacity for incandescent lamps is as much as 3000W. The type of control and supply voltage is AC (alternating current). Additional options increase the functionality of the device – e.g. auxiliary contacts or surge protectors can be connected to it. C characteristic makes the contactor cope well with starting devices with a motor – allows short-term overloads without unnecessary tripping.
