Modular contactor SM 425 25A 230V 4NO with actuator 412551

Modular contactor for a wide range of applications

The SM 425 25A 230V modular contactor with four normally open contacts (4NO) is a reliable solution for controlling various electrical loads. It is suitable for both home installations and commercial or industrial facilities. Its compact size – only two modules wide – makes it easy to mount in distribution boards. An additional actuator allows manual control of the contactor, which is useful during testing, maintenance or failures.

Functionality and technical parameters

The device is designed to operate with a control voltage AC in the range of 195-253V and a working voltage of 400V. The rated current of the contactor is 25A, which allows it to handle loads with a power of up to 3000W for incandescent bulbs and 2100VA for fluorescent lamps. Thanks to the possibility of additional equipment, e.g. an auxiliary contact, the functionality of the device can be expanded and adapted to the specific needs of the installation. The contactor has a protection class of IP2X, which provides basic protection against touching and the ingress of solid objects.

• Versatility: Four normally open contacts (4NO) allow control of various loads.
• Compact size: 2 module width makes it easy to install in tight spaces.
• Actuator: Allows manual control of the contactor, useful for service and testing.
• Protection: Rated operating current of 25A ensures safe operation.
• Flexibility: Possibility of expansion with additional equipment, e.g. auxiliary contacts.
• Application: Ideal for controlling lighting, heating, pumps and other electrical devices.

Installation and compliance with standards

The installation of the contactor is simple and intuitive thanks to the standard module dimensions. The device meets applicable safety standards, which guarantees its reliable operation and long life. Made of high-quality materials, it ensures durability even in harsh operating conditions. The mounting depth is 44 mm, which should be taken into account when planning the installation.
