Modular network aggregation switch I-O-II 25A 2-pole SSQ 225 002421424

Mains-Generator Modular Switch – Reliable Power Source Switching

This 2-pole modular switch SSQ 225 with a rated current of 25A is a key element of electrical installations, providing smooth and safe switching between different power sources. It is ideal for emergency situations, such as a mains power failure, allowing automatic switching to backup power. Mounting is on a TH35 rail, which facilitates integration with the existing distribution board.

Functionality and application

The SSQ 225 switch is designed to operate in mains-generator (I-0-II) systems, where the "0" position allows for complete disconnection of the load. This solution is particularly useful in applications requiring complete isolation from both power sources during servicing or maintenance. The ability to seal in the I or II position further increases safety and prevents unauthorized changes to the settings. This ensures stable and reliable system operation for both installers and end users.

Construction and characteristic features

Made of high-quality materials, the SSQ 225 switch is characterized by durability and resistance to environmental conditions. The connection terminals allow connection of stranded wires with a cross-section of 1.5 - 10 mm² and solid wires with a cross-section of 1.5 - 16 mm². It meets the PN-IEC 60947-3 standard, which confirms its compliance with European safety standards. The distance between contacts in the open state is greater than 3mm, providing additional safety during maintenance work. The degree of protection is IP20, protecting against accidental contact. The product has a certificate from the DS Quality Research Office (BBJ).
