Modular network aggregation switch I-O-II 40A single-pole SSQ 140 002421415

Modular switch for reliable power switching

This 1-pole modular switch SSQ 140 with a rated current of 40A is a robust solution for switching between different power sources, especially in emergency situations such as power outages. Its design allows for mounting in standard distribution boards equipped with TH35 rails, which simplifies installation and integration with existing infrastructure. The switch is ideal for both professional installers and end-users looking for reliable power protection.

Functionality and application

The SSQ 140 switch enables simple and trouble-free switching between the mains and a generator. Three operating positions (I, 0, II) provide full control over the power source. The "0" position allows for complete disconnection of the load, which is useful during maintenance or repair. The ability to seal in the I or II position increases security and prevents unauthorized changes to the settings. This makes the device suitable for homes, workshops, production facilities and anywhere where uninterrupted power supply is required.

Design and characteristics

The switch has been designed with durability and ease of use in mind. It is made of high-quality materials, which guarantees long life and resistance to mechanical damage. 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. The IP20 degree of protection provides protection against touching fingers and against the ingress of solid objects larger than 12.5 mm. The distance between the contacts in the open state is greater than 3 mm, which meets the required safety standards (PN-IEC 60947-3). The device has a certificate from the DS Quality Research Office (BBJ), which confirms its compliance with the highest quality standards.
