Isolator switch 125A SV 1125 002423117

Insulation disconnect switch – safety and reliability in your installation

This SV 1125 insulation disconnect switch is a key element of any electrical installation, providing safe and controlled disconnection of circuits. Designed for use in both residential and industrial switchboards, it is a reliable solution for professionals and demanding users. Its solid construction and high-quality workmanship guarantee long-lasting and trouble-free operation.

Functionality and application

The SV 1125 switch serves as a main switch in switchboards and as an individual isolator in electrical installations. It does not have built-in overcurrent protection, which means its main function is to isolate the circuit – safely disconnect the power to perform maintenance or repair work. The ability to seal the lever in the "On" and "Off" positions further increases safety, preventing accidental switching on or off of the circuit. This makes it ideal for applications where certainty of circuit status is required.

Key features and benefits

• Rated current 125A: Allows safe disconnection of circuits with high current draw, which is particularly important in industrial installations and workshops.
• Rated continuous current (Iu) 125A: Guarantees stable operation of the device under prolonged load.
• Rated conditional short-circuit current (Iq) 4kA: Provides resistance to the effects of short circuits, protecting the installation from damage.
• Device construction: Fixed mounting ensures stability and reliability of the connection.
• Protection degree IP20: Protection against contact with fingers and against the ingress of solid objects larger than 12.5 mm – standard protection for devices mounted inside enclosures.
• Main contact connection type - Frame terminal: Allows easy and quick connection of wires with a cross-section of up to 50 mm².
• Possibility of mounting on TH rail: Standard mounting on TH35 rail facilitates integration with existing switchboards.
• Contact position indicator: Allows unambiguous determination of the switch status (on/off).
• Maximum rated operating voltage AC 230V: Suitable for standard electrical networks.

This disconnect switch is not only a technical element, but above all an investment in the safety of your electrical installation and peace of mind during use. Solid workmanship and compliance with PN-IEC 60947-3 and PN-EN 60947-3 standards confirm its high quality and reliability.
