Isolating switch 125A SV 2125 002423217

Insulating disconnect switch SV 2125 is a reliable and proven solution for connecting and disconnecting electrical circuits. Designed for use as a main switch in residential and industrial switchboards, as well as an individual switch in electrical installations. The device is characterized by a solid construction and the possibility of sealing in the on or off position, which provides additional safety.

Functionality and application

This two-pole switch with a rated current of 125A is perfect for installations with an AC voltage of up to 400V. Its construction, based on permanent mounting on a TH rail, guarantees stability and ease of installation. The possibility of connecting cables with a cross-section from 2.5 mm² to 50 mm² provides flexibility when choosing the appropriate cables. It meets the requirements of PN-IEC 60947-3 and PN-EN 60947-3 standards, which confirms its compliance with applicable safety standards.

Construction and characteristic features

The SV 2125 disconnect switch is distinguished by its intuitive operation thanks to the red lever, which makes it easier to quickly identify the device's status. It has a contact position indicator, which allows for unambiguous determination of whether the circuit is on or off. The possibility of double connection of the insulating busbar (top and bottom) increases the convenience of mounting and adaptation to different installation configurations. In addition, the device has a protection class of IP20, which provides protection against accidental contact. The use of high-quality materials guarantees long-term and trouble-free operation in the range of ambient temperatures from -25°C to 70°C.

• A rated current of 125A ensures safe operation of circuits with a high load.
• Two-pole construction allows disconnecting both the phase and neutral conductor simultaneously.
• Rated conditional short-circuit current of 4 kA increases resistance to the effects of short circuits in the installation.
• The possibility of sealing prevents unauthorized switching on or off of the device.
• Mounting on a TH rail ensures quick and easy mounting in the switchboard.
• Wide range of cable connection guarantees compatibility with different types of cables.
• Contact position indicator facilitates intuitive operation and control of the device status.
• Possibility of use as an emergency switch, main switch, safety switch and maintenance switch expands the scope of application of the device in various emergency situations or during maintenance work.
