Disconnect switch 25A SV 425 002423422

Insulation disconnect switch – safety and reliability in your installation

This SV 425 insulation disconnect switch is a key element of any electrical installation, providing effective disconnection of the circuit in emergency situations or during maintenance work. Designed for use in both residential and industrial switchboards, it is a reliable solution for professionals and demanding users. Its robust construction and compliance with standards guarantee safe and long-lasting operation.

Functionality and application

The SV 425 insulation disconnect switch serves as a main or individual switch in electrical installations. It allows for safe disconnection of the circuit from the power supply, which is essential during servicing, repairs or modernization of the installation. The ability to seal the lever in the "On" and "Off" positions provides additional protection against accidental switching on or off. This ensures that the device meets work safety requirements and minimizes the risk of accidents.

It will find application in:

• Residential and industrial switchboards
• Individual electrical circuits requiring safe disconnection
• Installations powering devices with higher power consumption
• Modernization and renovation of electrical installations

Characteristics and benefits

The construction of the disconnect switch is based on a solid lever that enables quick and reliable switching of the circuit. Screw terminals provide easy and safe connection of wires with a cross-section from 1 mm² to 25 mm². The device has a protection class of IP20, which protects against accidental contact and prevents small solids from entering the interior.

Additional advantages:

• Versatility: Can function as a main, safety and renovation disconnect switch.
• Safety: The ability to seal the lever prevents accidental changes to the circuit state.
• Easy installation: Mounting on a TH35 rail ensures quick and easy installation.
• Durability: Made of high-quality materials guarantees long-term operation.
• Compatibility: The possibility of mounting an overcurrent release (optional) increases the functionality of the device.
• Contact position indicator: Allows for quick visual identification of the circuit status (on/off).

This disconnect switch is characterized by a rated current of 25A and a rated voltage of 400V AC, and its short-circuit breaking capacity is 2kA. The four-pole design allows for disconnection of all phases simultaneously, providing comprehensive protection of the electrical installation. The device meets the requirements of PN-IEC 60947-3 and PN-EN 60947-3 standards, which confirms its high quality and safety of use.
