Isolating switch 125A SV 4125 002423417

Reliable isolating switch for domestic and industrial installations

The SV 4125 isolating switch is a key element of any electrical installation, providing safe and reliable disconnection of the circuit. Designed for both residential and industrial switchboards, it also works well as an individual switch in more complex electrical systems. The device allows for safe disconnection of the power supply for maintenance or repair work.

The switch's construction is based on solid materials and precise workmanship, guaranteeing long-lasting and trouble-free operation. 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 an ideal solution for places requiring enhanced safety standards.

Functionality and technical parameters

The SV 4125 switch is characterized by a rated current of 125A and a rated voltage of 400V AC, making it suitable for use in circuits with medium and high power. The four-pole design provides complete circuit isolation, and the compact dimensions (4 modules) allow for easy mounting on a TH rail. The frame terminals facilitate the connection of wires with a cross-section from 2.5 mm² to 50 mm², ensuring a solid electrical connection. The IP20 degree of protection protects against accidental contact and the ingress of small solid objects.

It is worth noting the possibility of mounting auxiliary contacts (PS ETIMAT 10) and overcurrent releases (DA ETIMAT 10) – this option allows you to expand the functionality of the device and adapt it to the specific needs of the installation. The contact position indicator facilitates visual control of the device status, and the red lever intuitively indicates the on/off status.

Application and compliance with standards

The SV 4125 isolating switch finds wide application as:

• Main switch in residential and industrial switchboards – provides a central point for disconnecting the power supply to the entire installation.
• Individual switch in electrical installations – allows disconnection of individual circuits for service or repair work.
• Safety switch – provides quick and safe disconnection of the power supply in emergency situations.
• Repair switch – allows safe disconnection of the power supply during renovation or modernization work.

The device meets the requirements of PN-IEC 60947-3 and PN-EN 60947-3 standards, confirming its high quality and safety of use.
