Isolating switch 100A SV 4100 002423416

Isolator switch – safety and reliability in your installation

The SV 4100 isolator 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 works well as a main switch and as an individual installation element. The device does not have built-in overcurrent protection, so its only function is to isolate the circuit when maintenance or emergency work is required.

Construction features and application

The SV 4100 isolator switch is characterized by a solid construction and the possibility of sealing in the ON (on) and OFF (off) positions, which guarantees additional safety and prevents accidental switching on of the circuit during service work. The four-pole design makes it ideal for disconnecting three-phase loads. Mounting is done via a frame clamp, which facilitates the connection of wires with a cross-section from 2.5 mm² to 50 mm². Thanks to the IP20 protection class, the switch is resistant to touch and dust, ensuring safe operation.

Technical parameters and scope of application

The device is designed to operate at a maximum voltage of AC 400V and a rated continuous current of 100A. The rated conditional short-circuit current Iq is 4kA, which provides effective protection against the effects of short circuits. The SV 4100 isolator switch is used as:

• Main switch: in residential and industrial switchboards
• Safety switch: providing circuit isolation during service work
• Renovation switch: allowing safe disconnection of a fragment of the installation during modernization
• Emergency switch: allowing quick disconnection of power in hazardous situations

Thanks to its versatility and reliability, the SV 4100 isolator switch is an optimal solution for both professional installers and end-users looking for a safe and effective way to disconnect the electrical installation. The device's construction as a permanently mounted element ensures stability and long-term operation.
