Disconnect switch 25A SV 125 002423122

Isolator – safety and reliability in your installation

This SV 125 isolator is a key element of any electrical installation, providing safe and effective disconnection of circuits. Designed for use in both residential and industrial applications, it offers reliable operation and easy installation. Its robust construction and compliance with standards guarantee long-term operation.

Functionality and application

The SV 125 isolator serves as a main switch in distribution boards and as an individual switch in electrical installations. It does not have built-in overcurrent protection, which means its main function is to isolate the circuit. The ability to seal the lever in the ON or OFF position increases safety and prevents accidental switching of the circuit. This makes it ideal for applications where certainty of circuit status is required – e.g. during maintenance or repair.

• Versatile application: ideal for residential and industrial distribution boards, as well as an individual switch.
• Safety: the ability to seal the lever provides protection against unauthorized access and accidental change of circuit status.
• Easy installation: designed for mounting on TH35 rail, which simplifies and speeds up installation.
• Durability: robust construction guarantees long-lasting and trouble-free operation.
• Compliance with standards: meets the requirements of PN-IEC 60947-3 and PN-EN 60947-3, confirming its safety and quality.

Technical parameters and construction

The SV 125 isolator is characterized by a rated current of 25A and a rated voltage of AC 230V. Its single-pole construction makes it ideal for simple circuits. Connection of the main contacts is made using frame clamps, which ensures a secure and durable connection of wires with a cross-section from 1 mm² to 25 mm². The IP20 degree of protection protects against finger contact and the ingress of solid objects larger than 12.5 mm. The device is designed as a permanently mounted element, which ensures stability and reliability of operation. Additionally, the isolator has an optional possibility of mounting an overcurrent release (DA ETIMAT 10), which allows it to be adapted to specific installation needs. The rated conditional short-circuit current Iq is 2kA.
