Disconnect switch 40A SV 340 002423323

Isolator switch – safety and reliability in your installation

This three-pole SV 340 isolator switch with a rated current of 40A is a key element of any electrical installation, both in residential and industrial buildings. It serves as a reliable main switch or individual circuit breaker, providing effective isolation and safe operation. The device does not have built-in overcurrent protection, so its primary function is to disconnect the circuit in emergency situations or during maintenance work.

Functionality and application

The SV 340 isolator switch is designed for mounting on a TH rail, which facilitates its installation and integration with the existing distribution board. The ability to seal the lever in the ON (engaged) and OFF (disengaged) positions further increases safety, preventing accidental switching of the circuit on or off. This makes it ideal for applications requiring certainty and control over the circuit status. The possibility of mounting auxiliary contacts (PS ETIMAT 10) and overcurrent releases (DA ETIMAT 10) allows for expanding the functionality of the device and adapting it to specific installation needs.

Construction features and parameters

The construction of the isolator switch is based on solid materials and precise workmanship, which guarantees long-lasting and trouble-free operation. Frame clamps ensure a secure and durable connection of wires with a cross-section from 1 mm² to 25 mm². The device meets the standards PN-IEC 60947-3 and PN-EN 60947-3, which confirms its compliance with applicable safety standards. The protection degree IP20 protects against touching live parts. The rated conditional short-circuit current Iq is 2 kA, which provides protection against the effects of short circuits. The red lever facilitates visual identification of the switch status.

This switch is characterized by a rated current of 40 A and a rated AC voltage of 400 V. It has three poles and a rated conditional short-circuit current of 2 kA. The connection of the main contacts is realized by means of frame clamps, and the degree of protection is IP20. The device is intended for mounting on a TH rail, has a fixed construction and allows for sealing the lever in the ON/OFF positions.
