PV DC disconnect switch - 4-pole LS32 SMA A4+2 004660066

DC Photovoltaic Disconnector – Safety and Reliability in PV Systems

This 4-pole DC disconnector from ETI is a key element in photovoltaic installations, providing safe and effective disconnection of direct current circuits. Designed to work with DC/AC inverters and other components of PV systems, it guarantees reliable operation and minimizes energy losses. The disconnector design allows for quick and certain disconnection of the circuit, regardless of the operator's strength or speed – which is particularly important in emergency situations or during servicing of the installation.

Functionality and Application

The cam disconnector LS32 SMA A4 functions as a main, safety and maintenance disconnector. The possibility of mounting in distribution boards and its construction – a permanently fixed device – makes it a universal solution for both professional installers and end users. A rated continuous current of 58 A allows for use in higher power installations. Frame clamps facilitate cable connection, and a high degree of protection IP20 ensures safe use in various environmental conditions.
