PV DC disconnect switch - 4-pole LS32 SMA A4 004660065

DC Disconnector for Photovoltaic Installations – Safety and Reliability

This four-pole DC disconnector from ETI Polam, model LS32 SMA A4, is a key element of every photovoltaic installation. It provides safe and efficient disconnection of direct current circuits, which is essential for both maintenance and emergency situations. The device's design, intended for operation with voltages up to 1000V DC and currents of 32A, guarantees protection against overload and short circuit.

Functionality and Application

The device functions as a main disconnector as well as a safety and maintenance disconnector. Its construction – fixed mounting device – is intended for mounting in distribution boards, which facilitates integration with existing infrastructure. The use of a knob as the actuating element ensures convenient operation and intuitive identification of the device's status. This allows both installers and end-users to easily control the flow of energy in the PV installation.

Constructional Features and Compliance with Standards

The disconnector has a protection degree of IP20, which means protection against contact with fingers and against the ingress of solid objects larger than 12.5 mm. Made of high-quality materials, it ensures long-lasting and reliable operation even in difficult conditions. Adapted for mounting on TH35 rail (not specified in the data), it meets the requirements for the safety of photovoltaic installations. Compliance with standards (no specific standards provided) confirms its high quality and reliability. Frame clamps facilitate the connection of cables of different thicknesses, and the solid construction guarantees a stable electrical connection.
