SWITCH DISCONNECTOR

Product catalog summary

Overview: The document provides technical specifications and details for DC-Switch Disconnectors used in photovoltaic installations, compliant with IEC 60364-7-712 standards. These disconnectors are essential for safely interrupting the connection between DC/AC inverters and solar panels.

Specifications:

Rated Operational Voltage: 1000V DC
Rated Operational Current: Up to 32A
Poles: Available in 2, 3, or 4-pole configurations
Contact Material: Oxidation-proof to prevent inadmissible heating
Cable Cross Sections: Supports up to 16mm²

Switching Programs: The document outlines various configurations for switch disconnectors, including 2-pole, 2+2-pole, and 4-pole setups. These configurations allow for series and parallel wiring to enhance contact ratings.

Technical Data: The document provides detailed technical data for different types of switch disconnectors (LS16, LS25, LS32) under various voltage conditions (500V, 600V, 800V, 1000V) and load categories (DC21B, DC22B). It specifies the current ratings for each configuration and load type.

Design and Ordering: The document includes information on ordering switch types, designations for main switches and emergency stops, and switching programs. It also provides details on the number of poles and specific configurations.

Dimensions: Dimensions for various models (LS16, LS25, LS32) are provided, including mounting hole specifications and optional padlock devices for security.

Key Features:

Reliable switching up to 32A with 1000V in DC21B category
Manual operation with consistent switching performance
Prevention of oxidation and overheating
