DC-Switch Disconnectors for Photovoltaic

Product catalog summary

Overview: This document details the specifications and configurations for DC-Switch Disconnectors and Main Switches used in photovoltaic installations, adhering to IEC 60364-7-712 standards. These components are crucial for safely disconnecting DC/AC inverters from solar panels.

Specifications: The switch disconnectors are capable of handling up to 58A at 1000V in the DC21B category. They feature oxidation-proof contacts and support cable cross-sections up to 16mm². Available configurations include 2, 4, 6, and 8-pole options, with serial or parallel wiring to enhance contact ratings.

Product Variants: Various mounting options are available for both ON-OFF and Main Switches, such as panel mounting, single hole mounting, base mounting with door clutch, distribution boards, and plastic enclosures. Each variant is specified with its operational current and voltage ratings.

Technical Data: The switches are categorized under DC21B and DC22B, with detailed current ratings for different voltage levels (500V to 1000V). Wiring diagrams and switching examples are included to guide installation and operation.

Key Features: Designed for high reliability, the switches include features like oxidation-proof contacts and adjustable depths for certain models. They are equipped with IP66 or IP65 protection ratings, ensuring durability in various environmental conditions.

Ordering Information: Detailed ordering codes are provided for each switch type, along with packaging and weight information. Accessories such as extended switch shafts and padlock devices are mentioned for enhanced security.

Additional Specifications: The document outlines technical specifications for switch types LS16, LS25, and LS32, suitable for overvoltage categories I to III and pollution degrees 2 and 3, with an impulse withstand voltage (Uimp) of 8kV. Rated thermal current (Ithe) is 16A, 25A, and 32A respectively, with a rated insulation voltage of 1000V and 1500V.

Compliance and Standards: The switches comply with IEC 60947-3, VDE 0660, and GB14048.3 standards. Rated operational current (Ie) varies with voltage and configuration. Short-circuit and mechanical specifications include a rated conditional short-circuit current of 5 kAeff and mechanical life of 10,000 operations.

Cable and Terminal Specifications: Maximum cable cross-sections are provided for solid, stranded, and flexible cables. Terminal screws are M4 Pz2 with a tightening torque of 1.2 to 1.8 Nm.

Environmental Conditions: The maximum ambient temperature for operation is -40 to +65°C (open) and -40 to +45°C (enclosed). Storage temperature ranges from -50 to +90°C.

Power Loss: Power loss per switch at maximum Ie for DC21B is detailed for various configurations, with values ranging from 2W to 32W.

UL508 Compliance: The document includes data according to UL508 standards, with ampere ratings for general use at different voltages and configurations.

Approvals: The switches have approvals for use in the USA, Canada, Europe, and China, with UL and CCC certificates.

Dimensions: Dimensions for various configurations and mounting options are provided, including details for extended switch shafts and padlock devices.
