Fire disconnect switch SOL30-SAFETY for 4 PV strings, MC4, 230VAC SOL30X4-SAFETY-MC4-U(230V50HZ) 168102

DC Disconnector for Photovoltaic Installations

This SOL30-SAFETY DC disconnector is designed for safely disconnecting DC circuits in photovoltaic installations. It provides effective protection against the effects of short circuits and overloads, and also allows for safe maintenance work. The design with four MC4 inputs allows connection to four strings of photovoltaic panels, making it an ideal solution for larger installations.

Features and Application

The device has been designed with ease of installation and use in mind. The housing made of plastic provides high resistance to weather conditions (IP65), allowing installation both indoors and outdoors. The switch with a knob allows for quick and reliable disconnection of the circuit, and the presence of auxiliary contacts (1 normally closed, 1 normally open) enables integration with monitoring and control systems. The disconnector meets the IEC/EN 60 947-3 standard, which guarantees its safety and reliability.

• PV installation protection: Protects against the effects of short circuits and overloads in DC circuits.
• Easy installation: Can be mounted on a plate, making it easy to integrate with existing infrastructure.
• Weather resistance: IP65 protection rating ensures reliable operation in harsh outdoor conditions.
• Multistring capability: Supports up to four strings of photovoltaic panels (MC4).
• Status signaling: The presence of auxiliary contacts enables remote monitoring of the disconnector status.
• Safety: Compliance with IEC/EN 60 947-3 confirms a high level of safety.
• Durability: Made of high-quality materials, ensuring long-term operation.

User parameters and construction

The SOL30-SAFETY disconnector is characterized by a rated current of 30A and a working voltage of up to 1000V DC. The device construction includes a complete unit in a housing, eliminating the need for additional mounting elements. The return mechanism to the "0" position provides additional safety during maintenance and repairs. The red color of the control element makes it easier to identify the disconnector in the event of a failure or the need for a quick disconnection of the circuit. The use of a screw connection for the main contacts guarantees a secure and durable electrical connection. Additionally, the device has a locking mechanism to prevent accidental switching on after an emergency shutdown.
