Fire disconnect switch SOL30-SAFETY for 4 PV strings, MV, 230VAC SOL30X4-SAFETY-MV-U(230V50HZ) 168103

Photovoltaic DC Disconnect Switch

This SOL30-SAFETY DC disconnect switch, designed for photovoltaic systems, provides safe and effective disconnection of power in the event of a fault or the need for maintenance. Model SOL30X4-SAFETY-MV-U(230V50HZ) is dedicated to working with four PV strings, offering comprehensive installation protection. The device is particularly important in the context of fire safety, allowing for quick power disconnection if necessary.

Design and Application

The disconnect switch is designed for panel mounting and features a high degree of protection IP65, guaranteeing its reliability in harsh environmental conditions. The complete device in a plastic housing ensures durability and resistance to mechanical damage. It is intended for disconnecting direct current (DC) circuits between the photovoltaic generator and the inverter. The use of a 230V 50Hz undervoltage release allows for remote disconnection of the power supply, increasing the functionality and safety of the system. Additionally, the presence of auxiliary contacts (1 normally open and 1 normally closed) allows integration with monitoring and control systems.

Key Features and Benefits

• Fire safety: Quick and effective disconnection of power in the event of a fire hazard.
• High reliability: Made of durable materials (plastic) and with a high degree of protection IP65, ensuring long-term operation of the device.
• Remote tripping: Possibility of remote disconnection of the power supply using a 230V 50Hz undervoltage release – this facilitates operation and increases safety.
• Versatility: Designed to work with four PV strings, making it an ideal solution for various photovoltaic installations.
• Easy installation: For panel mounting, which simplifies the installation process and integration with existing infrastructure.
• Status indication: Has auxiliary contacts (1NO, 1NC) to indicate the switch status – useful in monitoring systems.
• Rated continuous current: 30A – suitable for most standard photovoltaic installations.
• Locking function: Locked in the OFF position with a padlock locking function - additional protection against accidental switching on.

This disconnect switch is a complete device ready for connection, which significantly reduces installation time and minimizes the risk of errors during assembly. It is a key element of every modern photovoltaic installation, ensuring safety for both users and installers.
