Fire disconnect switch SOL30-SAFETY for 6 PV strings, MV, 230VAC SOL30X6-SAFETY-MV-U(230V50HZ) 168105

DC Disconnect Switch for Photovoltaic Installations

This SOL30-SAFETY DC disconnect switch is designed for the safe disconnection of DC circuits in photovoltaic systems. It provides effective protection of the installation, enabling quick and controlled disconnection of power in the event of a failure or fire. The device is particularly useful between PV modules and the inverter, where a rapid response is critical.

Design and Application

The SOL30-SAFETY disconnect switch for 6 strings, with a rated current of 30A, has been designed for ease of installation and use. Made of durable plastic, it has an IP65 protection rating, which guarantees resistance to weather conditions and dust. Remote triggering using a built-in undervoltage release (230V, 50Hz) with a 0.6s delay minimizes the risk of false alarms caused by short-term voltage fluctuations. Additionally, an auxiliary contact (1NO and 1NC) indicates the status of the disconnect switch, making it easier to monitor the installation status.

• Safety first: Quick disconnection of the DC circuit in the event of a failure or fire minimizes the risk of damage and ensures the safety of people.
• Versatility: Designed to work with installations with a rated voltage of up to 1000V DC.
• Convenient installation: Complete device in a housing, pre-wired and ready to connect – saves time and simplifies installation.
• Status indication: Auxiliary contact informs about the current status of the disconnect switch (on/off), which facilitates diagnostics and system monitoring.
• Durability: Made of high-quality materials, resistant to weather conditions (IP65).

Design Features and Parameters

The disconnect switch has two poles and the possibility of mounting on a plate. It is equipped with a knob as an actuator and screw connections of the main contacts. Its construction ensures reliable operation in a wide temperature range (from -25°C to +60°C). The device meets the IEC/EN 60947-3 standards, which confirms its compliance with safety requirements. The use of a locking mechanism prevents accidental switching on of the device after emergency shutdown. Additionally, the ability to lock in the OFF position with a padlock increases the level of installation security.
