PV fire disconnect switch 30A, MV, undervoltage release delayed 24VDC SOL30-SAFETY/2MV-U(24VDC) 172945

DC Disconnect Switch for Photovoltaic Installations

This DC disconnect switch, designed for photovoltaic systems, provides effective disconnection of the circuit in case of failure or the need to perform maintenance work. Designed with safety and reliability in mind, it meets the requirements of modern PV installations. Its construction allows for quick and safe installation, and its compact dimensions allow for installation even in limited spaces.

Features and Application

The SOL30-SAFETY/2MV-U(24VDC) device is a single-pole disconnect switch with an undervoltage release characteristic with a delay (MV), powered by 24VDC. It is designed to operate with a rated current of 32A and a voltage of up to 1000V DC. Its main task is to function as a maintenance disconnect switch, allowing for safe isolation of a fragment of the photovoltaic installation during servicing or modernization. Thanks to its IP65 protection class, it is resistant to weather conditions and dust, allowing for installation both indoors and outdoors. Equipped with cable lugs, it provides a solid and durable connection of the conductors.

Advantages and Benefits

• Safety: Provides effective protection against short circuits and overloads in the photovoltaic installation.
• Fast reaction: Undervoltage release characteristic with a delay (MV) allows for a quick reaction in case of a voltage drop, minimizing the risk of damage.
• Versatility: Possibility of mounting on a plate and high resistance to weather conditions (IP65) make it suitable for various applications.
• Durability: Made of high-quality materials, guarantees long-lasting and reliable operation.
• Connection capacity: Rated connection capacity at 400V is 30kW, making it suitable for most standard PV installations.
• Built-in voltage release: Optional voltage release increases the functionality of the device and allows it to be adapted to specific installation requirements.
• Compact dimensions: Dimensions 165 x 135 x 255 mm make installation easier even in tight spaces.
• Mechanical resistance: Solid construction provides resistance to mechanical damage during transport and operation.

The rated continuous current is 32A, and the rated operating voltage is 690 ... 690 V. The maximum rated operating voltage (Ue AC) is 1000 V, and the degree of protection (IP) is IP65. The rated withstand short-circuit current (Icw) is 0.36 kA, the device has one pole and cable lugs for connecting conductors.

This disconnect switch is an ideal solution for both professional photovoltaic system installers and end-users looking for a reliable and safe element protecting their investment. Its solid construction and compliance with standards ensure long-lasting and trouble-free operation.
