Lorentz PV Disconnect Protection 440-40-3 IP54 40A 3 strings

Product Description

The Lorentz PV Disconnect 440-40-3 is a DC protection box with integrated isolator, designed for professional solar installations with up to 3 parallel strings. It supports a maximum voltage of 440 VDC and up to 40 A total current. It is ideal for Lorentz pumping systems from PS2-150 to PS2-4000, and can integrate optional surge protection (SPD) to increase safety in rural, agricultural, or industrial environments.

Main Features

• Up to 3 strings with a maximum current of 15 A per string
• Maximum voltage: 440 VDC, total current up to 40 A
• Integrated DC switch-isolator in the enclosure
• IP54 protection against dust and splashes
• Compatible with SPD modules (MidNite Solar) depending on the controller
• Lightweight: only 1.6 kg without SPD, easy to mount on surfaces

Advantages or Benefits

• Centralized string disconnection for safe maintenance
• Compatible with all Lorentz PS2 systems (from 150 to 4000)
• Option for integrated surge protection in the same box
• Simple installation with professional PG and M16 cable glands
• Prepared to comply with CE regulations in demanding installations

Purpose or Applications

The PV Disconnect 440-40-3 is designed for small and medium-scale solar installations, with up to 3 photovoltaic strings connected in parallel. It is perfect for Lorentz pumping systems in wells, irrigation, livestock, or rural homes, where quick disconnection and the possibility of surge protection are required.
