Lorentz PV Disconnect Protection 440-40-6 IP54 40A 6 strings

Product Description

The Lorentz PV Disconnect 440-40-6 is a solar protection box with integrated DC disconnect switch, designed to group and disconnect up to 6 photovoltaic strings in parallel. It supports a total current of 40 A at 440 VDC and allows optional integration of surge protection (SPD), making it a complete and safe solution for solar pumping installations between PS150 and PS2-4000. Its IP54 enclosure ensures reliable installation in protected outdoor environments.

Main Features

• Supports up to 6 strings with a maximum of 10 A per string
• Maximum total current: 40 A at 440 VDC
• Integrated DC disconnect switch in the box
• IP54 protection suitable for covered outdoor use
• Optional SPD (Surge Protection Device) for maximum safety
• Inputs with M16 and PG11 cable glands for professional wiring

Advantages or Benefits

• Centralized string disconnection for maintenance or emergencies
• Direct compatibility with Lorentz systems from PS150 to PS4000
• Expandable design with internal surge protection
• Improves electrical safety and reduces short-circuit risks
• Enables compliance with technical standards in professional solar projects

Purpose or Applications

The PV Disconnect 440-40-6 box is ideal for solar pumping installations in rural, agricultural, or industrial environments where Lorentz pumps of low to medium-high power are used. It allows efficient control and protection of multiple photovoltaic strings, improving system operability in sensitive environments or those exposed to storms.
