Lorentz PV Disconnect Protection 1000-40-5 IP54 40A 5 strings

Product Description

The Lorentz PV Disconnect 1000-40-5 is a professional solar disconnect box designed to group up to five photovoltaic strings in parallel. It incorporates a 40 A DC switch-disconnector and is optimized to operate at up to 1000 VDC, meeting the requirements of demanding solar pumping systems such as Lorentz PSk and PSk2. Its compact and robust design, with IP54 protection, ensures safe and effective disconnection in agricultural and industrial environments.

Main Features

• Supports up to 5 strings in parallel
• Total maximum current: 40 A, voltage up to 1000 V DC
• Integrated DC switch for safe disconnection
• IP54 enclosure resistant to dust and splashes
• Inputs/outputs with PG11 and M16 cable glands for professional wiring
• Compatible with Lorentz combiner boxes and protections

Advantages or Benefits

• Allows quick disconnection of all strings in case of maintenance or emergency
• Prevents risks from direct handling of high-voltage photovoltaic connections
• Facilitates string grouping in large-scale installations
• Complies with CE regulations for installations up to 1000 VDC
• Prepared for expansion with combiner boxes or SPD

Purpose or Applications

The PV Disconnect 1000-40-5 box is designed for solar pumping installations with multiple strings, especially in agricultural, industrial, or high-flow projects with Lorentz PSk or PSk2 pumps. Its function is to group and disconnect up to 5 photovoltaic strings at a single point, increasing system safety and efficiency.

Technical Specifications

Compatibilities
