Wengart DC 1000V Surge Protective Device (SPD), 3-Pole 20-40kA Lightning Arrester, Photovoltaic Surge Protector for Solar PV System & Off-Grid Power, 36mm DIN Rail Mount, Modular Replacement Design

Description

• Ultimate System Protection: Specifically engineered for DC 1000V Solar PV systems. This 3-pole Surge Protective Device (SPD) provides robust lightning and surge protection, shielding your expensive solar inverters and controllers from atmospheric overvoltage and switching surges
• High-Capacity Lightning Arrester: Features a nominal discharge current (In) of 20kA and a maximum discharge current (Imax) of 40kA. Designed to handle high-energy surges effectively, ensuring a safe voltage level remains for your downstream equipment
• Easy Modular Replacement: The pluggable module design allows for quick maintenance without disconnecting the wiring. If a module reaches its end-of-life, simply swap the cartridge while keeping the base on the DIN rail, saving time and labor costs
• Instant Status Monitoring: Features a clear color-coded visual indicator: Green means "Operational" and Red means "Damaged - Replace Immediately." Allows for easy safety inspections during routine system maintenance
• Standard DIN Rail Mount: Compatible with 36mm (2-module) wide standard 35mm DIN rails. Its compact, flame-retardant housing fits perfectly into combiner boxes and distribution panels for DIY solar projects and industrial power stations

Professional DC 1000V Surge Protection for Your Solar Investment

Lightning strikes and power surges can destroy your solar investment in milliseconds. Our DC 1000V Surge Protective Device (SPD) is your first line of defense against overvoltage. Designed for high-voltage DC circuits, this 3-pole lightning arrester provides the high-level security required for modern off-grid and grid-tied solar PV systems.
Precision Engineered for Safety
Unlike generic AC protectors, this DC-specific SPD is built to handle the unique characteristics of direct current. With a response time in the nanoseconds, it rapidly clamps the voltage during a surge, directing the excess energy safely to the ground before it can reach your solar inverter or battery bank.

Technical Specifications
Rated Voltage (Uc): DC 1000V Poles: 3-Pole (L+/L-/PE) Nominal Discharge (In): 20kA Max Discharge (Imax): 40kA Protection Level (Up): 3.2kV Installation: 35mm DIN Rail Mount (36mm width) Material: Flame-Retardant UL94-V0 Housing

Why Professionals Choose Our SPD?
Fast Response Time: Activates in <25ns to intercept surges before they damage sensitive electronics. Pluggable Modules: No need to rewire the entire box; just replace the burnt-out cartridge when needed. Thermal Disconnect: Built-in thermal disconnector prevents fire hazards at the end of the device's life cycle.

Frequently Asked Questions (FAQ)

Q: Is this for a 12V or 24V system?
A: While it can work on lower voltages, it is specifically optimized for high-voltage strings (up to 1000V DC) commonly found in large solar arrays.
Q: Do I need to ground this device?
A: Yes! To provide effective lightning protection, the Ground (PE) terminal must be connected to a reliable earth grounding system.
