Wengart 1000V DC Surge Protective Device, 3-Pole 30-60kA Lightning Arrester, 36mm DIN Rail Mount, High-Voltage SPD for Solar PV Systems, Inverters & Off-Grid Power Distribution — Open-Box, 5% Off

Proactive Inverter Protection: Shield your high-value solar investments. This DC 1000V Surge Protective Arrester is specifically designed to intercept high-voltage transients and lightning surges before they reach your inverter or battery bank. By providing a safe path to ground, it acts as the primary defense for your Power Distribution and Control Appliances. High-Capacity 30-60kA Discharge: Engineered for extreme conditions. With a nominal discharge current of 30kA and a maximum surge capacity of 60kA, this device handles massive energy spikes with ease. The 3-Pole design ensures comprehensive protection across Positive, Negative, and Ground lines, outperforming standard 2-pole alternatives in high-exposure environments. Nanosecond Response Time: Every millisecond counts during a lightning strike. Our Low Voltage Arrester Device features advanced MOV (Metal Oxide Varistor) technology that reacts in under 25 nanoseconds. This rapid-fire switching ensures that destructive surges are neutralized almost instantaneously, maintaining a stable voltage environment for your delicate electronics. Visual Status Monitoring: Eliminate the guesswork of maintenance. Each module is equipped with a High-Visibility Status Window. A green indicator means your system is fully protected; a red indicator warns that the module has sacrificed itself to save your equipment and requires immediate replacement. This fail-safe design is critical for Lightning Protection management. Seamless DIN Rail Integration: Save space and time in your combiner box. Featuring a compact 36mm DIN Rail Mount footprint, this SPD fits perfectly into standard electrical enclosures. The heavy-duty screw terminals are designed to handle high-torque tightening, ensuring low-resistance connections that prevent heat buildup during continuous DC Applications.

The Invisible Firewall for Your Off-Grid Solar Empire

Static electricity and lightning strikes don't need a direct hit to destroy your solar system. Induced surges from nearby activity can travel through your PV cables, frying the sensitive motherboards of your inverters and charge controllers. The Wengart Surge Protective Arrester Device is built to handle these "invisible killers." Rated for DC 1000V, this 3-pole powerhouse provides industrial-grade Lightning Protection for residential and commercial solar arrays alike.

Advanced Safety Through Sacrificial Engineering
Reliability in power distribution means knowing exactly when your protection is active. Wengart utilizes a modular design with high-energy MOVs that act as a sacrificial barrier. When a surge occurs, the device absorbs the energy and directs it safely to the ground. Our 30~60kA capacity means it can handle multiple smaller surges or a single major event, while the 36mm DIN Rail housing ensures it stays secure and organized within your control cabinet.

Buyer’s Essential Guide (Ensuring Maximum Protection)

Q: Why do I need a 3-Pole SPD for a DC system?
A: Most DC systems use two wires, but a 3-Pole SPD allows you to bond both the Positive and Negative lines to a common Ground. This provides a "balanced" discharge path, ensuring that a surge on either wire is safely neutralized before it enters your inverter.

Q: Does this device require a specific mounting orientation?
A: No, it can be mounted vertically or horizontally on any 35mm DIN Rail. However, ensure that your Ground wire is as short and straight as possible to minimize impedance during a surge event.

Q: How do I know if it’s time to replace the module?
A: Check the visual window regularly. If it has turned RED, the internal protection has been depleted after a surge event. Thanks to the modular design, you can replace the cartridge without re-wiring the entire base, ensuring your Power Distribution stays online.
