## Summary description

DC surge protector arrester, 2-pole, rated for 1000 V DC. Designed to protect DC circuits and equipment from transient overvoltages and lightning-induced surges. Suitable for use in solar photovoltaic systems, battery banks, telecom and industrial DC installations. Provides reliable surge diversion between poles and to ground when integrated into a protective system.

## Long description

QOLTEC Surge protector arrester DC 2-pole 1000 V is a compact protective device designed to limit transient overvoltages in DC installations. Intended for use where direct current circuits require protection from lightning-induced surges and switching transients, this two-pole arrester provides surge diversion between the positive and negative poles and, when integrated into a full protective scheme, to protective earth. The device is suitable for photovoltaic arrays, battery banks, telecom DC feeds and other industrial DC systems operating up to 1000 V DC.
Advantages
The 2-pole design offers coordinated protection of both conductors in a DC circuit, reducing the risk of damage to connected equipment. Its compact form factor allows installation in distribution enclosures and combiner boxes with limited space. The device is engineered for reliable operation under transient events and integrates into standard protection architectures for solar and industrial applications.
Suitable for
 Photovoltaic (PV) arrays and combiner boxes
 Battery banks and DC energy storage systems
 Telecommunication DC supply lines
 Industrial DC control circuits and power distribution
Key specifications
 Poles: 2-pole configuration for DC circuits
 Nominal voltage rating: up to 1000 V DC
 Function: transient overvoltage diversion between poles and to earth when used in a protected system
 Mounting: suitable for installation in enclosures and combiner boxes (compact design)
 Application environment: solar PV systems, battery and telecom DC installations, industrial DC systems
How to use
Install the surge protector arrester in the DC circuit according to site wiring diagrams and applicable electrical standards. Mount the unit inside the distribution or combiner enclosure close to the point where the DC conductors enter the protected space, ensuring short conductor runs to the device for effective surge diversion. Connect the two poles to the positive and negative conductors of the DC circuit and provide a low-impedance connection to protective earth if the overall system design requires earthing for surge diversion. Verify compatibility with system voltage and follow local regulations and safety practices when performing installation and commissioning.
Usage recommendations
Use this arrester as part of a layered surge protection strategy: combine it with upstream and downstream protective devices and system grounding measures. Periodically inspect connections and the physical condition of the device after severe transient events and during routine maintenance to ensure continued protection performance.
