## Summary description

Surge arrester Noark Ex9UEP 111761 is a Type I+II, three-pole (3P) device rated for 1200V DC, designed for unearthed (IT) photovoltaic systems. It provides protection against lightning and switching surges in solar PV arrays by diverting transient overvoltages. Suitable for installation in DC combiner boxes or PV string protection to improve system safety and component longevity.

## Long description

Surge Arrester Noark Ex9UEP 111761 Type I+II 1200V DC 3P for Unearthed PV Systems, gray is a three-pole surge protection device designed for unearthed (IT) photovoltaic installations. Rated for 1200 V DC and combining Type I and Type II protection, this device diverts transient overvoltages from lightning strikes and switching events away from sensitive PV modules and inverters. Its compact three-pole design fits into DC combiner boxes or string-level protection locations to enhance system safety and prolong component life.
Advantages
The device integrates both Type I and Type II protection in a single unit, providing a coordinated response to both high-energy lightning pulses and lower-energy switching surges. Its three-pole configuration is tailored for unearthed PV arrays, enabling symmetrical protection across all DC conductors without relying on a grounded system reference. Constructed for outdoor photovoltaic applications, the arrester helps reduce downtime and maintenance by limiting surge-related damage to modules, wiring and inverters.
Suitable for
Unearthed (IT) photovoltaic string and array protection
Installation in DC combiner boxes and string-level protection cabinets
Systems requiring combined Type I+II surge protection for lightning and switching events
Solar farms and commercial rooftop installations with 1200 V DC maximum system voltage
Key specifications
Protection type: Combined Type I + Type II surge protection
Poles: 3-pole configuration for DC conductors
Rated voltage: 1200 V DC maximum operating voltage
Application: Designed for unearthed (IT) photovoltaic systems
Typical mounting: Suitable for installation in DC combiner boxes or string protection modules
How to use
Install the surge arrester according to local electrical codes and the PV system design, locating it at the DC combiner box or string protection point where transient suppression is required. Ensure correct connection of each DC conductor to the corresponding pole of the device and follow recommended clearances and tightening torques for secure electrical and mechanical connections. Verify polarity and system voltage compatibility before energizing the PV array. After installation, perform standard commissioning tests to confirm continuity and correct operation of the PV string and protective device.
Usage recommendations
Place the arrester as close as practical to the point of entry of the DC conductors into the installation enclosure to minimize lead length. Periodically inspect the device and surrounding connections for signs of thermal stress or surge-related operation and replace if protective components show evidence of degradation. Coordinate surge protection levels with inverter and module manufacturer guidance to ensure overall system compatibility.
