Total Solution to Earthing & Lightning Protection |

9AKK106354A3360

Combined Type 1 and 2 tested protector (to BS EN 61643) for a Photovoltaic

PV solar panel system that is on a building where a structural Lightning

Protection System (LPS) is employed, for equipotential bonding. For use at

boundaries up to LPZ

to protect against flashover (on the DC side of

the DC-AC inverter) through to LPZ 2 to protect the PV system from damage.

Specific systems protection

ESP PV Series

IMPORTANT:

The primary purpose of lightning current or equipotential bonding mains Type 1 Surge Protective Devices (SPDs) is to prevent dangerous sparking caused by flashover to protect against

the loss of human life. In order to protect electronic equipment and ensure the continual operation of systems, transient overvoltage mains Type 2 and 3 SPDs such as the ESP M1 or ESP D1 Series

are further required, typically installed at downstream sub-distribution boards feeding sensitive equipment. IEC/BS EN 62305 refers to the correct application of mains Type 1, 2 and 3 SPDs as a

coordinated set. For further information, please refer to the Furse Guide to BS EN 62305 Protection against Lightning.

Installation

Protector should be installed in the main distribution board

with connecting leads of minimal length. The protector should

be fused and is suitable for attachment to a 35 mm top hat

DIN rail. Install in parallel to the DC supply of the DC-AC

inverter via fuses.

Features & benefits

–– Enhanced protection (to IEC/BS EN 62305) offering low

let-through voltage further minimizing the risk of flashover

creating dangerous sparking or electric shock

–– Repeated protection in lightning intense environments

–– The varistor based design eliminates the high follow current

(If) associated with spark gap based surge protection

–– Compact, space saving design

–– Indicator shows when the protector requires replacement

–– Remote signal contact can indicate the protector’s

status through interfacing with a building

management system

Application

Use on the DC side of the DC-AC inverter for protection

against partial direct or indirect lightning strikes. ESP Type

1 AC mains protectors (e.g. ESP 415/III/TNS) are further

required at the AC side of the DC-AC inverter.
