NewTrend · DC photovoltaic surge protective device
Product overview
The ZG40-PV is a pluggable DC surge protective device for photovoltaic distribution circuits. The illustrated three-module unit has positive, protective-earth and negative terminals. Its nameplate specifies 1200 V DC, In 20 kA, Imax 40 kA and Up ≤4.0 kV.

Visual status indication
The green window identifies normal working condition. A red window indicates a failed protection module that requires replacement according to the installation and maintenance instructions.
Replaceable modules
The original rear-view illustration shows the removable-module arrangement for inspection and replacement. Disconnect and isolate the circuit before servicing.
Original family parameter reference
The source family table below lists 500, 800 and 1000 V DC versions and a 3.2 kV protection level. These are separate family references; they do not override the 1200 V / ≤4.0 kV nameplate of the unit offered here. The CE notation in the original table is retained as a source marking, not an independent certification claim.
Product markings and terminals
The annotated reference identifies the module status windows, model, discharge-current ratings, protection level, input terminals and earth connection. Select and wire the device for the DC circuit and its grounding arrangement.
Dimensions
The original drawing identifies the mounting and enclosure reference dimensions. Read the drawing for panel layout and allow access to terminals and removable modules.
Typical applications
Use in photovoltaic DC distribution and combiner arrangements requiring surge protection. The protective-earth connection and coordination with circuit protection must follow the project design and device terminal markings.
