NewTrend · AC surge protective device
Product overview
The ZG40-C is a two-pole pluggable MOV surge protective device for AC distribution circuits. This listing offers the 275 V AC, 20/40 kA Type 2 configuration. The original manufacturer photographs are shared 385 V samples within the listed 275/385/420 V family; those photographed markings are retained unchanged.

Replaceable MOV module
The pluggable module allows inspection and replacement after isolation. The original reference shows the module and fixed base.
Visual warning window
The original illustration identifies green as normal working condition and red as a state requiring replacement. The “Red=Replace” marking is retained on the product.
DIN-rail mounting
Mount on a 35 mm rail in an appropriate enclosure. Keep access to the terminals and replaceable protection modules.
Wiring
The original two-pole wiring diagram identifies L, N and protective earth. Follow the grounding and protection-coordination requirements of the installation.
Product markings
The annotated original reference identifies the input terminals, status windows, model, voltage, discharge-current ratings, protection level and protective-earth connection.
Original family technical table
The original table retains the family voltage and discharge-current choices. The source’s CE notation is a reproduced marking, not an independent certification claim for a rebranded product.
Dimensions
The original dimension drawing includes the 90 mm height,36 mm width,67 mm side dimension,48 mm base reference and 35/45 mm mounting references.
Typical applications
AC distribution panels, household/commercial equipment and control circuits needing coordinated protection against transient surge voltages. The 275 V value is the SPD voltage rating and must suit the circuit design.
