In most cases, for Sub Distribution Board, a MOV may be acceptable. Generally for mains switchboards GDT or combined GDT & MOV protection is required.

For specific requirements, please contact us with the required specification, or detailed application and we will work with Raycap to select and offer the correct GDT component. (Or MOV if applicable).

Please note we also offer a range of AC and DC Surge Protection Devices (SPD) to suit almost any application.
