1250A General Duty AC Surge Protective Devices

Bourns 1250A General Duty AC Surge Protective Devices (SPDs) offer a 150V to 690V operating voltage range and large surge energy capability of up to 50kA per mode. These devices are designed to protect high-risk electrical service entrances and branch panels and are intended to be installed at the front end of the installation in the main switchboard. 1250A series devices can be configured for common and differential-mode protection in single- and three-phase applications. Bourns 1250A General Duty AC SPDs suit all power circuits, heavy industrial applications, and EV charging stations.
