TBU® Circuit Protection Devices

Bourns TBU^® Circuit Protection Devices block transients in nanoseconds through a current-disconnecting mechanism instead of diverting or shunting the surge to ground. These high-speed surge protection components are designed to protect against faults caused by short circuits, AC power cross, induction, and lightning surges. Bourns TBU Circuit Protection Devices are resettable for full functionality after multiple fault events and ideal for telecommunications, industrial, and data communications systems.
