Solid-State Circuit Breakers (SSCBs)

Redefine circuit protection for the 800V era

Solid-state circuit breakers (SSCBs) are high speed, controller managed DC switches that are emerging as a crucial protective technology for high density 800 VDC data center power architectures. By using Silicon Carbide (SiC) switches instead of traditional mechanical contacts, SSCBs can interrupt fault currents in sub millisecond timeframes without generating dangerous arcs.

Precise Busbar Monitoring: Coreless field current sensors enable highly accurate monitoring and live fault detection, providing the critical telemetry needed to help keep AI workloads running.

Streamlined Gate Drive: Power-Thru™ isolated gate drivers provide precise control and strong noise immunity for SiC switches, helping keep your solid-state breaker stable under demanding 800 V conditions.

Stable Auxiliary Power: ClearPower™ regulators provide stable, efficient power to critical control circuitry to ensure your solid-state circuit breaker stays ready to respond.
