Diversified Technologies, Inc. (DTI) has introduced a new family of 12 kV solid state circuit breakers with rated current from 750 to 4000 A that are drop-in replacements for mechanical circuit breakers.
DTI Solid State Circuit Breakers provide microsecond speed switching which is thousands of times faster than mechanical types, have no moving parts, no arcs, and they have low acoustic and magnetic signatures. Fully electronic, they can be programmed to open instantaneously at arbitrary currents, reset after a fault, and can be networked for coordinated switchgear operation.

Unlike systems with mechanical switches, when a DTI Solid State Circuit Breaker experiences a fault there is minimal impact on the load because it is never exposed to high currents, high forces, and damaging energy levels. They permit more efficient power systems by eliminating design for over-load penalties and are ideal for shipboard DC circuit breaker applications.
DTI Solid State Circuit Breakers are priced from $50,000 up, depending upon design requirements and voltage/current ratings up to 1 MW nominal load.
