Comprehensive and scaleable bus and breaker fail protection for LV, HV and EHV busbars. The B90, a member of the UR Family, features integrated protection and breaker failure for re-configurable LV, HV, EHV multi-section busbars up to 24 feeders. Use one or more B90s together to build a sophisticated protection system that can be engineered to meet the specific application requirements. The B90 performs fast and secure low impedance bus protection with sub-cycle tripping time averaging 0.75 cycles.
The MGC1000 are microprocessor based, digital type, generator protection relays which provide thermal protection for three phase generators, phase fault, ground fault, and unbalanced current protection.
