The M-4172 Digital Motor Bus Transfer system provides automatic and manual transfers of motor bus systems in low voltage switchgears in power plants and industrial processing plants, to ensure process continuity. It automatically selects fast, in-phase, residual voltage, and fixed time motor bus transfers, based on varying system conditions. It is applicable for both one way and bi-directional manual and automatic transfers and can be expanded to accommodate multiple breaker configurations. Additional features of the M-4172 include:
Integrated control, supervisory functions, sequence of events, and oscillograph recording in one device.
Extensive commissioning tools, including ringdown analysis.
