Low-voltage systems distribute electrical energy to machinery, motors, lighting and other loads within a facility. Main and sub-distribution panels, motor control centres, source transfer arrangements and power factor correction solutions are configured according to the facility’s electrical and operational requirements.

When correctly selected, circuit breakers and fuses provide overcurrent and short-circuit protection. Contactors control electrical loads, disconnectors provide safe isolation and surge protection devices limit transient overvoltages. Ground-fault and residual-current protection is designed according to the facility’s earthing arrangement and the protection requirements of the application.

Rated current, short-circuit withstand capability, temperature rise, degree of protection and maintenance access are evaluated together during panel design. Metering and communication options support energy consumption monitoring. Backup supply and transfer scenarios are determined according to the interruption time that critical loads can tolerate.
