Low voltage switchgears interrupt voltages less than 1000 volts AC. LV switchgear offers electrical protection, isolation and switchgear control.
Protection:
- Of people in case of an insulation failure – circuit breakers, fuses, residual devices, and/or permanent monitoring
- Of motors, appliances from overheating – Thermal relays designed to match needs of motor use
- Of circuit elements from overload and short circuit currents – circuit breaker, fuses
Isolation separates the circuit from the energized system allowing employees to work on the isolated area in safety, while allowing the rest of the systems to continue to operate normally.
