MEGGER SmartFuse SFC 250 Monitoring and Fault Location in Low-Voltage Grids

SFC250, a multifunctional electronic circuit-breaker system for load currents up to 250 A is Megger’s solution for low voltage power grids.

• Real-time monitoring and analysis of current and voltage progression
• Early warning of impending grid overload
• Automatic restoration of power supply
• Minimised downtimes
• Cable fault location with households connected
• Modular multipolar design

The SFC250 circuit-breaker system:

• replaces conventional HRC standard fuses and is compatible with NH02 and NH03 fuse holders
• offers the maximum flexibility through modular multipolar design
• monitors the current and voltage progression in real time, continuously records the data and reports events via the mobile phone network (GSM, 3G), WiFi or LAN to the user
• sends the user an early warning if grid overload is threatened
• can be configured to automatically restore the power
• can locate cable faults without the need to disconnect consumers from the mains
