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


Is it possible to know in advance when a power failure will happen?

Can you reduce outage times to a minimum?

And: can you locate cable faults at all without disconnecting the consumer from the mains?

YES, Megger can. And so can you – with SmartFuse250 (SFC250).

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

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
