SmartFuse 2

Overview

Discontinued SmartFuse 2 (SmartFuse2, SFC2) is a fault locator and monitor for low voltage grids. It is described as a multifunctional electronic circuit breaker system for load currents up to 250 A. The device replaces conventional HRC standard fuses and is compatible with NH02 and NH03 fuse holders, offering a modular multipolar design. The SmartFuse 2 monitors current and voltage progression in real time and continuously records the data. It reports events via the mobile phone network (GSM, 3G), WiFi, or LAN and can be configured to automatically restore power. Technical documentation available includes SFC250_BR_EN.pdf (pdf 1.96 MB), SMARTFUSE250_DS_EN.pdf (pdf 599.79 KB), and SFC250_UG_EN.pdf (pdf 4.91 MB). Firmware releases listed for SFC250 include a latest version 2444 (zip 52.21 MB) and a beta 2450 (zip 52.22 MB). Used for testing and monitoring low voltage power grids, providing real-time analysis of current and voltage progression. The SmartFuse 2 gives early warning of impending grid overload, can automatically restore the power supply, and aims to minimise downtimes. It performs cable fault locating and pinpointing, including locating cable faults with households connected, and reports events over GSM, 3G, WiFi, or LAN.
