HH*M-B*
This series type of fuses are current limiting "Back-Up" to British or DIN standard for motor protection, and are designed and constructed to well proven concepts developed by SIBA to deal with cyclic loads typical for motor circuits with lower power losses compared to commonly used HV fuses. The fuses are designed for decades of reliable usage and available in voltage ranges of 3.6kV, 7.2kV and 12kV. SIBA HHM series of fuses are current-limiting “Back-Up” class for protection of motor circuits and comply with the following standards; New DIN style 7.2kV tested at 7.65kV, 80kAIR symmetrical.
