New - gR operating class with and without striker Eaton’s Bussmann series FWP 14x51 mm class gR fuses provide full range overload and short-circuit protection and are used to protect AC/DC drives and semi conductors. They are available with an optional striker to provide local indication of fuse status or work in the CH14 modular fuse holder to provide remote fuse indication capabililty. aR operating class with and without striker Eaton’s Bussmann series FWP 14x51 mm class aR fuses provide short-circuit protection and are used to protect AC/DC drives and semi conductors.

Description: Ferrule style high speed fuses with and without indicating striker. Dimensions: See dimensions illustrations. Ratings: Volts: 690Vac (IEC) — 700Vac (UL) — 800Vdc (5-50A) Amps: 1-50A IR: 200kA RMS Sym. — 50kA @800Vdc Agency Information: CE, UL Recognition, CSA Component Acceptance for versions without indicator only. Electrical Characteristics Total Clearing I2t The total clearing I2t at rated voltage and at power factor of 15% are given in the electrical characteristics. For other voltages, the clearing I2t is found by multiplying by correction factor, K, given as a function of applied working voltage, Eg, (rms) Arc Voltage This curve gives the peak arc voltage, UL, which may appear across the fuse during its operation as a function of the applied working voltage, Eg, (rms) at a power factor of 15%. Power Losses Watts loss at rated current is given in the electrical characteristics. The curve allows the calculation of the power losses at load currents lower than the rated current. The correction factor, Kp, is given as a function of the RMS load current, Ib, in % of the rated current.
