W-F-1814/60
REQUIREMENTS:
Interface and physical dimensions: See figure 1. Physical: Nonrenewable.
Terminals: Ferrule type:
Material: Brass, copper or copper alloy.
Strength: 5 pound-inches torque between body and ferrules. Body:
Insulating material: Ceramic, melamine-impregnated glass fiber, or the equivalent. Electrical:
Voltage: 600 volts or less. Frequency: 48 Hz to 60 Hz . Current: See table I.
Current carrying capacity: 100 percent indefinitely with temperature rise not to exceed 55°C above ambient on the ferrules.
Overload interrupt: Shall interrupt within 1 hour at 135 percent of rated current and within 6 minutes at 200 percent of rated current.
Interrupting capacity rating: 200,000 amperes rms symmetrical at 600 volts, 60 Hz and a power
factor of 20 percent or less. Closing angle shall be essentially at the zero of the voltage wave (maximum offset) or later, to produce start of arcing within 30 electrical degrees prior to system peak voltage.
Threshold ratio: 30 maximum.
Maximum peak let-thru current: See table I. Maximum clearing I2T: See table I.
Applicable fuseholders: Class J for ferrule type fuses in accordance with UL 4248-8. Part or Identifying Number (PIN): See table I.
