20mm Ceramic Anti Surge Fuses

A range of 20mm slow blow anti surge ceramic fuses with high breaking capacity designed to prevent damage to electronic and electrical equipment. RoHS compliant and carrying international approvals. Many more options available non stock.Fuses allow electric current to pass through them until the amount of current goes over the fuse's rating. At that point the fuse "blows" and stops the flow of electric current.A fuse is a SAFETY DEVICE. You should always replace a blown fuse with the same type. Replace fast acting with fast acting and slow blow with slow blow. Always replace with the same current rating and the same or higher voltage rating.Slow blow fuses are ideal for circuits with a transient surge or power on current inrush. The circuits include; motors, transformers, incandescent lamps and capacitor loads. The inrush can be 20 times the normal current level. Slow blow fuses allow close ratings of the fuse without "nuisance" openings. Typically you should rate slow blow fuses from 125% to 150% of the circuits full load amperes.
