Application and purpose

This ceramic tube fuse provides fast-acting line protection for circuits rated up to 10 amps. It is intended for technicians and engineers who need reliable over-current interruption in industrial or automotive electrical systems. The aR characteristic ensures rapid response to fault conditions. Buyers requiring slower time-delay characteristics or higher continuous current ratings should select a different device.

Capacity and headroom

Each fuse carries a 10 amp nominal rating and is designed for systems operating at 500 or 690 volts. The breaking capacity reaches 100 kiloamps at 500 volts and 50 kiloamps at 690 volts, giving substantial headroom for high prospective fault currents. A box contains 20 pieces for spares or volume installation. Circuits exceeding the 10 amp rating or the stated voltage limits will not be protected correctly.

Physical and electrical limits

The cylindrical body measures 10 millimetres in diameter by 38 millimetres in length, fitting standard Ø10*38mm fuse holders. The ceramic tube construction supports the high interrupting ratings but offers no visual indication of element status after operation. The fast-blow aR curve limits suitability for loads with high inrush currents such as motor starts or transformer energisation. Holders and wiring must be rated for the full 690 volt and 100 kiloamp prospective short-circuit level.

Questions about this item

Will the 10 A fast-blow RS15 fuse protect the existing 500 V generator wiring without nuisance trips?

The fuse is rated 10 A at 500/690 V with a 100/50 kA breaking capacity, so it will interrupt fault current on that generator circuit while carrying normal load.

How can I verify the ceramic tube is intact and the element has not blown after installation?

With power isolated, a continuity test across the 10×38 mm end caps will show a closed circuit on a good fuse and open circuit on a blown one.

Does the box contain twenty individual 10 A fuses or do I need to order them separately?

The selling unit is a box of 20 pieces, so all twenty 10 A RS15 KTK KLM fuses are included.
