  • 500/690 V dual voltage rating suits multiple circuits
  • 100/50 kA breaking capacity handles high fault energy
  • 10 x 38 mm ceramic tube fits standard holders

Fuse specifications and intended use

These fuses are 3 A fast-blow ceramic tube devices rated for 500 V AC and 690 V AC with a breaking capacity of 100 kA at 500 V and 50 kA at 690 V. They are supplied in a box of 20 pieces and are designed for line protection in electrical circuits requiring high interrupting capability.

Compatibility checks before ordering

Verify that your fuse holders accept cylindrical ceramic tubes measuring 10 mm in diameter and 38 mm in length. Confirm that the circuit voltage does not exceed the rated 500 V AC or 690 V AC values and that the prospective short-circuit current stays within the stated breaking capacities. Ensure the 3 A rating matches the protective requirement of the equipment being safeguarded.

Behaviour under sustained load

The fast-blow aR characteristic causes the element to open quickly when current exceeds the rated value, limiting energy let-through during a fault. The ceramic body and high breaking capacity allow the fuse to interrupt large fault currents without rupture, maintaining circuit integrity during prolonged overcurrent events rather than only brief transients.

Questions about this item

What is included in the box and does anything need to be purchased separately?

The box contains 20 cylindrical ceramic tube fuses rated at 3 A, 500/690 V with 100/50 kA breaking capacity; no additional components are required for installation.

Which version or capacity should I choose for my application?

This single listing provides the 3 A fast-blow RS15 KTK KLM model; select it when your circuit requires exactly 3 A of over-current protection at the stated voltage and interrupting ratings.

What does the 500/690 V rating mean once the fuse is installed in equipment?

It indicates the fuse can safely interrupt faults on systems up to 500 V AC or 690 V AC, with a 100 kA AC and 50 kA DC breaking capacity, in a 10 × 38 mm ceramic body.
