RS15 KTK KLM 32A line protection for industrial

These cylindrical ceramic-tube fuses carry a 32 A rating and a fast-blow aR characteristic. They are designed for semiconductor and line protection in equipment rated up to 500 V AC or 690 V AC. Each box supplies twenty pieces for maintenance stock or panel builds.

Sustained-load behaviour

The aR curve interrupts fault current rapidly to limit let-through energy during overloads. Rated breaking capacity reaches 100 kA at 500 V and 50 kA at 690 V, so the fuse remains intact while clearing heavy short-circuit events without nuisance opening under normal cyclic loads.

Practical limits of the Ø10 × 38 mm form factor

The 10 mm diameter by 38 mm length fixes the fuse to holders and fuse blocks built to this envelope. Voltage rating drops above 690 V and current rating is fixed at 32 A, so circuits needing higher continuous current or different mounting dimensions require a different fuse series.

Questions about this item

How much heat does a 32 A ceramic fuse generate when it runs continuously?

The fuse is rated for 32 A at 500/690 V; normal operation produces only the heat from its own resistance, and the ceramic tube dissipates it without active cooling.

What holder or block is needed to install these Ø10×38 mm fuses?

They require a standard 10 × 38 mm cylindrical fuse holder or fuse block rated for at least 690 V and the available fault current.

Can these fast-blow fuses protect older equipment that uses slower gG types?

The aR fast-blow characteristic clears faults faster than gG fuses, so coordination must be checked; they may open on inrush currents that older gear tolerates.
