Circuit protector for industrial power

The RS15 KTK KLM is a 20 A fast‑blow fuse designed for line protection in electrical installations. Supplied in a box of 20 pieces, it suits technicians and maintenance teams who need reliable over‑current safeguarding for industrial equipment.

Ceramic tube construction and cylindrical fit

A Ø10 × 38 mm ceramic body provides high thermal stability and fits standard cylindrical fuse holders. The robust tube resists vibration and heat, allowing straightforward replacement during scheduled servicing without special tools.

Rated for 500/690 V systems

The fuse interrupts fault currents up to 100 kA at 500 V and 50 kA at 690 V. Circuits operating above these voltages or requiring higher breaking ratings fall outside its certified limits and must use alternative protection.
