Standard fuses

For the simple short-circuit protection of semiconductors, we offer the aR-class SITOR fuses. The key feature of these fuses is optimum short-circuit protection of power semiconductors using proven technology.

Our SITOR 3NE1 gR-class, dual-function fuses are designed to provide optimum overload protection of lines and short-circuit protection of semiconductors.

In connection with the tried and tested 3KL and 3NP switch-disconnectors, not only do these fuses provide protection that reduces space and cost requirements, they are also UL-certified.
