FAQ

This unit is designed for size 00 fuses according to DIN 43620 and IEC 60269. It is typically used with Siemens SITOR gR/gS semiconductor fuses up to a maximum rating of 160A.

These categories, defined by IEC 60947-3, describe the intended use. AC-22B/DC-22B refers to switching of mixed resistive and inductive loads, including moderate overloads. AC-23B/DC-23B is for frequent switching of motor loads or other highly inductive loads, which is a more demanding application.

The Siemens 3NP5 series is designed for base mounting. It is typically screwed directly onto a mounting plate within an electrical enclosure or control panel.
