Switch Disconnector with Fuses – 3NJ6313-4AC0.-....
SENTRON 3NJ63 switch disconnector with fuses, in-line design, NH1 250 A, 3-pole, AC23A 500 V, 120 kA. The part includes an EFM 20 electronic fuse monitoring module and is designed for motor drive operating, meaning it can be switched under load by a motor operator rather than requiring manual throw.
RoHS compliance is documented since 27 September 2019, and REACH candidate-list disclosure is available.
Integration Notes
The in-line design mounts directly into a switchgear lineup or enclosure busbar system — no DIN-rail adapter needed. The NH1 fuse base accepts standard NH1 fuse links up to 250 A. The EFM 20 module provides a signal output for blown-fuse indication, which can be wired into a PLC or annunciator for remote fault visibility.
