Product details

The Siemens 3NJ6303-3AA0.-.... is a SENTRON 3NJ63 switch disconnector with fuses, rated 160 A, 3-pole, AC23A at 500 V, with a 120 kA breaking capacity. It uses NH00 fuse links in an in-line, pluggable design with manual operation.

The AC23A rating (500 V) covers switching of motor loads and other highly inductive loads. The NH00 fuse size is the smallest standard NH fuse format (up to 160 A), common in distribution boards and motor control centers. The in-line design means the fuse links are arranged in a row, saving panel width compared to staggered layouts.

Integration note

This switch disconnector mounts on a mounting plate or DIN rail via the SENTRON 3NJ63 base — verify the NH00 fuse carrier compatibility with your existing fuse links. The manual operating mechanism is side-mounted; allow clearance for the handle swing in the enclosure layout.
