Product details

The Siemens 3NJ6304-2AA0.-.... is a SENTRON 3NJ63 switch disconnector with fuses, rated 160 A, 4-pole, AC23B 500 V, with a 55 kA breaking capacity at AC 500 V. It is designed for motor-drive operating duty — the AC23B rating means it can switch motor loads including starting and plugging/ inching, not just resistive heating.

Integration Notes

This is an in-line design, pluggable NH00 fuse holder — the NH00 fuse size is the smallest standard NH fuse, common in panel-building for branch-circuit protection up to 160 A. The 4-pole configuration (3 phases + neutral) suits three-phase motor feeders where the neutral must be switched or disconnected.
