It's a 2-pole, pluggable NH00 unit rated 160 A with a DC23B 230 V switching category and a 100 kA breaking capacity at DC 230 V — that's the fault-clearing figure for a mill's DC bus or a large battery bank, not just a motor branch. The manual operating handle and integrated EFM 25 fuse monitoring tell you this was designed for a panel where a blown fuse needs to flag back to the PLC without a tech walking the line. The DC23B duty rating means it's tested for switching DC loads with a time constant up to 15 ms, typical for DC motor fields, solenoid banks, or battery supplies. The NH00 fuse size is the common European low-voltage HRC format; pluggable design means the fuse carrier slides out without tools for quick replacement. Fuse monitoring via the EFM 25 module sends a signal when a fuse blows — critical for a remote MCC or a conveyor line where downtime is measured in tons per hour lost. ## Panel integration In-line design mounts directly into the busbar or cable run. The manual operating handle protrudes through the enclosure door. The Group Code P360 and Product Group 5862 are Siemens internal cataloguing fields used for BOM system cross-references and spare-parts lookup. If your ERP or CMMS filters by these codes, this is the match for the 3NJ63 DC switch disconnector line.","metaTitle":"Siemens 3NJ6302-3AE0.-....
