Product details

SENTRON 3NJ6314-1AC0 NH1 Fuse-Switch Disconnector

The 3NJ6314-1AC0.-....: The Siemens 3NJ6314-1AC0 is a 4-pole NH1 fuse-switch disconnector from the SENTRON 3NJ63 family, rated 250 A with an AC23B utilization category at 500 V. It carries a 55 kA breaking capacity at 500 V AC, which means it can safely interrupt fault currents up to that level on a 500 V line without upstream cascading — critical for coordinating with downstream fuses in a distribution panel.

AC23B duty covers switching of motor loads and other highly inductive loads — this is not a general-purpose resistive-load switch. The 250 A rating is the maximum continuous current in that duty; for resistive loads (AC1) the same unit will carry more, but the AC23B figure is the one that governs motor-circuit fit.

Frequently asked questions

What is the group code and product group for this part?

The group code is P360 and the product group is 5862. These are Siemens internal classification codes used for logistics and cross-referencing in their catalog systems.

Where can I buy the 3NJ6314-1AC0 and how is it quoted?

This part is sourced to order through independent distribution channels. Submit an RFQ for current pricing and availability — the C-class made-to-order status means each unit is built per order, so the quote will reflect the production lead time.
