HV Fuse Holder Safety Disconnect - 400 A Base
Terms and Conditions
Orders Dispatched Within 24 hours - Excluding Weekends and Bank Holidays.
The panel mounting base for a 400 A fused service disconnect, rated 1000 V DC with an interlock and IP67 sealing. It mounts on the pack and the fused disconnect plug pulls out of it.
This is the fixed half of the point where a technician breaks the high voltage circuit by hand. It passes through the enclosure wall, carries the pack side connections behind it, and presents the socket the fused disconnect locks into.
The interlock runs through this half. A signal loop is complete only while the plug is fully home. Wired into your BMS or contactor control, it opens the contactors the moment the plug starts to move, so the power contacts never part under load. Leave it unconnected and you are breaking a 400 A circuit by hand.
Mount it where a person can reach it, and where the plug once removed cannot be casually replaced by someone who did not take it out.

Compatibility
Takes the 400 A fused disconnect, DLQ2-T400-G001, which carries the 600GH-400 fuse. You need both unless you are replacing one half of an existing pair.
The current capacity depends on the assembly, not on this half alone. The 300 to 400 A figure covers the range this base is used across; what your installation actually carries is set by the fuse, the terminals and the cable.
For EV traction packs, energy storage and industrial DC distribution.
