Rittal DK 7856.090 PSM Plus Socket Module, 4 x Schuko CEE 7/3, 16 A Thermal Fuse, Non-Switchable, for PSM Busbar
Rittal DK 7856.090 — PSM Plus socket module with 4 Schuko sockets and 16 A thermal fuse
The Rittal DK 7856.090 is a PSM Plus socket module with four Schuko (type F, CEE 7/3) sockets and a built-in 16 A thermal fuse, rated 110–230 V AC / 16 A, that snaps onto a Rittal PSM busbar inside a server or network rack. Modules are added along the busbar without tools, even while the system is running.
The thermal fuse (Trimax 16 A) protects the four sockets of this module separately and can be reset after it trips. The 250 mm module is made of anodised aluminium with black PA6 GF30 socket inserts and connects to the busbar through a WAGO WINSTA MIDI connector.
What's in the Box
- 1 x Rittal DK 7856.090 PSM Plus socket module (4 x Schuko, thermal fuse)
- No busbar, cable or plug included
What It Means in Practice
- Add protected outlets exactly where equipment sits along the vertical busbar.
- The module's own 16 A thermal fuse isolates an overloaded group of four sockets without tripping the whole busbar feed.
- Modules can be inserted or removed while the busbar is live.
- After a trip, remove the cause of the overload and reset the fuse.
What Will Not Work
- Use without a Rittal PSM busbar — there is no cable or plug.
- Non-Rittal racks or PDUs without the PSM rail system.
- BS 1363 (UK/Cyprus) plugs — the sockets are Schuko.
- Switching individual sockets on and off — the module is non-switchable.
