Rack PDUs
Rack power arrives on pin & sleeve because it locks against pull-out, seals against the floor grille, and cannot be plugged into the wrong voltage. Two families do almost all of it: the 320P6W single-phase feed and the 9h blue five-wire whip.
| Poles | Hour | Voltage | Body colour |
|---|---|---|---|
| 2P+E (3 wire) | 4h | 100-130V | Yellow |
| 2P+E (3 wire) | 5h | 277V | Grey |
| 2P+E (3 wire) | 6h | 200-250V | Blue |
| 2P+E (3 wire) | 7h | 480V | Red |
| 2P+E (3 wire) | 8h | 550V DC | Black |
| 2P+E (3 wire) | 9h | 250V DC | Blue |
| Poles | Hour | Voltage | Body colour |
|---|---|---|---|
| 3P+N+E (5 wire) | 5h | 3ØY 347/600V | Black |
| 3P+N+E (5 wire) | 6h | 220/380-240/415V | Red |
| 3P+N+E (5 wire) | 7h | 3ØY 277/480V | Red |
| 3P+N+E (5 wire) | 9h | 3ØY 120/208V | Blue |
Two poles and earth, 200–250 V, 20 A North American / 16 A IEC, IP67. It is the plug on the cord that runs from an overhead busway tap or a wall receptacle to a rack PDU whose inlet is a C20 or C14, and on cords that go straight to a server's C19 or C13. We list these cords today in the 6h cell: 320P6W to C13, C15, C19 and C21, including the A-Lock connectors that hold in the equipment, and to NEMA 6-15R, 6-20R, L6-15R, L6-20R and L6-30R.
3ØY 120/208 V is the rack distribution voltage in most North American data centres: three phases at 120 V to neutral, 208 V between phases. On a five-wire body that is 9h, blue. A 30 A rack PDU takes a 530P9W; a 60 A one a 560P9W. These whips are built to order and the clock says so on those cells; ask and we quote with lead time.
Where the PDU needs only line-to-line 208 V, the neutral goes away and the body is four wire: 430P9W or 460P9W. Same hour, same colour, one fewer sleeve.
A 230/400 V rack in Europe or Asia takes the 6h red five-wire body at 16 or 32 A (the 20 and 30 A cells on our clock). The cable behind it is H07RN-F or a harmonised PVC cord to the local rules.
An L6-30P locks too, but it does not stop you plugging 208 V into a 120 V PDU, and it does not seal. Pin & sleeve does both, which is why the busway makers standardised on it.
The cords
Every 320P6W cord we stock, one row per length and connector, with stock and price.
