APC by Schneider Electric 0M-5350-011 5-Wire L21-20 11-Foot Standard Power Cord
Overview
The APC by Schneider Electric 0M-5350-011 is an 11-foot, 5-wire standard power cord with an L21-20 locking connector — a purpose-built input power cable for rack PDU deployments where a secure, twist-lock connection matters. APC's APC by Schneider Electric power accessories are a common fixture in data center and server room builds, and this cord fits that same install pattern: connecting power distribution units to the upstream power source cleanly and without improvised adapters.
The 11-foot cord length gives you enough slack to route from a floor-mount or rack-mount PDU up to an overhead busway or wall-mounted panel without straining the connection — a practical advantage over shorter cords that force awkward routing in deep racks. The NEMA L21-20 locking plug means once it's seated, vibration or accidental contact won't pull it loose, which matters in environments with dense cable populations or physical activity nearby.
Per the product documentation, this cord is compatible with APC's AP8000 series Rack Power Distribution Units, which use a cord retention method designed around locking IEC power cords. If you're provisioning or replacing input power cables for an AP8000-series rack PDU, the 0M-5350-011 (sometimes searched as 0M 5350 011) is the correct replacement or spare to specify.
For rack power planning, review the rack PDU category to confirm the upstream distribution unit before ordering this cord. The L21-20 connector is a 3-phase locking configuration — verify your panel or busway tap matches before finalizing the order, as L21-20 is not interchangeable with single-phase L5 or L6 variants.
Key Features
- 11-Foot Cord Length: Provides adequate routing slack for standard rack-to-panel or rack-to-busway runs — reduces the need for extension solutions that add failure points.
- NEMA L21-20 Locking Connector: Twist-lock engagement keeps the plug seated under vibration and in high-traffic environments; won't back out from incidental contact the way straight-blade connectors can.
- 5-Wire Construction: Supports 3-phase wiring with neutral and ground — appropriate for 3-phase PDU input applications where a 3-wire cord would leave you without neutral or ground paths.
- AP8000 Series Compatibility: Designed to pair with APC's AP8000 rack PDU line, which uses a patented cord retention system — this cord is built to engage that retention mechanism correctly.
Integration & Compatibility
This cord is identified as compatible with APC AP8000 series Rack PDUs. The L21-20 plug configuration is a 3-phase, 20A, 120/208V locking connector — confirm that your facility's panel or PDU tap matches this specification before ordering. No additional adapters or hardware are included based on available evidence.
For related power cords and accessories, verify the specific PDU model number to ensure the correct cord variant is selected, as APC offers multiple cord configurations across the same PDU family.
Frequently Asked Questions
Q: What connector type does the 0M-5350-011 use?
A: The 0M-5350-011 uses a NEMA L21-20 locking plug. This is a 3-phase locking configuration — verify your panel or PDU tap supports L21-20 before ordering.
Q: What is the cord length on the 0M-5350-011?
A: The cord is 11 feet (approximately 3.35 meters) long.
Q: Which APC PDUs is the 0M-5350-011 compatible with?
A: Per APC product documentation, this cord is compatible with the AP8000 series Rack Power Distribution Units, which feature a patented cord retention system designed for locking IEC power cords.
Q: How many wires does the 0M-5350-011 have?
A: It is a 5-wire cord, supporting 3-phase connections with neutral and ground conductors included.
Q: Is the 0M-5350-011 a replacement cord or does it come bundled with a PDU?
A: The 0M-5350-011 is sold as a standalone power cord — it is a replacement or spare input power cable, not bundled with a PDU.
The 0M-5350-011 is one of those components that gets overlooked until someone orders the wrong cord and the install stalls. The L21-20 locking plug is the detail that matters here — it's a 3-phase configuration, and it's not compatible with single-phase L5 or L6 panels. I see this cord misspecified regularly when integrators assume any 20A locking cord will fit an AP8000 PDU input.
Technical Highlights:
- L21-20 Locking Connector: Twist-lock engagement prevents accidental disconnection — critical on input cords where a pulled plug means a full PDU outage, not just a single outlet.
- 5-Wire, 11-Foot Run: The 5-wire construction carries 3-phase plus neutral and ground; the 11-foot length covers most overhead busway or wall-panel tap distances without a cord extender adding another potential failure point.
- AP8000 Series Fit: Built for APC's patented cord retention mechanism on AP8000 PDUs — the retention clip engages the cord body, so a cord that doesn't match the OD spec won't seat correctly in the retention bracket.
Deployment Considerations:
- Confirm your upstream panel tap is L21-20 (120/208V 3-phase) before ordering — this cord will not mate with L15-20, L16-20, or single-phase locking connectors regardless of ampacity match.
- Evidence does not include AWG gauge or jacket material — if your local electrical code requires a specific gauge for runs over a certain length, verify with APC's full datasheet before specifying this cord in a permitted installation.
Best fit for AP8000-series PDU replacements and spare-cord provisioning in 3-phase 208V data center racks — not a general-purpose power cord substitute.
