APC by Schneider Electric APDU11451SW Advanced Switched 3-Phase Rack PDU
Overview
The APDU11451SW is a high-density, switched 3-phase rack PDU delivering 14.4KW at 208V — the right unit when you need per-outlet switching control across a fully loaded equipment rack and can't afford an unplanned reboot to cycle a hung device. Designed for vertical side-mount installation in standard server or network racks, this unit handles the power density demands of modern rack power distribution environments without requiring a dedicated power drop beyond the included 9.8 ft (3 m) cord with CS8365C plug.
If you're speccing power infrastructure for a high-density security operations center, network closet, or surveillance recording room, the APC by Schneider Electric switched PDU line gives you remote outlet-level control — critical when racks are in locked, remote, or hard-to-access locations.
Key Features
- 14.4KW / 14,400VA Load Capacity: Supports 50A at 208V 3-phase — enough headroom for fully loaded racks of NVRs, servers, or network gear without derate anxiety. Size your breaker panel accordingly; this unit draws the full 50A circuit.
- Switched PDU Type: Individual outlet switching means you can power-cycle a locked-up NVR or switch remotely without dispatching a technician. For multi-rack security deployments, this is the difference between a 2-minute remote fix and a 2-hour truck roll.
- 208V 3-Phase Input (50/60 Hz): Dual-frequency compatibility simplifies deployment in both domestic and international facilities. The 3-phase input balances load across legs — essential for avoiding neutral conductor overload in high-density racks.
- CS8365C Input Plug, 9.8 ft (3 m) Cord: The NEMA CS8365C locking plug mates with standard 3-phase 208V PDU receptacles common in US data centers. The 3-meter cord gives enough slack for typical in-rack overhead or underfloor cable routing without an extension.
- 42 Outlets: High outlet density supports fully populated 1U and 2U equipment without outlet contention — no need for secondary strip PDUs that add failure points and cable clutter.
- Vertical Side-Mount, 71.9 in (1826 mm) Form Factor: Mounts flush to the interior side rail of a standard 42U rack. Vertical orientation keeps the PDU out of the equipment mounting area and simplifies cable dressing to each outlet.
- IP44 Ingress Protection: Rated IP44 — protected against solid objects over 1mm and splash water from any direction. Appropriate for equipment rooms where occasional condensation or cleaning spray is a concern, though not for wet or outdoor environments.
- 24.7 lb (11.2 kg) Unit Weight: Plan for two-person installation during rack integration. At 71.9 inches and nearly 25 lbs, solo mounting is awkward and risks rail damage.
Integration & Compatibility
The APDU11451SW integrates with APC network management cards and is designed for use within APC EcoStruxure-enabled environments, enabling remote monitoring, outlet scheduling, and load reporting through a compatible NMC. Pair with a compatible APC UPS upstream for full power protection. Verify your facility's 3-phase 208V panel capacity and breaker sizing before installation — a 50A circuit requires an 80A-rated breaker per NEC 80% continuous load rule.
Frequently Asked Questions
Q: What input plug does the APDU11451SW use?
A: The APDU11451SW ships with a CS8365C locking plug on a 9.8 ft (3 m) input cord, designed for 3-phase 208V / 50A circuits common in US data centers and equipment rooms.
Q: How many outlets does the APDU11451SW provide?
A: The unit provides 42 outlets, supporting dense rack populations without secondary strip PDUs.
Q: Can the APDU11451SW be monitored remotely?
A: Yes — the switched PDU type supports remote outlet-level control. Full remote monitoring requires a compatible APC network management card installed in the PDU's management slot.
Q: What is the IP rating of the APDU11451SW?
A: The APDU11451SW is rated IP44 — protected against solid particles over 1mm and water splashing from any direction. It is not rated for outdoor or immersion environments.
Q: What rack form factor does the APDU11451SW fit?
A: The unit is 71.9 inches (1826 mm) long and mounts vertically on the side rail of a standard 42U equipment rack. Mounting position preference is listed as no preference, supporting either left or right rail installation.
Q: Is the APDU11451SW compatible with 60Hz and 50Hz power systems?
A: Yes. The input frequency range is 50/60 Hz, making it suitable for both North American and international 3-phase 208V installations.
The APDU11451SW is the unit I spec when a customer is building out a high-density security or network rack and needs outlet-level switching without walking the data center floor. The 14.4KW / 50A 3-phase capacity means you're not leaving power headroom on the table in a fully loaded 42U enclosure, and the switched PDU type buys you genuine operational value — remote power-cycling a hung NVR at 2am beats a truck roll by any measure.
Technical Highlights:
- 50A 3-Phase Input at 208V: 14,400VA total capacity keeps you well clear of the 80% NEC continuous-load limit at realistic rack densities — no phantom overload trips under normal surveillance or compute workloads.
- 42-Outlet Density: Enough positions to populate a full 42U rack with 1U devices at one-per-outlet without outlet-sharing daisy chains that complicate troubleshooting.
- IP44 Rating: Splash-resistant construction tolerates the occasional condensation event in a poorly climate-controlled IDF closet — won't protect against a pipe burst, but handles the everyday damp conditions some equipment rooms accumulate.
Deployment Considerations:
- At 71.9 inches and 24.7 lbs, this is a two-person rack install — have a second set of hands before you attempt side-rail mounting, especially in a populated rack with limited maneuvering room.
- The CS8365C plug requires a matching 3-phase 208V / 50A receptacle at the panel. Confirm your facility's receptacle type before ordering — this is not a field-modifiable plug, and adapters introduce a failure point in a power-critical path.
The APDU11451SW is the right fit for security operations centers, surveillance recording rooms, and enterprise network closets where remote outlet control eliminates on-site intervention for routine power-cycle events — particularly in multi-site deployments where dispatching staff to a remote rack is expensive.
