Server Technology C3B36RL-5CJE0AT2 0U 36-Outlet Ramlock HDO PDU

Overview

The Server Technology C3B36RL-5CJE0AT2 is a 0U vertical rack power distribution unit built for high-density data center cabinets that need three-phase 415V power split across 36 outlets without eating into usable rack space. This is a Basic (non-monitored) PDU in Server Technology's Ramlock HDO family, terminated with a NEMA L22-30P input plug rated for 30A input current (24A continuous rated) — enough to feed a fully loaded server or network rack without derating headaches. If you're standardizing a colocation footprint or refreshing a row of racks, the C3B36RL-5CJE0AT2 is a straightforward, monitoring-free option for cabinets where you're tracking load at the panel or upstream PDU level instead of per-strip.

Key Features

• 17.3kW Input Power Capacity: at 415V three-phase, this PDU supports dense GPU and blade server deployments where a single-phase strip would run out of headroom fast. Confirm your rack's actual draw against this ceiling before provisioning — it's the hard limit for the whole strip.
• 18x C13 Outlets Rated ≤12A @ 240V: covers standard server power supplies, switches, and most 1U/2U equipment without needing adapters. Twelve amps per outlet at 240V gives you real headroom for redundant PSU configurations.
• 18x Cx (C13/C19) Outlets Rated ≤16A @ 240V: the higher-rated outlet bank handles blade chassis and high-draw compute nodes that would trip a standard C13 circuit. Having both outlet classes on one strip means you don't need a second PDU for mixed-load racks.
• 36 Total Outlets on a 70-inch 0U Strip: at just 2.2in x 2.5in in cross-section, this mounts flush in the vertical rack channel and adds zero usable rack unit space — critical when every U in the cabinet is already spoken for.
• NEMA L22-30P Input Plug, 30A/24A Rated: a locking three-phase plug that won't walk out of the receptacle under vibration or cable strain — a real consideration in cabinets with heavy cable management pulling on the whip.
• Branch Circuit Breaker Protection ≤16A: each outlet branch is individually protected, so a fault or overload on one server doesn't take down the whole strip. Breakers are UL 489 and CSA C22.2 No. 5 compliant, and IEC/EN 60947-2 compliant for mixed-region deployments.
• 10 kAIC Interrupt Rating (North America): the breakers are rated to safely interrupt fault currents up to 10,000 amps, which matters in data centers where upstream fault current can be substantial — an underrated breaker is a fire risk, not just a nuisance trip.
• Unloaded Power Draw Under 10W: the PDU itself sips negligible power when idle, so it doesn't meaningfully add to your rack's cooling load or PUE calculations.
• Operating Range 0°C to 60°C / 8-90%RH: rated for standard data center environments plus hot-aisle containment scenarios that run warmer than typical 22°C setpoints — useful if you're running elevated-temperature ASHRAE profiles to cut cooling costs.
• 6,500ft/2km Operating Elevation: covers the overwhelming majority of North American data center sites, including higher-altitude facilities in mountain-region colocation markets.
• UL 62368-1 / CSA C22.2 No. 62368-1 Certified: audio/video and IT equipment safety certification for both US and Canadian deployments, relevant for facilities that require dual-market compliance documentation.

Integration & Compatibility

The C3B36RL-5CJE0AT2 (often searched as C3B36RL 5CJE0AT2) is a Basic PDU — it distributes power but does not include outlet-level or strip-level monitoring. If your operations team needs remote load visibility or per-outlet switching, look at monitored or switched variants in the same Ramlock HDO family rather than pairing this strip with add-on metering hardware. Because it terminates in a NEMA L22-30P plug, confirm your upstream panel or floor PDU has a matching L22-30R receptacle before ordering — three-phase locking connectors are not interchangeable across NEMA types. Pair this strip with properly rated three-phase upstream distribution and verify your rack's total connected load stays under the 17.3kW capacity, factoring in redundant PSU draw on server and network gear.

Frequently Asked Questions

Q: What input voltage and plug does the C3B36RL-5CJE0AT2 use?

A: It runs on 415V three-phase power at 50/60 Hz and terminates in a NEMA L22-30P locking plug rated for 30A input (24A continuous rated).

Q: How many outlets does the C3B36RL-5CJE0AT2 have and what are they rated for?

A: It has 36 total outlets: 18x C13 outlets rated up to 12A @ 240V and 18x Cx (C13/C19) outlets rated up to 16A @ 240V.

Q: Does the C3B36RL-5CJE0AT2 include outlet monitoring?

A: No. This is a Basic 0U PDU without outlet-level or strip-level monitoring. For load visibility, look at a monitored or switched model in the same Ramlock HDO family.

Q: What's the maximum power capacity of the C3B36RL-5CJE0AT2?

A: 17.3kW at 415V input, with individual branch circuits protected by breakers rated up to 16A each.

Q: What are the operating temperature and humidity limits?

A: Operating range is 0°C to 60°C and 8%RH to 90%RH, at elevations up to 6,500ft/2km.

Q: What certifications does the C3B36RL-5CJE0AT2 carry?

A: UL 62368-1 and CSA C22.2 No. 62368-1 safety certification, with branch circuit protection compliant to UL 489, CSA C22.2 No. 5, and IEC/EN 60947-2.

James Everett

What stands out on the C3B36RL-5CJE0AT2 is the 17.3kW capacity on a 415V three-phase input — that's a lot of headroom packed into a 0U form factor, and it tells you this strip is meant for dense compute racks, not a lightly loaded network closet.

Technical Highlights:

• 36-Outlet Mixed Configuration: 18x C13 outlets at ≤12A/240V plus 18x Cx outlets at ≤16A/240V lets you mix standard server PSUs with higher-draw blade chassis on a single strip instead of running two separate PDUs.
• NEMA L22-30P Locking Input: rated for 30A input (24A continuous), this plug design keeps the connection secure in racks with heavy cable churn — no accidental disconnects from a snagged cable.
• 10 kAIC Interrupt Rating: the branch breakers are rated to safely clear fault currents up to 10,000A, which is the kind of fault current you actually see on upstream three-phase data center circuits, not a token spec.

Deployment Considerations:

• This is a Basic unit — no SNMP, no outlet metering, no remote switching. If your monitoring strategy depends on strip-level telemetry, this isn't the model; check the monitored or switched variants in the Ramlock HDO line instead.
• Confirm the upstream receptacle matches the NEMA L22-30P plug before the unit ships to site — three-phase locking connectors aren't interchangeable, and a mismatch means a return trip or a field-terminated adapter nobody wants to inspect later.

This is the right call for a colocation or enterprise data center row standardizing on 0U three-phase distribution with centralized monitoring elsewhere in the power chain — C3B36RL-5CJE0AT2 fits cabinets where rack space is at a premium and 36 outlets need to be split cleanly between standard and high-draw equipment.
