Vertiv GL36N12-30-B-AC00 NEMA 12 Wall-Mount Rack Enclosure
Overview
The Vertiv GL36N12-30-B-AC00 is a NEMA 12 rated, gray wall-mount rack enclosure designed for industrial and commercial environments where airborne dust, dripping water, and light splashing are real concerns. Available in 12U, 19U, or 26U height configurations and in 24" or 30" depth options, this enclosure gives system integrators flexibility to right-size the cabinet for the equipment load without over-specifying floor space. The GL36N12-30-B-AC00 is the 19U, 30" deep variant in this family — the configuration most commonly deployed in mid-density network edge, building automation, and physical security headend closets. For a broader look at the Vertiv enclosure and power catalog, the full lineup covers a wide range of rack form factors.
Key Features
- NEMA 12 Protection: NEMA 12 certification means the enclosure resists dust ingress and dripping or splashing water — relevant in manufacturing floors, loading docks, utility rooms, and any space that doesn't qualify as a climate-controlled IT room. This is the enclosure to reach for when a standard open-frame rack would collect debris or corrode.
- 19U Usable Space (GL36N12-30-B-AC00 configuration): 19U of rack-standard mounting space accommodates a realistic mix of NVR appliances, PoE switches, patch panels, and UPS units in a single wall-mount footprint. The same family scales to 12U for lighter installs or 26U when the equipment list grows — useful when standardizing on a single enclosure platform across multiple sites.
- 30" Depth: The 30" depth accommodates deeper 1U/2U rack-mount appliances that a shallower 24" variant would not. If your NVR or server chassis exceeds 22" of body depth, this is the configuration to specify — the 24" option physically cannot close the door with full-depth equipment inside.
- Integrated Cooling Flexibility: The enclosure ships ready for multiple thermal management approaches. An integrated fan/filter assembly handles low-heat loads where ambient air exchange is sufficient. For sealed environments where outside air is unacceptable (dusty production floors, outdoor-adjacent spaces), factory-installed air conditioning units are available at 1000 BTU, 1300 BTU, or 2200 BTU — the 2200 BTU tier is the appropriate choice for fully loaded NVR-plus-switch configurations running 24/7. Sites with evolving heat loads can order the base enclosure with the optional fan/filter or optional AC provision and add thermal management as the equipment populates.
- Gray Finish: The gray powder coat blends into standard utility and server room environments and is consistent across the wall-mount enclosure line, simplifying aesthetics in multi-cabinet installations.
- Wall-Mount Form Factor: Keeping the rack off the floor preserves aisle clearance in tight IDF closets and utility rooms, and reduces exposure to ground-level moisture and forklift traffic in warehouse or industrial settings.
Integration & Compatibility
The GL36N12-30-B-AC00 follows 19" EIA rack mounting standards, so any rail-mount equipment — NVRs, managed PoE switches, patch panels, power distribution units — installs without adapter hardware. The NEMA 12 rating aligns with common requirements in industrial control and building automation specifications. For physical security headend deployments, pairing this enclosure with a properly sized UPS inside the cabinet is the straightforward path to runtime protection without adding a separate floor-standing battery cabinet. When selecting an AC cooling option, verify the total heat dissipation (watts) of all installed equipment and convert to BTU/hr (multiply watts by 3.41) before specifying the 1000, 1300, or 2200 BTU tier.
Frequently Asked Questions
Q: What is the difference between the 24" and 30" depth options for this enclosure family?
A: The GL36N12-30-B-AC00 is the 30" deep variant. The 30" depth is needed when rack-mount equipment (NVRs, servers, larger UPS units) exceeds approximately 20–22" of chassis depth. The 24" depth suits shallower equipment such as patch panels, smaller switches, and compact appliances.
Q: What cooling options are available for this wall-mount enclosure?
A: The enclosure supports a fan/filter assembly for ambient air exchange, as well as factory-installed air conditioning units rated at 1000 BTU, 1300 BTU, or 2200 BTU. Optionally, it can be ordered ready to accept a fan/filter or AC unit added later. The GL36N12-30-B-AC00 itself is the gray 19U 30"-deep base configuration — specify the appropriate thermal option at time of order.
Q: Is this enclosure suitable for outdoor installations?
A: No. NEMA 12 is rated for indoor industrial environments with dust and non-corrosive liquid protection. Outdoor installations require NEMA 3R, NEMA 4, or NEMA 4X rated enclosures.
Q: What rack unit heights are available in this enclosure family?
A: The family is available in 12U (24" tall), 19U (36" tall), and 26U (48" tall) configurations. The GL36N12-30-B-AC00 is the 19U, 30"-deep variant.
Q: Does this enclosure ship with rack mounting rails included?
A: Package contents are not specified in the available product documentation. Contact the supplier prior to ordering to confirm whether adjustable rails, cage nuts, and mounting hardware are included or must be ordered separately.
The GL36N12-30-B-AC00 is the configuration I recommend most often for physical security headend closets in light industrial and warehouse environments — specifically because the 30" depth and NEMA 12 rating together solve two problems that a standard IT-room rack cannot: equipment depth and particulate ingress. The 19U footprint is the sweet spot for a mid-density install running an NVR, a managed PoE switch, a patch panel, and a rack UPS without spilling onto a second enclosure.
Technical Highlights:
- NEMA 12 Ingress Protection: Keeps dust and non-corrosive dripping water out — critical in environments like loading docks or light manufacturing floors where a standard open-rack or NEMA 1 enclosure would be inappropriate.
- 30" Depth: Accommodates full-depth 1U/2U rack appliances; a 24" enclosure physically cannot close the door on most NVR or server chassis, making this depth selection load-bearing rather than cosmetic.
- 2200 BTU AC Ceiling: The top-tier cooling option handles a fully loaded 19U cabinet running 24/7 video recording and switching loads — calculate your actual wattage (multiply by 3.41 to convert to BTU/hr) before specifying the 1000 or 1300 BTU tiers to avoid under-cooling a dense install.
Deployment Considerations:
- Wall-mount load capacity is not listed in the available specifications — confirm the mounting surface (stud spacing, drywall vs. concrete) can support the combined weight of the enclosure, equipment, and any UPS before installation.
- The NEMA 12 rating does not cover washdown or submersion; if the installation space receives hose-directed water (food processing, vehicle bays), step up to NEMA 4 or 4X.
This enclosure is the right call for a multi-camera NVR headend in a warehouse IDF closet or a building automation controller cabinet where dust management and equipment depth are non-negotiable constraints — not for a clean IT server room where an open-frame two-post rack would cost less and cool better.
