Vertiv NEMA 12K WM 12UX24X30 Gray - GL24N12-30-B-AC00

Vertiv GL24N12-30-B-AC00 NEMA 12 Wall-Mount Enclosure 12U 24x30

Overview

The Vertiv GL24N12-30-B-AC00 is a NEMA Type 12 wall-mount enclosure designed for housing network, security, and control equipment in environments where protection from dust and dripping non-corrosive liquids is required. Built in a 12U form factor with a 24-inch width and 30-inch depth, this gray steel cabinet fits infrastructure deployments where floor space is at a premium — wall mounting keeps the footprint off the data center or IDF room floor entirely. The GL24N12-30-B-AC00 (often searched as GL24N12 30 B AC00) ships as part of Vertiv's GE wall-mount enclosure line, targeting light industrial, manufacturing, and commercial building infrastructure installations.

Key Features

• 12U Usable Height at 24" Width: The 12U rack space in a 24-inch-wide cabinet suits compact equipment deployments — enough room for a small PoE switch, patch panel, and a UPS module without requiring a full-depth floor cabinet. If your IDF closet wall is the only available mounting surface, 12U gets you functional without wasted vertical space.
• 30-Inch Cabinet Depth: The 30-inch depth accommodates most 1U and 2U rack-mount equipment including mid-depth network switches and security appliances. Shallower 24-inch depth variants exist in the family — the 30-inch option is the right call when you're housing equipment longer than approximately 22 inches including cable dressing.
• NEMA 12 Rating: NEMA 12 provides protection against circulating dust, lint, fibers, and dripping or splashing non-corrosive liquids. This makes the enclosure appropriate for light manufacturing floors, utility rooms, or mechanical spaces — environments where an open-frame rack would accumulate contamination that degrades hardware reliability over time.
• Flexible Thermal Management: The enclosure supports fan/filter assemblies, optional 1000 BTU, 1300 BTU, or 2200 BTU air conditioning units, or a clear (unobstructed airflow) configuration. Matching the thermal solution to actual equipment heat load matters: a lightly loaded patch-only cabinet runs fine on passive fan/filter; a fully populated switch and server cabinet in a warm utility room will need the 2200 BTU AC option to maintain equipment within operating temperature limits.
• AC-Accessory Ready: The "Accepts Optional AC" designation means the cabinet ships with the structural provisions (knockout or pre-cut) to accept Vertiv-compatible air conditioning units without field modification. Retrofitting thermal management after installation is practical — you're not locked into a thermal decision at purchase time.
• Gray Powder-Coat Finish: The standard gray finish matches most industrial and commercial infrastructure environments and resists surface corrosion in the non-washdown light-industrial environments NEMA 12 is rated for.

Integration & Compatibility

The GL24N12-30-B-AC00 is designed to accept standard 19-inch rack-mount equipment. The 30-inch cabinet depth provides adequate clearance for mid-depth switches, security NVRs, access control panels, and power distribution units common in security and building automation infrastructure. Thermal accessories — fan/filter kits and AC units — are sourced from the Vertiv enclosure accessories line. When planning a wall-mount enclosure installation, confirm wall stud spacing and load rating against the populated cabinet weight; consult the enclosure selection guide for mounting hardware requirements. Pair with a rack-mount PDU and appropriate PoE switch for a complete infrastructure deployment.

Frequently Asked Questions

Q: What rack unit capacity does the GL24N12-30-B-AC00 provide?

A: The GL24N12-30-B-AC00 provides 12U of usable rack space in a 24-inch-wide, 30-inch-deep wall-mount cabinet configuration.

Q: What NEMA rating does this enclosure carry, and what does that mean for my installation environment?

A: This enclosure carries a NEMA 12 rating, which provides protection against circulating dust, lint, fibers, and dripping or splashing non-corrosive liquids. It is appropriate for light manufacturing floors, utility rooms, and mechanical spaces, but is not rated for washdown or outdoor use.

Q: Can I add air conditioning to the GL24N12-30-B-AC00 after installation?

A: Yes. The enclosure is designed to accept optional AC units — the cabinet includes the structural provisions for 1000 BTU, 1300 BTU, or 2200 BTU Vertiv air conditioning accessories. You are not required to specify the thermal option at the time of purchase.

Q: What is the depth of this enclosure, and will it fit standard rack-mount equipment?

A: The GL24N12-30-B-AC00 has a 30-inch cabinet depth, which accommodates most standard 1U and 2U rack-mount equipment including mid-depth network switches, NVRs, and security appliances up to approximately 22–26 inches in equipment length depending on cable management.

Q: Is this enclosure available with different depth or height options?

A: The GL24N12-30-B-AC00 is the 12U / 30-inch depth configuration. The Vertiv GE wall-mount enclosure family includes 19U and 26U height options as well as 24-inch depth variants — specify the model number matching your U-count and depth requirement.

Jerry Tildsen

The GL24N12-30-B-AC00 is the enclosure I specify when a project calls for a hardened wall-mount solution in a space that sees real-world contamination — a manufacturing floor IDF, a utility room, or a mechanical chase where an open-frame rack would turn into a dust collector inside six months. The NEMA 12 rating is the deciding factor: it keeps circulating particulates and incidental liquid drips off your switching and security equipment without stepping up to a full NEMA 4 sealed enclosure.

Technical Highlights:

• 12U / 30-inch depth combination: Hits the sweet spot for IDF wall-mount deployments — enough U-space for a PoE switch, a patch panel, and a small UPS without requiring a floor footprint. The 30-inch depth clears most mid-depth switches comfortably.
• Scalable thermal options (1000–2200 BTU AC): The ability to retrofit AC up to 2200 BTU means you can right-size thermal management after load is confirmed rather than over-specifying at design time. In utility rooms without reliable HVAC, the 2200 BTU option is the safe ceiling for a fully populated 12U cabinet.
• Fan/filter baseline: The fan/filter configuration handles light to moderate heat loads at lower cost and with simpler maintenance than a compressor-based AC unit — correct for a patch-and-switch cabinet with no active servers.

Deployment Considerations:

• NEMA 12 is not rated for washdown environments or outdoor exposure — if the installation sees hose-down cleaning or is in an unconditioned exterior space, you need NEMA 4 or 4X. Confirm the environment classification before specifying.
• Wall mounting a populated 12U enclosure requires verified structural backing — confirm stud spacing and load capacity before installation. A fully loaded cabinet with an AC unit can exceed 100 lbs; drywall anchors alone are not adequate.

This enclosure is the right call for light-industrial IDF closets, manufacturing floor network nodes, and building automation control points where NEMA 12 protection is the minimum spec and thermal flexibility needs to be preserved for future load growth.
