Nvent AL3A Non-locking Handle Latch Nema 12

Product Description

The NVENT AL3A is a non-locking handle latch designed for use with NEMA 12 rated electrical enclosures. This hardware component provides a secure closure mechanism for enclosure doors without requiring a key or lock cylinder, making it well suited for applications where controlled but tool-free access is needed. At 0.70 pounds, it is a compact, lightweight fitting intended for installation by licensed electricians or panel builders working on industrial or commercial enclosure assemblies. The latch is the type of component that sees regular use in control panel fabrication and field enclosure maintenance.

This latch is appropriate for NEMA 12 enclosures, which are rated for indoor use in environments with dust, dirt, and dripping non-corrosive liquids. Typical applications include industrial control panels, motor control centers, and electrical distribution enclosures found in manufacturing, mechanical rooms, and similar commercial settings. It is installed during initial panel fabrication or as a replacement when an existing latch mechanism wears or fails.

Key Features

• Non-locking design allows tool-free door access without a key or lock cylinder
• Rated for NEMA 12 enclosure applications — suitable for dusty and drip-resistant indoor environments

Compatibility

Designed as an OEM-style replacement handle latch for NEMA 12 rated electrical enclosures. Verify door cutout dimensions and mounting hole pattern against existing hardware before installation.

Installation Notes

Installation should be performed by a qualified electrician or panel builder. De-energize the enclosure and follow all applicable NEC guidelines before opening or servicing any panel. Ensure the door panel cutout matches the latch footprint and that mounting hardware is tightened securely to maintain the enclosure integrity rating.
