Eaton Cutler-Hammer 3457B16G01 Trim Lock

The Eaton Cutler-Hammer 3457B16G01 Trim Lock is a critical hardware component designed for securing the structural integrity of Pow-R-Line panelboards and load center interiors. Engineered as a direct replacement for WestingHouse and Cutler-Hammer trim assemblies, this lock mechanism ensures the flush or surface-mounted trim remains seated against the tub or box, maintaining the NEMA rating and interior safety barriers. This panelboard trim lock features a heavy-duty cylindrical design capable of withstanding industrial vibration and frequent access cycles without fatigue. For contractors performing a commercial panelboard maintenance or panel swap, using the specific 3457B16G01 part number ensures compatibility with the existing door latch cutouts, eliminating the need for field modifications or drilling. High-quality Eaton electrical hardware like this trim lock is essential for maintaining the UL listing of the enclosure while providing secure, keyed access to the branch circuit breakers and distribution sections.

• OEM Compatibility: Specifically designed for Eaton Cutler-Hammer and legacy WestingHouse trim assemblies to ensure a precise mechanical fit.
• Structural Integrity: Maintains the proper tension between the panel trim and the enclosure, preventing gapping and ensuring safety barriers remain intact.
• Industrial Strength: Constructed from high-strength alloys to resist stripping and wear during heavy-use cycles in commercial environments.
• Streamlined Installation: Designed for rapid field replacement, allowing technicians to restore enclosure security without modifying the existing metalwork.

Will this trim lock fit older WestingHouse Pow-R-Line panels?
Yes, the 3457B16G01 is the standard replacement lock for most legacy WestingHouse and current Eaton Cutler-Hammer panelboard trims that utilize a round-style door lock.

Does this lock facilitate the grounding requirements for the panel door?
While the electrical bond is primarily established by the hinges and bonding straps, this panelboard door lock provides the necessary mechanical closure to ensure the trim is properly seated against the grounded enclosure.

Is the key included with the 3457B16G01 assembly?
Typically, these units are supplied with the standard Eaton panel key, but it is recommended to verify local requirements if a specific master-keying system is used for the facility.
