Legrand 1255L 30A 120V AC Single Pole Double Throw Wall Switch
A 30 A, 120 V AC single-pole double-throw wall switch with fork-key locking and 14–10 AWG side wiring
- Single-pole double-throw action gives two circuit paths from one switch
- 30 A rating at 120 V AC handles heavy-duty loads
- Locking fork-key style prevents unauthorised operation
- CSA certified 17949 and UL listed for code-compliant installs
- Accepts 14–10 AWG wire on side terminals for secure connections
Single-pole double-throw switch
The Legrand 1255L is a 30 A wall switch rated for 120 V AC circuits. Its single-pole double-throw action suits motor-control or lighting circuits that require momentary contact. The fork-key locking style prevents unauthorised operation in commercial or industrial settings.
Thermals noise and power draw
As a passive electromechanical device the switch generates no audible noise and draws no power of its own. Heat rise is limited to normal contact resistance when carrying up to 30 A within the 120 V AC rating. No active cooling or ventilation is required.
Bundled accessories and software
The unit ships as a standalone switch with no bundled accessories or software. Installation uses side wiring terminals that accept 14 AWG to 10 AWG conductors. Mounting holes are spaced 3.3 in centre-to-centre and the device carries CSA certification 17949 and UL listing.

Questions about this item
How do I wire the 1255L switch using the side terminals and which wire gauge range applies?
Strip 14 to 10 AWG solid or stranded copper wire, insert fully into each side terminal, and tighten the captive screws to the torque marked on the device; the common terminal is the fork-key locking position.
Which parts of the 1255L will wear out first and need replacement?
The spring-loaded momentary mechanism and the silver-alloy contacts are the service items; replace the entire switch when the return action feels soft or the contacts show pitting.
At what load does the 1255L hit its thermal limit during continuous operation?
The 30 A, 120 V AC rating is the continuous maximum; running at that level will bring the contacts to their design temperature first.
