Setting the standard for perfomance, quality and reliability in today’s commercial and industrial applications
First introduced in 1907, Square D safety switches have a long history of leadership in safety and performance. Since then, we have pioneered many innovations to help maximize the lifetime value of our safety switches.
Safety switches play a crucial role in today’s commercial and industrial settings. They isolate power in daily activities and provide an effective way to interrupt power in an emergency. Two primary applications for safety switches are as a lockout on sight disconnect and as a circuit isolation device.

Square D offers breakers, switches, load centers, grounding kits and more.
