Square D Safety Switches Setting the standard for perfomance, quality, and reliability in today’s commercial and industrial applications First introduced in 1907, Square D™ by Schneider Electric™ safety switches have a long history of leadership in safety and performance. Since then, Schneider Electric has pioneered many innovations to help maximize the lifetime value of your safety switches. Safety switches play a crucial role in today’s commercial and industrial settings.
Performance Three Times the Life — Three Times the Value Designed for the Best Performance The performance of safety switches is important to the safe and profitable operation of many industrial settings. In addition, requirements from organizations such as OSHA have increased the use of safety switches in many commercial and industrial facilities. A key performance benefit of the Square D safety switch is its ability to break load. A locked motor can draw six to eight times motor full-load current.
Quality Safety First A Full Range of Accessories Square D safety switches are, above all else, built to increase safety. Visible blades are an important feature, and they must be visible in real-world conditions to visually verify that the downstream circuit is de-energized. Our switch blades are easily visible, even in the less-than-ideal lighting conditions where electrical equipment is often installed.
Reliability Cost-Saving Maintenance Advanced maintenance features extend switch life and reduce downtime, saving both labor and material costs. The Square D safety switch modular design allows the replacement of all interior worn or damaged components. Field-replaceable components such as interior line bases, load bases, and mechanisms are available. Moreover, handles and lock plates are also replaceable if they are damaged or vandalized.
