AC vs DC Safety Switches: Power Protection Built for Purpose

Why It’s Not Just “A Switch Is a Switch” 

You wouldn’t use the same cable for everything, so why use the same disconnect? 

AC and DC circuits behave very differently, especially when switching under load. That’s why GARO’s safety switches aren’t one-size-fits-all—they’re designed specifically for the kind of current they’ll be isolating. The result? Safer installs, fewer call-backs, and equipment that works exactly how and when it should. 

AC Safety Switches: Built for Everyday Toughness 

If you're dealing with traditional AC power—think HVAC systems, plant rooms, or lighting circuits—GARO's AC Safety Switches are your go-to. These aren’t just boxes with a handle; they’re IP65-rated workhorses designed for the real world. 

Key Benefits: 

• 4-pole switching from 20A to 100A at 400V AC 

• Fully interlocked design—you can’t turn it on while the cover’s off 

• Padlockable handle with 3 positions (On/Off/Padlocked) 

• Tough, weatherproof enclosures with corrosion-resistant screws 

• Sized just right, with DIN rail removal and variable knockouts for stress-free installs 

From new builds to retrofits, GARO safety switches ensure fast, compliant installations with zero compromise on safety or performance. 

 

DC Safety Switches: Made for Solar, Storage & EV 

Unlike AC, DC circuits maintain a constant flow of current—making arc suppression more critical. That’s why DC switching demands a tailored approach and why our DC Safety Switches are designed to deal with the unique demands of high-voltage solar arrays, EV chargers, and battery systems. 

 Key Features: 

• Handles up to 1500V DC safely 

• Designed to reduce arcing—a must for high-voltage disconnects 

• Same user-friendly layout as our AC switches—because consistency saves time 

• 3-position handle with lockout—so servicing is safer and clearer 

• IP65-rated, for installs where dust, weather, or corrosion are real concerns 

Whether you're wiring a solar farm, an EV hub, or a smart home battery setup, these switches have your back. 

So, AC or DC? Here’s the Quick Take: 

Feature	AC Safety Switches	DC Safety Switches
Voltage Rating	400 Volts 5.5 kW - 37 kW AC 23	Up to 1500V DC
Use Case	HVAC, lighting, industrial machinery	Solar PV, EV charging, battery storage
Arc Suppression	Standard AC-rated	Enhanced for DC switching
Enclosure Rating	IP65	IP65
