When 20A Meets 690V: The Silent Hero in Your Control Panel
Hidden behind industrial cabinets and smart devices, the Holly HC10AR relay operates like a precision Swiss watch. With its compact 10x38mm footprint, this 20A/690V powerhouse has become the go-to solution for engineers tackling space-constrained designs. Last year’s industry survey showed 73% of automation panel designers prioritize compact high-voltage components – and Holly delivers.
Real-World Superpowers: From Solar Farms to Smart Factories
At a Jiangsu photovoltaic plant, 2,800 HC10AR units manage DC arc fault detection across solar arrays, surviving 100+ temperature cycles annually. The secret? A unique silver alloy contact system that maintains <0.5mΩ contact resistance even after 100,000 operations. One maintenance engineer joked: 'These relays outlast our coffee machines!'
Smart Home’s Invisible Guardian
When a Shenzhen smart lock manufacturer needed failsafe 690V surge protection, they turned to HC10AR’s fast 3ms response. Now 500,000+ smart homes use this relay as their first line of defense. ‘It’s like having a miniature power bouncer,’ quipped their lead designer during CES 2023.
Why Engineers Keep Coming Back
- 5kV dielectric strength – survives more lightning strikes than a palm tree
- UL/CB certified – the electrician’s equivalent of a passport
- -40°C to 85°C operation – works from Siberia to Sahara
With 28% YoY growth in industrial relay demand, Holly’s HC10AR isn’t just a component – it’s insurance for your electrical ecosystem.
