When Machines Need a Trusted Switch
In the humming heart of industrial control panels, a green-and-silver component works tirelessly – meet the Holly HC10AR relay. Unlike flashy IoT gadgets, this 500V/3A electromechanical workhorse solves real-world problems: A Shenzhen-based EV charger manufacturer reduced warranty claims by 18% after adopting HC10AR relays in their charging pile control modules last year.
Three Strengths That Redefine Reliability
1. Arc-Busting Contacts: With silver-nickel alloy contacts (12% harder than standard silver-cadmium), HC10AR handles 200,000+ operations at full 3A load – crucial for automated packaging lines running 24/7.
2. Temperature Warrior: Maintains stable performance from -40°C to +85°C, proven during -2022 winter trials in Harbin’s outdoor power distribution systems.
3. Space-Smart Design: Its 15.8mm width fits control board layouts where every millimeter counts, as Jiangsu elevator OEMs discovered when upgrading control cabinets.
Silent Partner in Green Energy
When a Zhejiang solar farm upgraded their combiner boxes, HC10AR’s 500V dielectric strength reduced unexpected downtime by 23% compared to previous relays. Maintenance chief Wang Lei notes: ‘These relays survive sandstorms and humidity that killed others in 6 months.’
‘In critical power switching, 0.05 seconds matters. HC10AR delivers consistent response time.’

From wind turbine pitch controls to semiconductor fab equipment, Holly’s engineering teams have refined HC10AR through 7 iterative versions since 2015. Next-gen prototypes with IoT monitoring are already in field testing.
