When 10mm Changes the Game
Measuring just 10*38mm, the Holly HC10AR packs a 690V/3A punch that’s reshaping industrial control systems. Unlike bulky traditional relays, this micro giant enables 35% space reduction in circuit board designs according to field tests from Shenzhen’s smart meter manufacturers.
Smart Grid Guardians
During State Grid Corporation’s 2023 substation upgrade, 120,000 HC10AR units were deployed in protection relays. Their 0.0002% contact resistance drift over 10,000 operations helped achieve 99.992% system uptime – a new benchmark in China’s power infrastructure.
EV Charger Revolution
BYD’s latest DC fast chargers utilize HC10AR clusters to handle 500V-800V battery systems. Lab tests show 15% faster cutoff response compared to previous models, translating to 8-minute charge time reductions for 400km range recovery.
Beyond Spec Sheets
What engineers really appreciate? The dual arc suppression design that survived 72-hour salt spray tests at Qingdao’s coastal wind farms. “We’ve seen 30% fewer maintenance calls since switching to HC10AR,” reports site manager Zhang Wei.
With over 2 million units shipped since 2021, this tiny titan proves that in high-voltage control, good things do come in small packages.
