ArcShield circuit breakers safeguard critical power infrastructure across six major industrial sectors worldwide.
Every circuit breaker undergoes mechanical endurance testing beyond IEC requirements before shipment. Our field failure rate is consistently below 0.05%.
Products tested and certified to both IEC 60947 and UL 489 standards simultaneously — eliminating dual-sourcing for global projects.
Integrated arc energy limitation technology reduces incident energy below 1.2 cal/cm² in standard configurations, enabling PPE Level 1 work practices.
All products meet RoHS and REACH requirements. Our manufacturing sites are ISO 14001 certified with a 35% reduction in CO₂ per unit over 5 years.
"We have been specifying ArcShield circuit breakers in our panel assemblies for over eight years. The consistent breaking capacity performance and fast documentation response have made them our go-to supplier for critical infrastructure projects."
"When we expanded our distribution into the European market, we needed a supplier who could provide CE-marked products with complete documentation on day one. ArcShield had every Declaration of Conformity and test report ready before we placed our first order."
"The technical support team at ArcShield diagnosed our arc flash coordination issue within two hours of our call and provided revised protection settings within 24 hours. That level of responsiveness is what keeps critical production lines running."
