Why Engineers Specify ArcShield

1
100,000-Cycle Endurance Testing

Every circuit breaker undergoes mechanical endurance testing beyond IEC requirements before shipment. Our field failure rate is consistently below 0.05%.

2
Dual IEC & UL Certification

Products tested and certified to both IEC 60947 and UL 489 standards simultaneously — eliminating dual-sourcing for global projects.

3
Arc Flash Energy Limitation

Integrated arc energy limitation technology reduces incident energy below 1.2 cal/cm² in standard configurations, enabling PPE Level 1 work practices.

4
RoHS & ISO 14001 Compliant

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.

Trusted by Engineers Worldwide

"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."


David R. Chen
Chief Electrical Engineer, Pacific Industrial Systems

"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."


Maria L. Hoffmann
Procurement Director, EuroPower Distribution GmbH

"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."


James T. Okonkwo
Plant Engineering Manager, Continental Packaging Ltd.

Frequently Asked Questions

Molded Case Circuit Breakers (MCCBs) are designed for higher current ratings (typically 16A to 6300A) and higher breaking capacities (up to 100kA), making them suitable for main distribution and feeder protection. Miniature Circuit Breakers (MCBs) handle lower currents (up to 125A) with breaking capacities of 6kA to 10kA, ideal for branch circuit protection. ArcShield manufactures both ranges to IEC 60947 and IEC 60898 standards respectively.

Our full product range is certified to IEC 60947 (international), UL 489 and CSA C22.2 (North America), and holds CE Marking under the Low Voltage Directive 2014/35/EU. For China market access, our products carry CCC (3C) certification. All products are RoHS compliant, and our manufacturing facilities are ISO 9001 and ISO 14001 certified.

Arc flash incidents release extreme thermal energy that can cause severe burns and ignite flammable materials. ArcShield circuit breakers incorporate arc energy limitation technology that reduces incident energy levels below 1.2 cal/cm² in standard configurations. This means maintenance personnel can work with PPE Level 1 protection instead of heavy arc flash suits, improving safety and productivity simultaneously.

Yes. Our modular platform supports thousands of configuration combinations — including special rated voltages (up to 690V), non-standard trip settings, specific auxiliary contact arrangements, and motor-operated mechanisms. Custom configurations are type-tested and can be delivered in 8 to 12 weeks from design freeze. Contact our applications engineering team for a specification review.

Standard MCB and MCCB models are stocked at our regional distribution hubs and typically ship within 5 business days. For high-volume project orders, our logistics team coordinates consolidated shipments to meet your project timeline. Emergency stock programs are available for critical infrastructure replacements — contact our global supply desk for expedited delivery.
