These specialized AC Breakers provide essential, code-compliant overcurrent and short-circuit protection engineered to secure the alternating current side of your photovoltaic system. Acting as the critical safety bridge between your solar inverter’s output and the local utility grid or main distribution panel, these heavy-duty circuit breakers instantly trip to isolate faults. This fast-acting thermal-magnetic isolation safeguards your property’s electrical grid and protects advanced inverter electronics from devastating back-fed overcurrent spikes.

Crafted with a standardized, compact DIN-rail mounting profile, these AC circuit breakers integrate seamlessly into any existing consumer unit, main switchboard, or solar AC distribution enclosure. Featuring rugged, heat-resistant housings and erosion-resistant internal contacts, they provide exceptional electrical efficiency and long-term mechanical reliability under continuous heavy loads. By delivering reliable circuit isolation and immediate trip diagnostics, they ensure a safe, robust, and fully protected renewable energy infrastructure.

Description

Key Features:

  • Designed for Alternating Current (AC) Solar Integration: Engineered specifically to safely manage and isolate the alternating current output line extending from solar grid-tied or hybrid inverters to the main property distribution panel.
  • Dual-Action Thermal-Magnetic Protection: Combines a thermal element for long-term overload protection with a magnetic mechanism for instantaneous short-circuit trip responses, safeguarding critical building infrastructure.
  • High Interrupting Breaking Capacity: Rated to withstand and successfully extinguish high prospective fault currents, protecting downstream household circuitry and expensive inverter internal components.
  • Standardized DIN-Rail Mount Architecture: Features a universal, compact clip-on profile designed for rapid, neat integration inside consumer units, main switchboards, and specialized AC combiner enclosures.
  • Visual Trip Status Indication: Equipped with an intuitive, front-facing flag indicator or clear toggle interface to allow maintenance personnel to instantly diagnose a tripped circuit at a glance.
  • Heavy-Duty Contact Material Construction: Built with premium, erosion-resistant silver alloy contacts to ensure stable electrical conductivity, low resistance, and cool operational temperatures over thousands of switching cycles.
  • Complies with International Electrical Codes: Thoroughly certified to rigorous global standards (such as IEC/EN 60947-2 or UL 489), ensuring safe, code-compliant commercial and residential grid-interconnection setups.

Applications:

  • Main AC Isolation Panels for Residential and Commercial Solar Inverters
  • Grid-Tied and Hybrid Photovoltaic Sub-Distribution Boards
  • AC Combiner Boxes aggregating multiple string inverter outputs
  • Emergency Power Supply (EPS) and Critical Load Backup Switching circuits
  • General Building Electrical Overcurrent Infrastructure protection

Protect your solar investment with these high-performance AC Breakers, ensuring reliable operation and enhanced protection for your photovoltaic power system.
