AC SPD

Original price was: ₱1,000.00.Current price is: ₱800.00.

These specialized AC Surge Protective Devices (SPDs) deliver critical, industrial-grade defense against catastrophic voltage spikes, grid transients, and lightning surges occurring on the alternating current side of photovoltaic systems. Installed as a safety gate between the solar inverter’s output and the main property distribution panel, these robust surge arrestors instantly clamp dangerous transient voltages. This nanosecond-fast redirection routes destructive electrical energy safely away into the earth channel, keeping your sensitive household appliances and expensive inverter circuits fully intact.

Engineered with convenience and system uptime in mind, these AC SPDs feature a compact, 35mm DIN-rail mountable layout with user-friendly plug-in cartridges that permit rapid, tool-free replacement without disturbing primary system wiring. Complete with clear, color-coded mechanical fault flags for effortless health monitoring and integrated thermal disconnectors to eliminate fire risks, they provide an indispensable layer of code-compliant safety for any modern renewable energy electrical 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.
