AC PV Isolating Switch

Our AC PV Isolating Switch (AC Main Isolator) is a high-performance, IP66-rated power disconnect solution designed for safety and durability in solar PV systems, industrial equipment, and outdoor applications. This rotary isolator provides a visible physical break in the circuit, ensuring safe maintenance and preventing accidental power-on.

Built with a heavy-duty yellow plastic enclosure and a bright red rotary handle, it offers clear visual indication and prevents unauthorized operation. The IP66 waterproof and dustproof rating means it can withstand harsh outdoor conditions, including rain, dust, and high-pressure water jets, making it ideal for solar installations, construction sites, RVs, and marine use.

Certified with CE for safety compliance, this AC isolator switch meets international standards for electrical safety. It features a long mechanical life (over 10,000 cycles) and electrical life (over 5,000 full-load operations), ensuring reliable performance even in demanding environments. Easy to install with four mounting holes, it is the perfect choice for safe power isolation in any AC 230V system.

Strong Point

• Bright red rotary handle with ON/OFF marking for clear operation
• CE certified for compliance with EU safety standards
• Durable construction with high mechanical and electrical life
• Visible physical break for safe maintenance and lockout/tagout (LOTO)

Usage environment:

This AC PV isolating switch is suitable for both indoor and outdoor electrical safety isolation applications, and can operate stably within an ambient temperature range of -25℃ to +60℃. With an IP66 high-grade dustproof and waterproof rating, it resists rain erosion, dust intrusion and high-pressure water jets, making it ideal for long-term use in open-air, humid and dusty harsh environments.

It is widely applied in grid-connected PV systems, industrial distribution boxes, outdoor electrical equipment, construction site temporary power supply, outdoor lighting and RV power systems. The operating environment should be free of corrosive gases, flammable and explosive media, and strong mechanical vibration to ensure long-term reliable performance.

• Our AC PV isolating switch features IP66 waterproof and dustproof construction, making it ideal for outdoor and harsh environments. It provides a safe visible disconnection point with lockable function to prevent misoperation, while its 100A 230V rating ensures stable performance and long service life.
• Easy to install and widely used in PV systems, industrial power and outdoor equipment, this switch comes with CE certification, high-quality flame-retardant housing and reliable performance for both residential and commercial applications.

Before installation, ensure the circuit is completely disconnected to avoid electric shock. Mount the AC PV isolating switch securely on a flat wall or distribution cabinet through the four reserved mounting holes, keeping the operating area clear and easy to access. Connect the incoming AC power wires to the input terminals and the load wires to the output terminals, then tighten all terminals firmly to avoid overheating. Close the terminal cover properly to maintain the IP66 waterproof and dustproof performance.

To operate, turn the red rotary knob clockwise to the "ON" position for power supply, and counterclockwise to "OFF" to disconnect the circuit completely. The switch provides a visible physical break for safe maintenance and can be locked in the OFF position to prevent accidental operation. Do not operate the switch under heavy load frequently, and keep the operating environment free of corrosive gas and strong vibration.
