CNLonQcom Solar Disconnect Switch 32A DC500V — T2 Surge Arrester, IP65 Weatherproof Breaker Box

The CNLonQcom Solar Disconnect Switch is a plug-and-play DC safety module that combines a 32A circuit breaker and T2 surge arrester inside an IP65 weatherproof enclosure for outdoor solar systems.

This compact, durable unit is designed to protect solar arrays, inverters and downstream equipment from overloads, short circuits and lightning-induced surges while making field wiring quick and straightforward. Built for rooftop and ground-mount installations, it integrates a removable surge module with visible replace indicator, a dual-direction wiring option, and photovoltaic connectors for fast connection.

How does this device protect my solar system from overloads and shorts?

The built-in 32A circuit breaker rated for DC 500V interrupts fault currents and limits damage from overload or short circuits. It uses a wiring-neutral design so installers can route conductors top-to-bottom or bottom-to-top depending on site constraints.

• 32 ampere trip rating for typical residential PV strings
• DC500V rating suitable for many string voltages
• Short-circuit and overload interruption for system safety
• Flexible top-in/bottom-out wiring orientation

What does the surge protector do and how will I know when it needs service?

The integrated T2 surge arrester diverts high-energy transients from lightning or switching events away from sensitive electronics. It features a removable surge module with a red indicator that shows when the protector needs replacement, allowing quick maintenance without disturbing the main breaker.

• 20kA/40kA rated clamping capability for transient suppression
• 6mm thick shielded storm chip increases robustness
• Removable module design enables fast swaps in the field
• Red visual indicator signals end-of-life for the surge component

Is the enclosure suitable for outdoor use and how will I monitor status?

The durable PC+ABS shell is UV-resistant, flame-retardant and rated IP65 to keep moisture and dust out of the electrical compartment. A transparent observation window provides visual access to the breaker and surge module so you can inspect operation without opening the enclosure.

• IP65 protection for rain and dust in outdoor locations
• UV-resistant materials for long-term sun exposure
• Transparent window to check status lights and breaker position
• Robust mechanical construction for rooftop or ground-mount use

How easy is installation and where can I use this unit?

The product ships with photovoltaic-style male and female connectors and is designed for plug-and-play connection to typical PV string cables. Its combination of breaker and surge protection makes it suitable for grid-tied and off-grid arrays, RV systems, residential installs and outdoor PV arrays.

• Photovoltaic connectors included for fast, reliable hookups
• Works with grid-connected or stand-alone solar systems
• Ideal for homes, RVs, small commercial arrays and remote sites
• Compact footprint saves mounting space on rails or walls

Who this is for: Installers, solar DIYers and property owners seeking a single, weatherproof safety module that combines DC-rated circuit protection with a field-serviceable surge arrester. If you need a compact, dependable way to isolate and protect a PV string—especially in outdoor or exposed locations—this unit streamlines wiring, inspection and surge maintenance without requiring separate components.
