Feature:1. MULTI FUNCTIONS: With photovoltaic array input, primary combination, fast circuit disconnection, lightning protection, anti reverse connection, overload protection and more functions.2. MAIN USAGE: Protect PV solar panels and inverters, reduce length of connecting cables, optimize system instructions, and could increase output power of PV power generation system.3. INTIMATE DESIGN: The installation and wiring is simple. Transparent cover can check the status of main switch and lightning arrester. IP66 waterproof flame retardant material is more reliable.4. SAFETY DEVICE: 63A air circuit breaker provides short circuit fault protection and control combiner box output. Lightning arrester provides lightning protection. 12 pcs separate 10A rated fuses for overload protection.5. USED FOR: PV grid or off grid solar power generation system, make your solar panel system work reliably and safely, a perfect equipment for outdoor installation and use.Specification:Item Type: Photovoltaic Combiner BoxMaterial: Polycarbonate, ABS, stainless steelInput: 6 stringsOutput: 1 stringMaximum Voltage: 500VMaximum Short Circuit Current (isc) of Each Input: 10A (replaceable)Maximum Current Input: 63AProtection Grade: IP66Impact Resistance: IK10Size: Approx. 410x280x140mm/16.1x11x5.5in (excluding protruding parts)Cable Inlet: PG09 2.5-16mm, connector 2.5-6mmOutput Current Sealing Ring: PG21 2.5-16mm, connector 2.5-6mmDC Disconnector: LQB1 63Z/63A 2PRated Insulation Voltage (Ui): 500VRated Current (Le): 63ADC Arrester: LD 40Maximum Working Voltage (Ucpv): 600VMaximum Discharge Current: 40KADC Fuse Holder: LQPV 1000VDCRated Working Voltage: 500VFuse: Approx. 10x38mm/0.4x1.5in 10A.Package List:1 xPhotovoltaic Combiner Box1 x Manual1 x Grounding Wire1 x Solar Special Wrench4 x Screw4 x Screw Anchor4 x Connector (2 x Male, 2 x Female)4 x Core
