IP65 Enclosure: Made of PC+ABS material, it has high impact resistance, high heat resistance, good dimensional stability, excellent flame retardancy, acid and alkali resistance, solvent resistance, and UV resistance. DC Miniature Circuit Breaker: built-in arc squelching magnet which enables the high arc extinguisher,flame-retardant enclosure, silver contacts, and sufficient pure copper coils to ensure its high quality. Solar connectors: made of red copper which has higher conductivity,the solar extension cable with a length of no more than 30cm and two pairs of solar connectors to achieve faster and safer wiring and plug and play Multiple protection: isolation, short circuit protection(48V-1000V), and overload protection,C-curve trip,it can be used for DC12V-1000V DC systems. The breaker box is suitable for photovoltaic solar panel grid-connected system and solar off-grid system solar power system, photovoltaic array, RV solar. Non-polarized circuit breakers do not require polarity distinction and can be connected in either direction, simplifying installation and reducing wiring errors. They are particularly suitable for applications where polarity may reverse, such as:Reversible motors,Battery charge/discharge switching.Bidirectional current protection including:EV charging/discharging circuits,Solar power systems (where battery current direction reverses),Industrial reversible drive systems. miniature circuit breaker is used for DC circuit. It is suitable for circuit equipment with voltages of DC12~1000V, and is often used to protect the circuit between the solar panel and Inverter. This product is composed of IP65 waterproof box, cable gland and circuit breaker. It has the function of IP65 waterproof and dustproof, and is safer to use. It is suitable for indoor, outdoor eaves, distribution board, under the solar panel, warehouse, etc. place. ------ Specifications Model: HT3 DZ47Z 60A Rated Operating Voltage : DC1000V Poles: 2P Rated Current: 60A Working Frequency: 50/60Hz Breaking Capacity: 6kA Ics=Icu Trip Curve: C Mechanical Life: 10,000 times Electrical Life: 4,000 times Installation Method: 35MM DIN Rail Standard: IEC60898 / GB10936 Operating Temperature: -30℃ to +80℃ Operating Altitude: 2000 Meter
