DIHOOL DC Circuit Breaker, Non Polarized, 20 Amp, 2 Pole, 12V - 400V, AC DC Disconnect Switch Box Outdoor, Battery Cutoff Isolator, PV Array MCB

miniature circuit breaker is used for DC circuit. It is suitable for circuit equipment with voltages of AC DC400V, 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: HT2 DZ47X 20A Rated Operating Voltage : AC DC400V Poles: 2P Rated Current: 20A Working Frequency: 50/60Hz Breaking Capacity: 4kA Ics=Icu Trip Curve: B 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

• With IP65 waterproof breaker box,Suitable for outdoor installation, such as connecting solar energy, car charging posts, etc.the transparent cover also make it easy to check the status of the circuit breaker.
• Miniature circuit breaker has 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: the solar extension cable with a length about 30cm and two pairs of solar connectors to achieve faster and safer wiring and plug and play
• Multiple protection: isolation, short circuit protection(48V - 400V), and overload protection,C-curve trip,it can be used for 12V-400V DC or AC systems.
• The breaker box is suitable for photovoltaic solar panel array,Solar Charge Controller,Batteries,Power inverter,household lighting, small motor control
• 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.
