ABB 2CCP842001R1259 is a Miniature Circuit Breaker (MCB) designed specifically for photovoltaic (PV) or solar DC applications. It features screw-clamp connections for secure installation and is rated for a current of 25A with a DC voltage rating of 800Vdc. This MCB has a net height of 8 kV and a rated impulse voltage (Uimp) of 54 mm, indicating its robustness against voltage spikes. It is a 2-pole (2P) device, ensuring it can interrupt both poles simultaneously in the event of a fault. The net width is 82.5 mm, making it suitable for standard DIN rail mounting, which is the control voltage (AC) specification. It is designed for 10,000 operations, highlighting its durability and longevity in solar energy applications. The rated insulation voltage (Ui) is 1500 V, further emphasizing its capability to handle high-voltage environments safely.
