ATO 63A DC Circuit Breaker - 250V, 1 Pole Optional, IP20 Protection for Solar PV/Battery Energy Storage/DC Charging Systems

Multiple Voltage & Pole Options：Choose from 250V (1 Pole), 500V (2 Pole), 750V (3 Pole), 1000V (4 Pole) to match different DC power system needs, with 1000V rated insulation voltage for stable performance. High Safety & Breaking Capacity：25 KA breaking capacity and 20 ms total break time quickly cut off abnormal currents; IP20 protection level and ≥50 mm flying arc distance prevent electric shock and arc hazards, meeting IEC60947-2x, IEC60947-K, GB14048.

R, GB14048.2 standards. Flexible Installation & Wiring：Fits IEC standard 35 mm track (fixed/insertion mounting); dual-function terminals (open type/lifting type) on top and bottom, optional busbar fixing; wiring terminal guidance avoids mis-wiring, supporting 1-25 mm² wire and 2-2.4 Nm screw tightening torque.

Dual Function & Wide Application：With isolation function, can be used as main switch; ideal for solar photovoltaic systems, battery energy storage systems, new energy vehicle DC charging systems, power transfer switches, and overload protection devices.

Stable Performance in Extreme Temperatures：Works normally in -25 ℃ ~ 50 ℃ ambient temperature, functional regardless of mounting angle, suitable for harsh working environments.
