Specifications Installation: 35mm guide rail Operation mode: manual Tripping method: overcurrent release Protection type: overload, short circuit protection Packing List 1 * DC Miniature Circuit Breaker 32A Material: PC plastic + copper Application circuit: DC circuit Rated voltage: DC 1000V Rated current: 32A Breaking capacity: 6 (kA) Number of poles: 2P Mechanical life: 20000 times Tripping type: C-type Wiring capacity: 1.5-10mm² Working temperature: -35 ℃ -70 ℃ Wide Application Small in size and light in weight, the circuit breakers are suitable for DC systems such as solar energy, combiner boxes, photovoltaic systems, new energy vehicles, and small power generation systems. Review: switch failed after 1 month of service. - Bought 2 of these and one has failed. The failure occurred during full sun on a pv array running 370vdc at 16 amps. The switch is stuck in the on position but has disconnected current flow internally. The second one that was purchased still seems to be operating normally, however as there is now a doubt about reliability. I will have to replace both.
