Automatic DC circuit breaker 2P, 40A, 1000VDC

DC circuit breaker, 2-pole, 40A, 1000V DC Features: The DC circuit breaker is designed to protect the DC circuits of solar panels from overcurrent. It is suitable for use in photovoltaic power generation and distribution systems, such as small-circuit photovoltaic switch box, DC controller and other electrical equipment. The rated voltage of a DC circuit breaker can reach 1000V and the rated operating current is 40A. It is equipped with an arc safety barrier and a current limiting system, which allows for quick disconnection of the photovoltaic system's DC fault current and provides protection against reverse current. Ensures reliable operation of DC systems. Used for insulation, short circuit and overload protection. Modular design. Convenient mounting on a DIN rail. Complies with IEC/EN 60947-2 standards and environmental protection requirements. Technical data: Number of contacts: 2. Rated voltage (Ue): DC 1000V. Insulation voltage (Ui): DC 1500V.
