YRL7-63DC DC series non-polar photovoltaic miniature circuit breakers are mainly used in DC solar combiner boxes or as battery switches.
High-quality flame-retardant material, cold and heat-resistant, stable performance. Power off quickly when power consumption is abnormal. Tunnel-type terminal blocks tightly wrap the wires, making the wiring more reliable.
Circuit breaker YRL7-63DC, which is a DC (Direct Current) circuit breaker with a rated voltage of 550V. This type of circuit breaker is designed specifically for use in DC electrical systems and provides protection against overloads and short circuits.
Here are some key features of the YRL7-63DC circuit breaker:
— Rated Voltage: 550V DC
— Rated Current: The specific rated current for this model would need to be specified.
— Breaking Capacity: The maximum fault current that the circuit breaker can safely interrupt.
— Trip Characteristics: The behavior of the circuit breaker when it detects an overload or short circuit, which can be categorized as B, C, or D types depending on the time-current curve.
— Mounting Type: The method by which the circuit breaker is installed, such as DIN rail mounting or panel mounting.
— Number of Poles: Refers to the number of separate circuits that the circuit breaker can control simultaneously.
It’s important to note that the information provided here is based on the general understanding of DC circuit breakers. For specific details about the YRL7-63DC circuit breaker, it’s recommended to refer to the manufacturer’s documentation or consult with a qualified professional.
