Current Limiting Circuit Breaker Overview:
Technical Parameters:
● Rated Current (In A): Depending on application requirements, the rated current of the Current Limiting Circuit Breaker varies, ranging from 16A to 630A.
● Rated Ultimate Short-Circuit Breaking Capacity (kA): This indicates the maximum short-circuit current value that the circuit breaker can safely interrupt under a short-circuit fault. Different circuit breakers have varying breaking capacities to meet diverse application needs.
● Arc Distance (mm): During a short-circuit fault, an arc forms inside the circuit breaker. Arc distance is a crucial indicator for evaluating the breaker's safety performance.
● Control Circuit Parameters: Includes rated working voltage and parameters of the trip, shunt trip, undervoltage trip, etc.
Applications:
● Low-voltage networks or substation systems: Current Limiting Circuit Breakers are commonly used in low-voltage networks or substation systems for distributing electrical energy and infrequent line and power supply equipment conversions.
● Branch circuits with high breaking capacity: In branch circuits requiring high breaking capacities, current limiting circuit breakers effectively limit short-circuit currents and enhance circuit safety.
Specific Functions:
● Fast Disconnection: Current Limiting Circuit Breakers can quickly disconnect the circuit before the short-circuit current reaches its expected peak, thereby limiting fault current and reducing damage to electrical equipment and fire risks.
● Electromagnetic Tripping: Through an electromagnetic tripping mechanism, the current limiting circuit breaker swiftly cuts off the circuit during a fault.
Other Features:
● Accessories and Configurations: Current Limiting Circuit Breakers can be equipped with various accessories such as shunt releases, auxiliary contacts, etc., to meet diverse application needs.
● Size and Installation: The circuit breaker's appearance and installation dimensions are also crucial factors to consider during selection.
