Noark 4 Pole 50A 1000VDC 6ka Noark 4 Pole 50A 1000VDC 6ka is a 4 pole DC Miniature Circuit Breaker, DIN mounted. Ideal for any DC circuits, including protection of power supplies in automation and control systems and solar PV strings. 4 Pole: This indicates that the breaker is designed to interrupt four separate electrical circuits simultaneously. In a 4-pole breaker, you typically find this in applications needing to disconnect three-phase and neutral conductors. 50A: This denotes the current rating, meaning the breaker can handle up to 50 Amperes before tripping. 1000VDC: This is the voltage rating, specifying that the breaker is suitable for use in circuits with up to 1000 Volts of direct current (DC). 6ka: This is the breaking capacity, indicating that the breaker can safely interrupt a fault current of up to 6 kiloamperes (6000 Amperes). Typical Applications This type of circuit breaker is typically used in photovoltaic (solar power) systems, battery energy storage systems, and other DC applications where high voltage and high current protection are required. Key Features High Voltage Rating: Suitable for up to 1000V DC applications. Multiple Poles: Can protect multiple circuits simultaneously, ideal for complex electrical systems. High Breaking Capacity: Can safely interrupt high fault currents, protecting equipment and enhancing safety.
