Sphere of application
KNB1-63 series Miniature Circuit Breaker is nice in appearance, reasonable in structure, sound in feature and high in breaking capacity. Installed with standard DIN rail, it is convenient and easy in usage. It is mainly used in the line of AC 50/60Hz, rated working voltage to 240V/415V, and rated current to 63A as protection against overload and short-circuit. It can be used as infrequent on-and-off operation and changeover.
It complies with standard of GB10963 and IEC/EN60898.
