Description
BB2D-63(H) Series DC Miniature Circuit Breaker (hereinafter referred to as the circuit breaker) adopts arc striking and arc quenching technology, rapid make-and-break mechanism and current-limiting technology to break short-circuit currents in DC power distribution systems. Featuring non-polarized wiring, it facilitates wiring and prevents positive/negative polarity connection errors.
This circuit breaker is suitable for DC system circuits with a rated insulation voltage of 500 V. Its rated DC voltage is up to 250 V for single-pole version and up to 440 V for two-pole version, with rated current ranging from 1 A to 63 A. It provides overcurrent protection for DC circuit installations and electrical equipment in buildings and similar locations, and can also be used for infrequent make-and-break operations. It features compact size, high breaking capacity, easy installation and high tripping sensitivity. Designed for non-professional users, it is maintenance-free. It is widely applied in power plants, substations, telecommunications, transportation, metallurgy, mining and industrial sectors.
This product complies with GB/T 14048.2 and IEC 60947-2 standards and has obtained CE and CB certificates.
