Product Description
The DC Three-segment Miniature Circuit Breaker NDB2ZB-63 products feature three-stage protection functions: long delay for overload, short delay for short circuit, and instantaneous action for short circuit. They can be used in DC distribution systems with a rated working current of 63A or below, enabling full selectivity protection between upstream and downstream circuit breakers. This ensures that the system can effectively protect against short circuit faults while avoiding the issue of inadvertent operation of upstream circuit breakers due to downstream short circuit currents, guaranteeing the safe and reliable operation of the system, and also providing isolation functionality.
