Product Overview
The DZ47vP series phase + neutral miniature circuit breaker is a new-generation protection device specially designed for modern low-voltage terminal distribution systems. Featuring an integrated 1P+N structure, it combines phase line protection and neutral line control in one compact device, improving installation efficiency and space utilization. The DZ47vP circuit breaker is suitable for AC 50Hz low-voltage distribution systems with a rated operating voltage of AC 230V and a rated current range of 6-40A. It provides reliable protection against short circuits and overloads while also offering an isolation function for safer maintenance operations. The product adopts thermal-magnetic trip technology and provides two trip curve options: C Curve: Suitable for general distribution circuits, lighting systems, and socket circuits. The instantaneous tripping range is 5~10In. D Curve: Suitable for loads with high starting currents, such as motors and transformers. The instantaneous tripping range is 10~14In. With a rated short-circuit breaking capacity of 4.5kA, the DZ47vP provides stable and reliable fault interruption performance. The product adopts a standard 35mm DIN rail mounting design, supports top and bottom wiring, and is equipped with U-type terminals supporting conductors up to 16mm². The DZ47vP features 20,000 mechanical operations and 10,000 electrical operations, with an operating temperature range from -35℃ to +70℃, ensuring long-term reliable operation in various environments. The DZ47vP phase + neutral miniature circuit breaker is widely used in residential distribution boxes, commercial buildings, industrial control cabinets, lighting circuits, and other low-voltage terminal protection applications.
