CDB6Pi Phase + Neutral Miniature Circuit Breaker
The CDB6Pi series phase and neutral miniature circuit breaker is specially designed for single-phase low-voltage AC distribution systems, integrating short circuit protection, overload protection, and electrical isolation functions to protect electrical circuits and terminal equipment.
The product adopts a 1P+N pole configuration, with a rated operating voltage of 230VAC and rated current options from 6A to 40A, making it suitable for residential, commercial, and industrial terminal distribution applications.
CDB6Pi adopts thermal-magnetic tripping technology and provides C and D tripping curves, meeting the protection requirements of standard loads and equipment with higher starting currents.
With a compact structure and reliable performance, the circuit breaker supports standard 35mm DIN rail installation, features U-type terminals, and allows both top and bottom wiring for flexible installation.
The CDB6Pi series is widely used in residential distribution boards, commercial electrical systems, industrial control cabinets, and low-voltage terminal protection applications.
The product complies with GB/T 10963.1 and IEC/EN 60898-1 standards and meets CCC, CE, and RoHS certification requirements.
