ثالثا. Functions and Applications
الوظائف الرئيسية:
– حماية الزائد: When the circuit current exceeds the rated value, the circuit breaker will trip within a certain period.
– Short-Circuit Protection: Quickly (in milliseconds) cuts off the circuit when a short circuit occurs.
– Disconnects both phase wire and neutral wire simultaneously to enhance safety.
سيناريوهات التطبيق النموذجية:
– Terminal circuit protection for residential distribution boxes (lighting, مآخذ, إلخ.)
– Power distribution systems in commercial buildings
– Single-phase power supply protection for industrial equipment
– Various occasions requiring simultaneous control of phase wire and neutral wire

سابعا. ملخص
The Schneider EZ7DPN C16A is a miniature circuit breaker with 1P+N structure, mainly used for overload and short-circuit protection of single-phase 230V circuits, and is suitable for multiple scenarios such as residential, commercial, and industrial applications. Its Type C tripping characteristic is suitable for general power distribution protection, the 4.5kA breaking capacity is sufficient to handle common short-circuit faults, and the standard width of 18mm facilitates dense installation in distribution boxes. If leakage protection is required, products from the EZ7DPN Vigi series can be selected.
ملحوظة: The correct product model should be EZ7DPN C16A (not EZ7DPNC16), and there are some non-standard writing methods in the market.
