Ⅲ. Functions and Applications
Main Functions:
– 過負荷保護: When the circuit current exceeds the rated value, the circuit breaker will trip within a certain period.
– 短絡保護: Quickly (in milliseconds) cuts off the circuit when a short circuit occurs.
– Disconnects both phase wire and neutral wire simultaneously to enhance safety.
典型的なアプリケーションシナリオ:
– Terminal circuit protection for residential distribution boxes (lighting, ソケット, 等)
– 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
- Comparison with Other Models
Common Specifications of EZ7DPN Series:
– EZ7DPN C6A/C10A/C16A/C20A/C25A/C32A/C40A
Differences from EZ7DPN Vigi Series:
– EZ7DPN: Only provides overload and short-circuit protection.
– EZ7DPN Vigi: Added leakage protection function (例えば, 30ミリアンペア), suitable for occasions requiring leakage protection.
- Installation and Usage Instructions
設置方法:
– Standard 35mm DIN rail installation, suitable for modular installation in distribution boxes.
Usage Precautions:
- Ensure the power supply is disconnected before installation to avoid electric shock risks.
- The circuit breaker should be installed vertically with the identification face upward.
- Connecting wires must be secured tightly to prevent overheating caused by looseness.
- Regularly check the status of the circuit breaker to ensure normal operation.
- Price Reference
Retail Price: Approximately 30-50 RMB per unit
Bulk Purchase Price: Can be as low as 25 RMB per unit
Ⅶ. まとめ
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, コマーシャル, 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.
注記: The correct product model should be EZ7DPN C16A (not EZ7DPNC16), and there are some non-standard writing methods in the market.
