Detailed Technical Specifications

Usage Notes

1. Ensure the power supply is disconnected before installation, and confirm no voltage in the circuit using professional voltage detection equipment.
2. Only use under the rated voltage (230ВАК).
3. Ensure wiring is secure to avoid overheating caused by loose connections.
4. Regularly inspect the circuit breaker status to ensure proper operation.

The Schneider EZ7DPN-C16 (EZ711603G) is an economical 1P+N miniature circuit breaker with reliable overload and short-circuit protection functions, suitable for single-phase distribution systems in residential, коммерческий, and industrial settings. The Type C trip characteristic makes it particularly suitable for protecting conventional loads such as lighting and sockets, while the 4.5kA breaking capacity is sufficient to handle short-circuit faults in general household and small commercial environments.

Installation Specifications for Schneider EZ7DPN-C16 Circuit Breaker (EZ711603G)

1. Safety Preparation
2. Power Disconnection: Disconnect the upstream power supply before installation, and confirm no voltage in the circuit using professional voltage detection equipment.
3. Professional Installation: Must be installed by qualified electricians in compliance with electrical safety standards (NFPA 70E, ГБ 50149, и т. д.).
4. Personal Protective Equipment (PPE): Wear insulating gloves, safety goggles, and other PPE.
5. Installation Environment:

Dry, well-ventilated environment free of corrosive gases.

Температура окружающей среды: -5℃~40℃, relative humidity ≤90% (при 25℃).

Avoid vibration, высокотемпературный, or humid locations.

1. Этапы установки
2. DIN Rail Installation (if not pre-installed in the distribution box)

Use a 35mm standard DIN rail, ensuring the rail levelness ≤2mm/m.

Fix the rail to the distribution box base with M4 screws, spacing ≤300mm.

The rail must be reliably grounded (connect to the distribution box grounding bar with a yellow-green grounding wire).

2. Circuit Breaker Installation

Vertical Installation (Recommended): Handle facing upward, tilt angle not exceeding 5°.

Horizontal Installation (Special Cases): Ensure flexible operation and that the closing direction complies with markings.

Specific Operations:

1. Align the buckle on the back of the circuit breaker with the upper edge of the DIN rail.
2. Press the circuit breaker downward until a “click” sound is heard, indicating it is securely snapped into the rail.

III. Характеристики проводки

1. Wiring Principles

“Top In, Bottom Out”: Upper terminals for power incoming wires, lower terminals for load outgoing wires.

“Neutral on Left, Phase on Right”: When facing the front of the circuit breaker, connect the neutral wire (Н) to the left terminal and the phase wire (л) to the right terminal.

Strict Distinction: The N pole of the 1P+N circuit breaker has no protection function; reverse connection of phase and neutral wires is strictly prohibited.

2. Terminal Connection Steps
3. Strip the wire insulation (approximately 10-12mm) without damaging the conductor.
4. Insert the wire into the corresponding terminal (L for phase wire, N для нейтрального провода).
5. First hand-tighten the terminal screw until the wire is secure, then tighten it to the specified torque with a torque wrench.

Terminal Markings:

л (or unmarked): Connect to phase wire (live wire).

Н: Connect to neutral wire.

1. Technical Parameters and Installation Requirements

1. Меры предосторожности при установке
2. Key Prohibitions

Prohibited Inverted Installation: Upside-down installation is not allowed.

Prohibited Reverse Connection: Incorrect connection of N and L poles is forbidden; в противном случае, the breaker may not trip in case of leakage.

Prohibited Neutral Wire Parallel Connection: When multiple residual current circuit breakers are installed side by side, parallel connection of outgoing neutral wires is strictly prohibited.

2. Clearance Requirements

Horizontal distance from adjacent equipment≥200mm, vertical distance≥150mm for easy operation and maintenance.

Distance between high-voltage and low-voltage equipment in the distribution box ≥50mm to reduce interference.

3. Wiring Points

Ensure terminal connections are secure to avoid overheating affecting protection performance.

Use a PZ-type Phillips screwdriver (recommended) to prevent thread slipping.

Do not press the wire insulation into the terminal to ensure electrical clearance.

1. Post-Installation Inspection
2. Insulation Test: Check circuit insulation with an insulation resistance tester (≥0.5MΩ).
3. Function Test:

Manually close and open the breaker 3 times to confirm flexible operation.

Conduct simulated overload and short-circuit tests if conditions permit (performed by professionals).

3. Marking: Label the circuit purpose on the breaker or distribution box for easy maintenance.

VII. Рекомендации по техническому обслуживанию

Regularly inspect the tightness of circuit breaker connections, especially after long-term use.

Keep the circuit breaker surface clean to avoid dust accumulation affecting heat dissipation.

If the breaker trips frequently, troubleshoot the fault first rather than resetting repeatedly.

The key to installing the Schneider EZ7DPN-C16 circuit breaker lies in: safe power disconnection, correct installation (vertical or horizontal), standardized wiring (“Top In, Bottom Out”; “Neutral on Left, Phase on Right”), and reliable fixation on a 35mm DIN rail with proper grounding. После установки, perform a function test to ensure normal protection performance.

Translation Notes for Export Business:

1. Terminology Consistency: Adopted international standard electrical terms (например, “1П+Н” retained, “trip characteristic” instead of “tripping feature”) for global customer understanding.
