1. Product Composition and Model Description
2. Basic Model IC65N C20Aシュナイダー 低圧モールドケースサーキットブレーカ EZD100B3015MAN

– Belongs to Schneider’s IC65N series of miniature circuit breakers (MCBs). C20A indicates a rated current of 20A, with a Type C tripping curve (suitable for lighting and general power distribution loads, with overload protection sensitivity of 5-10 定格電流の倍).

– Pole options: 1P, 2P, 3P, 4P. The default breaking capacity is 6kA (N type), while some models can reach 10kA (H type) or 15kA (L type).

2. Implementation of Residual Current Protection Function

Integrated model: Achieved through Vigi iC65 series residual current accessories, such as Vigi iC65 2P C20A, which directly provides residual current protection with a rated residual current operating current of 30mA (AC type), suitable for AC circuits.

Accessory combination: The IC65N circuit breaker can be paired with Vigi VE (electronic) or VM (electromagnetic) accessories, requiring on-site assembly. The first disassembly leaves visible damage to ensure safety.

2P: Protects both live and neutral wires, suitable for single-phase circuits requiring comprehensive residual current protection (例えば, home distribution boxes).

1P+N: Only protects the live wire, but the neutral wire can be indirectly protected via accessories, offering a more compact design.

2. Safety and CertificationsChint の NB1-63DC シリーズ DC サーキットブレーカー Price

– Complies with China’s GB16917 standard and holds CCC certification, providing triple protection against overload, 短絡, and residual current.

– The breaking capacity meets the needs of residential and light industrial applications, with 6kA (N type) addressing most short-circuit scenarios.

Ⅲ. Application Scenarios and Installation Recommendations

1. 代表的な用途

Home power distribution: The 2P C20A model is suitable for 20A load circuits such as air conditioners and electric water heaters, while protecting personal safety.

Commercial and industrial use: 3P/4P models can be used for three-phase equipment, such as small motors or branch circuits of distribution boxes.

2. Installation Notes

Accessory installation: Vigi accessories must align with the lower terminals of the circuit breaker, fixed with a yellow card after fastening to ensure reliable electrical connections.

Wiring specifications: Connect the power supply to the inlet terminal and the load to the outlet terminal. The neutral wire must be connected to a dedicated terminal to avoid reverse connection.

Environmental requirements: Installation temperature range: -5°C to +40°C, altitude ≤ 2000 メートル. Avoid humid or corrosive environments.

2. Price Reference

Integrated model: The price of Vigi iC65 2P C20A is approximately 135-411 人民元, subject to the number of poles and accessory configurations.

Accessory combination: IC65N circuit breaker (approx. 30-80 人民元) + Vigi accessories (approx. 100-200 人民元), with a total cost slightly lower than the integrated model.

1. FAQ
2. Q: Can IC65N C20A be used as an RCCB alone?

あ: No. It must be paired with Vigi accessories or choose the Vigi iC65 model with integrated residual current protection.

2. Q: How to distinguish between AC-type and A-type RCCBs?

あ: AC-type detects only AC residual current, suitable for purely resistive loads; A-type can detect residual current with pulsating DC (例えば, frequency converter equipment). Choose based on the load type.

3. Q: How to test the residual current function after installation?

あ: Press the “テスト” button on the accessory. サーキットブレーカーはすぐに落ちるはずです; さもないと, check the wiring or replace the device.

1. まとめ

Schneider’s IC65N C20A series achieves residual current protection through Vigi accessories or integrated models, featuring high reliability and flexibility for various scenarios. When selecting, comprehensively consider the load type, pole requirements, and installation environment. Prioritize purchasing genuine products through official channels to ensure safety and performance standards.
