1. Product Composition and Model Description
2. Basic Model IC65N C20ASchneider low-voltage molded case circuit breaker 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 정격 전류의 배).

– 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.

2. Electrical Parameters

정격전압: 230V/400V (single-phase/three-phase).

Residual current operating characteristics: AC type, capable of detecting power-frequency sinusoidal residual current, with an operating time ≤ 0.1 초.

Pole selection슈나이더 회로 차단기 가격:

2P: Protects both live and neutral wires, suitable for single-phase circuits requiring comprehensive residual current protection (예를 들어, 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 CertificationsChint의 NB1-63DC 계열 DC 회로 차단기 가격

– Complies with China’s GB16917 standard and holds CCC certification, providing triple protection against overload, short circuit, 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. 일반적인 응용 분야

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 meters. Avoid humid or corrosive environments.

2. 가격 참고

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

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

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

에이: 아니요. It must be paired with Vigi accessories or choose the Vigi iC65 model with integrated residual current protection.

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

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

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

에이: Press the “TEST” button on the accessory. The circuit breaker should trip immediately; 그렇지 않으면, check the wiring or replace the device.
