The Chint NXB63-C6+AX-X1 circuit breaker is a Miniature Circuit Breaker (MCB) commonly used in low-voltage power distribution systems, 과부하 및 단락 보호 제공. 그만큼 “+AX-X1” likely indicates the inclusion of auxiliary contact (도끼) 부속품. Below is a general guide to its installation method and precautions (always refer to the product manual for specifics):

1. 설치 전 준비
2. Confirm Product Specifications

– Ensure the circuit breaker model matches requirements (C6 denotes a rated current of 6A, suitable for low-current circuits like lighting).

– The AX-X1 accessory is typically an auxiliary contact for remote signal feedback (예를 들어, connecting to alarm or control systems); verify its function and wiring method.

2. Tools and Materials

– Tools needed: 드라이버 ( Phillips or flathead), 와이어 스트리퍼, 멀티미터, rail installation tool (필요한 경우).

– 재료: 표준 35mm DIN 레일 (for mounting the circuit breaker), 전선 (selected by load current rating).

3. Safety Power Disconnection

– Always disconnect the upstream power supply before installation to ensure the circuit is de-energized and avoid electric shock hazards.

1. 설치 단계
2. 레일 장착 (Main Circuit Breaker)

Rail Type: Use a standard 35mm DIN rail (common in distribution panels).

장착 방법:

1. Align the clips at the bottom of the circuit breaker with the rail, press down firmly until a “딸깍 하는 소리” is heard to confirm secure attachment.
2. To remove, use a screwdriver or specialized tool to press the clip on the side of the circuit breaker and pull upward.
3. 액세서리 설치 (AX-X1 Auxiliary Contact)

설치 위치: Auxiliary contacts are typically mounted on the right side of the main circuit breaker (some models may support left or rear mounting; 설명서를 참조하세요).

장착 방법:

1. Align the卡槽 (슬롯) of the auxiliary contact with the interface of the main circuit breaker, push horizontally to fix (may require screws or clips for locking).
2. Ensure the accessory is tightly connected to the main circuit breaker without looseness.
3. Wiring Operations

주회로 배선 (Circuit Breaker Body):

Incoming Terminals (맨 위): Connect to the power supply side (usually live wire L and neutral wire N; note that the neutral wire may need to be connected via a terminal block, depending on whether the circuit breaker has a neutral terminal).

Outgoing Terminals (맨 아래): Connect to the load side (예를 들어, 램프, 소켓).

지침:

– Wire cross-sectional area should match the current (1.5mm² or 2.5mm² copper wire is recommended for 6A current).

– Strip wires to an appropriate length to avoid short circuits; ensure terminal screws are tightened securely.

Accessory Wiring (AX-X1 Auxiliary Contact):

– Auxiliary contacts typically have 2-4 터미널 (예를 들어, NO 평상시 열림, NC normally closed) for connecting control circuits (예를 들어, to energy meters, alarm systems, or PLCs).

– Connect wires to the corresponding terminals as needed (marked such as “1-2” for normally open, “3-4” for normally closed), and tighten the screws.

III. Post-Installation Inspection and Testing

1. 육안검사

– Confirm the circuit breaker and accessories are firmly installed without tilting or looseness; ensure no exposed copper wires and tight terminal screws.

2. 기능 테스트

– Close the upstream power supply and check if the circuit breaker indicator (가능하다면) is normal.

– Manually switch the circuit breaker on and off to test smooth operation and whether auxiliary contacts actuate synchronously (use a multimeter to measure contact continuity).

– Simulate overload or short-circuit conditions (exercise caution) to test if the circuit breaker trips promptly for protection.

3. Safety Verification

– Use a multimeter to measure line insulation resistance to ensure no grounding or short-circuit faults.

– Check that the distribution panel is reliably grounded and complies with electrical installation codes.

2. Polarity and Neutral Handling

– Single-pole circuit breakers (1피) usually connect only the live wire; the neutral wire must be connected via the distribution panel’s neutral terminal block. For 1P+N circuit breakers, distinguish the incoming direction of the live wire (엘) 그리고 중성선 (N) (the N terminal is typically a fixed hole and not interruptible).

2. 환경 요구 사항

– Install in dry, ventilated areas free of corrosive gases, avoiding high-temperature or humid environments.

– Leave sufficient space in the distribution panel to ensure good heat dissipation.

3. 전문적인 운영

– If unfamiliar with electrical installation, consult a licensed electrician to ensure compliance with local electrical codes (예를 들어, China’s GB standards).

We hope this information helps! Always prioritize safety and follow proper procedures during installation.
