Schneider ICT63A Contactor

The Schneider ICT63A is a modular AC 접촉기 under Schneider Electric’s Acti9 series. It has a rated current of 63A and is specifically designed for residential and similar scenarios. It is suitable for remote control of motor control, 조명, and heating equipment.

핵심 매개변수

메모: AC7a is suitable for slightly inductive loads (such as lighting), and AC7b is suitable for motor loads (팬들과 같은). The same contactor has different rated currents for different load types.

Main Models and Differences

메모: Some models have manual operation versions (예를 들어, A9C21864), which are suitable for commissioning and emergency situations.

응용 시나리오

1. Residential and Commercial Appliance Control:

Air conditioning compressor control

Heating equipment such as water heaters and electric stoves

Ventilation system and fan control

2. Lighting Systems:

Commercial lighting control

Timed/zoned control of lighting in public areas

3. Small Motor Control:

Water pumps and compressors

Motors for rolling doors and garage doors

Small auxiliary motors in industrial equipment

기술적 특징

1. 컴팩트한 디자인:

Modular structure with a width occupying only 6 modules of 9mm (54mm)

Saves space in distribution boxes and enables easy installation

2. Low Power Consumption:

Pullin power consumption of 53VA and holding power consumption of only 6.5VA

Energyefficient and reduces heat generation

3. Quiet Operation:

Optimized electromagnetic system design with noise below 30dB

Suitable for residences and places requiring a quiet environment

4. 높은 신뢰성:

Complies with IEC/EN 61095 표준

Strong resistance to humidity and heat (works normally in an environment with 95% humidity and 55℃ temperature)

Electrical life of up to 100,000 운영 (for AC7a loads)

5. Safety Features:

Mechanical position indicator for easy status observation

IP20 protection to prevent accidental contact with live parts

Protective design for terminal blocks

설치 및 유지 관리

설치 요점

1. Vertical Installation: The inclination angle should not exceed 5° to ensure good heat dissipation
2. Electrical Connection:

Main circuit: 6~25mm² singlestrand hard wire or 6~16mm² flexible wire

Control circuit: 1.5~2.5mm² wires

Tightening torque: 3.5N·m for the main circuit and 0.8N·m for the control circuit

3. Heat Dissipation Space: Ensure sufficient ventilation space around the contactor

Maintenance Recommendations

Regular Inspection:

Check if contacts are ablated or deformed

Check if connections are loose

Remove dust and foreign objects

유지보수 주기:

Lowfrequency use (<15 operations/hour): Inspect once a year

Highfrequency use (>15 operations/hour): Inspect every 13 months

Selection Considerations

1. Selection Based on Load Type:

Slightly inductive loads such as lighting and heating: Select the rated current for AC7a (63에이)

Motor loads: Select the rated current for AC7b (20에이)

Mixed loads: Select according to the most severe conditions

2. Selection Based on Voltage and Pole Number:

Singlephase loads: 2P model

Threephase loads: 3P model

Threephase + neutral line system: 4P model

The control voltage must be consistent with the system (usually 220~240V AC)

3. Selection Based on Contact Configuration:

Only need to turn on/off: Select NO (Normally Open) contacts

Need status feedback: Select NO+NC combination

Special safety control: Select NC (Normally Closed) contacts
