Schneider ICT63A Contactor

The Schneider ICT63A is a modular Contattore CA 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, illuminazione, and heating equipment.

Core Parameters

Nota: AC7a is suitable for slightly inductive loads (such as lighting), and AC7b is suitable for motor loads (come i tifosi). The same contactor has different rated currents for different load types.

Main Models and Differences

Nota: Some models have manual operation versions (per esempio., A9C21864), which are suitable for commissioning and emergency situations.

Scenari applicativi

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

Technical Features

1. Compact Design:

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. High Reliability:

Complies with IEC/EN 61095 standard

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

Electrical life of up to 100,000 operazioni (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

Installation and Maintenance

Punti chiave dell'installazione

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

Circuito principale: 6~25mm² singlestrand hard wire or 6~16mm² flexible wire

Circuito di controllo: 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

Raccomandazioni per la manutenzione

Ispezione regolare:

Check if contacts are ablated or deformed

Check if connections are loose

Remove dust and foreign objects

Ciclo di manutenzione:

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

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

Considerazioni sulla selezione

1. Selection Based on Load Type:

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

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

Carichi misti: 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 (Normalmente aperto) contatti

Need status feedback: Select NO+NC combination

Special safety control: Select NC (Normalmente chiuso) contatti
