– AC-1: Used for controlling non-inductive or slightly inductive loads, such as resistance heating equipment.

Escenarios de aplicación típicos:

– Sistemas de control de motores (rango de potencia: 220kW@415V a 280kW@690V)

– Control of AC loads with a power factor ≥0.95

– Equipos de automatización industrial.

– Master switch control for lighting systems

– Other industrial applications requiring high-current switching

Características técnicas

Ventajas de rendimiento:

– High making and breaking capacity: Capable of withstanding a making current of 4000A and a breaking current of 3200A (440V y)

– Corriente soportada de corta duración: 3600A (≤40°C, 10 artículos de segunda clase), enhancing system reliability

– Amplio rango de operación de voltaje: The control coil operates stably within 85%~110% of the rated voltage, does not actuate below 70%, and releases reliably within 35%~50%

– Diseño de bajo consumo de energía: Only 15VA required in the holding state, reducing energy consumption

– High anti-interference capability: Withstands 8kV impulse voltage, adecuado para entornos industriales hostiles

Características estructurales:

– Two installation methods: base mounting or DIN rail mounting, facilitating on-site deployment

– Cableado del circuito principal: Can connect 2×150mm² cables or 30×5mm copper busbars, with a tightening torque of 35N·m

– circuito de control: Bolt-fastened terminals, capable of connecting 1~4mm² wires, with a torque of 1.2N·m

– Diseño modular, allowing addition of accessories such as auxiliary contacts and overload protection

Recomendaciones de aplicación

1. -Puntos clave de selección: Choose the appropriate duty cycle based on the load type (AC-3 for motor control, AC-1 para cargas resistivas)

2. Environmental Considerations: The installation location should be well-ventilated, with an ambient temperature not exceeding 55°C

3. Supporting Protection: It is recommended to use it with appropriate overload protection devices (como relés térmicos) to protect the motor and the contactor itself

4. Selección de cables: Para el circuito principal, select cables with sufficient cross-sectional area (≥150mm²) para garantizar una conexión de baja impedancia

5. Ciclo de mantenimiento: Inspeccionar periódicamente el estado del contacto.; a comprehensive inspection and cleaning at least once a year is recommended
