III. Structural Features

Compact, lightweight, low power consumption, long lifespan, and safe and reliable – providing a stable and dependable guarantee for power control.
The contactor is a protective type with a direct-acting mechanism, featuring double-break contacts, and boasts excellent electrical properties.
The accessory set, including auxiliary contact groups, air delay heads, thermal relays, etc., can be installed in a modular manner to form a variety of derivative product series, catering to different circuit control requirements.
The contactor can be mounted using screws, and also with 35mm and 75mm U-shaped international standard track for convenient and flexible installation.
Four: Usage Precautions

Check relevant technical data before installation to ensure the contactor matches the circuit parameters.
During installation, follow the specified conditions, align with human visual habits, and properly ground contactors with metal mounting plates.
The terminal screws should be tightened, and after verifying the wiring is correct, the attraction coil should be energized and de-energized several times without power to the main contactor. Only after confirming the operation is reliable can it be put into use.
If abnormal noise is detected during use, it may be due to dirt on the pole face of the iron core. It should be cleaned promptly.
Regular inspections of product components are required. Moving parts should not jam, fasteners must be secure, and any damaged parts should be replaced promptly.
