Automatic Control Contactor

The series of Automatic Control Contactors is designed as a core component for automated electrical switching systems. These Automatic Control Contactors are suitable for alternating current circuits with a frequency of 50Hz and a rated operational voltage up to 660V, handling currents up to 95A (3-phase ≤440V). They are primarily used for the remote making and breaking of electrical circuits, forming the backbone of automated control panels. Their robust design also makes them an excellent choice for applications requiring the frequent start-stop cycling of AC motors. When applied with an appropriately derated current rating (utilization category AC-4), these Automatic Control Contactors are capable of managing demanding control sequences like plugging and reversing for squirrel-cage induction motors. For enhanced system integrity, these Automatic Control Contactors can be integrated with thermal overload relays. This combination provides critical protection by disconnecting the circuit in the event of an operational overload, safeguarding both the motor and the contactor itself. To ensure the Automatic Control Contactor performs flawlessly within an automated setup, the following working and installation conditions are mandatory: a) Ambient air temperature range: ≥-5°C to +40°C, 24-hour average ≤+35°C. b) Installation site altitude: ≤2000m. c) Air relative humidity: ≤50% at +40°C. The average minimum temperature of the wettest month ≤+25°C, and its average maximum relative humidity ≤90%. d) Pollution degree: 3. e) Installation category: III. f) Shock/vibration: Must be installed in a location free from significant shaking, impact, or vibration. g) Mounting angle: Inclination of the mounting surface relative to vertical shall not exceed 5°. Engineered for reliability and consistent operation in automated environments, the Automatic Control Contactor series is a dependable choice for engineers building efficient and safe industrial control systems.
