It should not be used in environments exceeding its specified current or voltage capacity, nor in highly corrosive or explosive atmospheres without appropriate protective enclosures.

Key specifications

• Number of poles: 3
• Control coil voltage: 230V AC
• Auxiliary contacts: 1 normally open (NO)
• Application: Industrial and automation switching

How to use

Installation should be performed by qualified personnel in accordance with local electrical regulations. The contactor is typically mounted on a standard DIN rail within a control cabinet. Connect the power supply lines to the main terminals and the control circuit to the coil terminals. Ensure that all connections are tightened securely to prevent overheating. The auxiliary contact can be wired to a PLC or indicator light to monitor the status of the contactor.

What to consider before purchase

• Verify that the control voltage matches your existing system requirements.
• Ensure the current rating is sufficient for the load being switched.
• Check available space in your electrical enclosure for mounting.
• Confirm the number of auxiliary contacts meets your automation needs.

Usage recommendations

Regularly inspect the terminal connections for tightness and check for any signs of wear or debris accumulation to maintain optimal performance and safety.
