Automation systems requiring reliable circuit control
Heating and lighting control applications
This contactor may not be suitable for applications requiring DC control voltages, as it is specifically designed for a 230V AC coil. It is also not intended for use in environments exceeding its specified thermal or electrical ratings, which could lead to premature component failure or safety hazards.
Key specifications
Number of poles: 3
Rated operational current: 51A
Control coil voltage: 230V AC
Auxiliary contacts: 1NO + 1NC
Size: S2
To use the contactor, mount it securely onto a standard DIN rail or a flat surface within an electrical enclosure. Connect the main power lines to the primary terminals and wire the control circuit to the coil terminals. Ensure that all connections are tightened to the specified torque values to prevent overheating. Once installed, the auxiliary contacts can be wired to your PLC or monitoring system to provide status feedback on the contactor state.
What to consider before purchase
Verify that your control circuit voltage matches the 230V AC coil requirement.
Ensure the 51A current rating is sufficient for your specific motor or load.
Check available space in your control cabinet for the S2 frame size.
Confirm that the auxiliary contact configuration meets your interlocking needs.
Usage recommendations: Always perform a thorough inspection of all electrical connections before initial startup. Ensure that the device is protected by appropriate circuit breakers or fuses to prevent damage from short circuits or overloads. Regularly check for signs of wear on the contact surfaces to maintain optimal performance.
