General load switching in residential buildings
When it may not be suitable
This contactor is not intended for applications requiring switching currents significantly higher than 25A or for industrial environments with extreme vibration or harsh chemical conditions. It is also not suitable for direct control of high-voltage equipment exceeding the specified voltage ratings.
Key specifications
Rated operational current: 25A
Contact configuration: 3 normally open (NO) and 1 normally closed (NC)
Control voltage: 230-240V AC/DC
Operation: Hum-free
Mounting: Modular distribution board
How to use
The device is designed for mounting on a standard DIN rail within a distribution board. Ensure that the power supply is disconnected before beginning the installation. Connect the control wires to the coil terminals and the load wires to the designated power terminals according to the wiring diagram provided on the device housing. Once installed, verify that all connections are secure and that the voltage matches the specified range before energizing the circuit.
What to consider before purchase
Verify that the 25A current rating is sufficient for your specific load requirements.
Ensure the 230-240V AC/DC control voltage is compatible with your existing control system.
Check the available space in your distribution board to accommodate the modular width of the contactor.
Confirm that the 3NO/1NC contact configuration meets your circuit logic needs.
