Suitable for
Controlling lighting systems in large buildings
Managing heating and ventilation equipment
Switching high-current electrical loads in distribution boards
Automated power management in commercial installations
When it may not be suitable
This contactor is not intended for use in circuits requiring normally closed (NC) contacts, as it features four normally open contacts only. Additionally, it is not suitable for direct current (DC) control applications, as it is specifically designed for a 230V AC control voltage.
Key specifications
Rated current: 63A
Contact configuration: 4 normally open (NO)
Control voltage: 230V AC
Weight: 0.435 kg
Mounting: Modular DIN rail
How to use
The device should be installed by a qualified professional within a standard distribution board on a DIN rail. Ensure that the control circuit is connected to the appropriate terminals for the 230V AC supply. Once installed, the contactor will automatically switch the connected load when the control signal is applied to the coil. Always verify that the load current does not exceed the 63A rating to prevent overheating or damage to the unit.
What to consider before purchase
Verify that your control system provides 230V AC voltage
Ensure the load requirements do not exceed 63A
Check available space in your distribution board for modular components
Confirm that your application requires four normally open contacts
