Issue
The user wants to know the inrush and hold-in power consumption of the LC1D50 contactor when supplied with 220VDC control voltage.
Product Line
TeSys Deca
Environment
LC1D50 contactors with DC coil control supply (12VDC to 440VDC)
Cause
The user needs this information to properly size the control power supply and ensure compatibility with the application.
Resolution
The LC1D50 contactor with DC coil control supply has the following power consumption values, which are consistent across all DC voltage ranges (from 12VDC to 440VDC):
- Inrush power: 19 W at 20 °C
- Hold-in (sealed) power: 7.4 W at 20 °C
These values are specified in the official catalog and datasheet.
The inrush power is the peak consumption during coil energization, while the hold-in power is the steady-state consumption after the contactor is closed.
