Vendor Description
Siemens Class CLM magnetically and mechanically held lighting contactors are used in applications where it is critical that the contacts remain in the closed position during loss of control power. These contactors do not change state and disconnect power from the load during a loss of control power whether momentary or sustained. That is because the operating coil is not required to be continuously energized. Since the coil is not continuously energized, energy is saved and coil hum is eliminated. This makes the contactor also ideal for applications where quite operation is critical.
