CC-D048-W Closing coil; DC 24 – 48V

The closing coil is a device to close the breaker by remote control. Only one closing signal (about 100 msec.) is sent even when the closing coil supply is maintained ON. An interlock to prevent pumping is provided electrically. Closing time is from the initial energization of the closing coil to the completion of the closing of the main contacts. As CC is one-pulse driven, it is not necessary to insert AXb for burning prevention pur poses. Inserting AXb will cause anti-pumping function to be ineffective.
