DISCONNECT terminal blocks are commonly used in the field of test and measurement. Available from NHP Electrical Engineering , the Series 280 and 281 Cage Clamp terminals from Wago feature a disconnecting tab to achieve the disconnect function.
The disconnecting tab has been designed to provide maximum operational safety. Once in the disconnect position, the disconnecting tab can be protected against unintentional reconnection by using the disconnect lock.
The only means in which the disconnect lock can be removed is through a conscious act or use of a tool.
The disconnect lock provides easy handling, adds to maximum safety and provides a non-ambiguous, clear identification of the position of the disconnecting tab.
