24 V module

With the aid of the 24 volt module, the ETU electronic trip unit of the 3VA6 molded case
circuit breakers can be permanently activated.
The module is installed in the right-hand accessory compartment and has 4 slots.
The following advantages arise from the use of the 24 V module:
● Activated display even when the circuit breaker is switched off or no current is flowing
through the main circuit.
● Backlighting permanently activated
● Through activation of the ETUs, it is possible to test and change setting parameters
(ETUs 5-series and 8-series)
● Faster tripping of the 3VA6 molded case circuit breaker on connecting to a short-circuit by
an already active ETU.
There are two connection points available for ground and 24 V DC so that looping through of
the voltage can be done very easily.
