3VA molded case circuit breakers with IEC certificate
210 Manual, 03/2019, A5E03603177010-03
With the aid of the 24 volt module, the ETU electronic trip unit of the 3VA2 molded case
circuit breaker can be permanently activated.
The module is installed in the right-hand accessory compartment and takes up four 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 (5-
series and 8-series ETUs)
● Faster tripping of the 3VA2 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, making looping through
of the voltage very easy.
