2D matrix code of production
This is a production code that contains the article number of the device, production date,
production facility and other information in encoded form.
This code can also be scanned with the free "Industry Support" app for smartphone and
tablet PC. You then receive the same information as with the QR code on the device front.
In the accessory compartment on the right, you can find two adhesive label inserts for
3VA UL: one for use of the circuit breaker in IEC applications and the other for use of the
molded case circuit breaker in UL applications.
When an accessory (e.g. motor operator or manual operator) is mounted on the circuit
breaker, this adhesive label can be attached to the accessory.
The adhesive labels are shown in the following example of the 3VA62 molded case circuit
breaker. The adhesive labels are slightly different for molded case circuit breakers (MCCB),
motor circuit protectors (MCP) and molded case switches (MCS). Ultimately, the following
information is always specified:
● Article number MLFB
● Size
● Rated currents
● Breaking capacities at listed voltages
