Product details

The basic switch inside is order code 3VA21405MN320AA0, which is the interchangeable thermal-magnetic trip unit. If a panel already carries a 3VA frame, the trip unit swaps independently of the case.

Fit and wiring details

The depth leaves clearance behind a standard gland plate. Built-in auxiliary switch configuration: two auxiliary switches plus one trip alarm switch. The auxiliary release is a shunt trip (STL) — that's a separate coil that trips the breaker on command from an emergency-stop circuit or a remote relay. No undervoltage release on this variant. Power loss at rated load is 1.6 W maximum — negligible for panel thermal budgeting.

Coordination and selectivity note

The 121 kA at 415 V and 75.6 kA at 500 V give this MCCB enough interrupting capacity to serve as a main breaker in most 400 V distribution boards fed by a 1 MVA or smaller transformer. Selectivity with downstream 10–25 A miniature breakers is achievable with the right time-current curve — the trip indicator and voltage trigger aid in troubleshooting.

Frequently asked questions

Will 3VA2140-5MN32-0HH0 drop into a panel specified around 3VA1110-5EF32-0AM0 without rewiring?

Both are 3-pole SENTRON 3VA frame breakers on the same DIN-rail footprint, so the physical swap is straightforward. However, the 3VA2140-5MN32-0HH0 is a 40 A motor-protection variant with a shunt trip (STL) and two auxiliary switches plus a trip alarm, while the 3VA1110-5EF32-0AM0 is a different rating and accessory configuration. Verify the trip-unit setting and auxiliary wiring against the existing panel schematic before committing.
