Product details

Rated 187 kA at 240 V and 121 kA at 415/440 V, it handles high available fault currents common in industrial distribution panels without cascading upstream. At 500 V the breaking capacity is 75.6 kA; at 690 V it drops to 3.7 kA — a normal curve for a 40 A frame, but worth noting if the line side runs at 690 V.

Integration & Fit

The base switch is order code 3VA21405MN320AA0, meaning the breaker core is a fixed unit — not a plug-in or draw-out variant. Field-installable accessories are limited to the provided shunt trip and auxiliary switch block; no communication module or ground-fault module is fitted.

Ratings & Protection

Maximum power loss is 1.6 W at rated current, which keeps enclosure heating minimal.

Frequently asked questions

Does 3VA2140-5MN32-0JL0 include phase failure detection?

Yes, it includes phase failure detection.

What auxiliary switches and releases are fitted on 3VA2140-5MN32-0JL0?

Two auxiliary switches, one trip alarm switch, one electrical alarm switch (HQ), and a shunt trip release (STL).
