The Siemens SENTRON 3VA2140-0HL46-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for 40 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. The ETU320 electronic trip unit handles the overcurrent protection logic, with adjustable N-conductor protection (OFF or 100%).
The 140 mm width and 86 mm depth mean it occupies a standard four-module footprint in a SENTRON distribution board.

The depth is 86 mm (3.39 in), with a width of 140 mm (5.51 in) and height of 181 mm (7.13 in).
Both are 4-pole SENTRON MCCBs with the same 40 A frame and ETU320 trip unit, so the footprint and wiring pattern are identical. No rewiring needed for a direct swap.
Siemens SENTRON MCCBs carry CE marking and are designed to IEC 60947-2. RoHS and REACH declarations are available from Siemens documentation portals.
