It includes phase failure detection and comes with one auxiliary switch plus one trip alarm switch.
Breaking capacity steps down with voltage: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. At 690 V the 3.7 kA figure is the limiting case; if your system runs 690 V with fault currents above that, this breaker is not the right choice. The 86 mm depth, 105 mm width, and 181 mm height fit standard MCCB panel cutouts.
It is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
The depth is 86 mm (3.39 in).
The width is 105 mm (4.13 in).
No — the 3VA2116-5HL32-0AK0 is a 16 A distribution breaker without phase failure detection; the 3VA2140-5MN32-0AG0 is a 40 A motor protection breaker with that detection. The footprint may be similar (both are 3-pole SENTRON 3VA frames), but the current rating and protection function are different, so rewiring and coordination adjustment are needed.
As a Siemens SENTRON MCCB, it carries IEC/UL certifications typical for the series. Specific compliance documentation (RoHS, REACH, UL file number) is available from the manufacturer upon request.
