Product details

The Siemens 3VA2163-0MS32-0AA0 is a SENTRON 3VA2 molded case circuit breaker (MCCB) designed for motor protection, rated 63 A continuous with an 800 V insulation voltage. Breaking capacity is 440 kA at 415 V AC and 187 kA at 690 V AC — enough headroom for high-fault installations like industrial substations or large motor control centers where selective coordination is required. The 3-pole design fits standard DIN-rail or panel-mount footprints. Rated current holds flat at 63 A across the full ambient range from 40 °C to 70 °C, so no derating is needed in a warm enclosure.

Dimensions & Panel Fit

The breaker measures 86 mm deep, 105 mm wide, and 181 mm high. These dimensions match the standard 3VA2 frame footprint; if you are replacing a 3VA2163-8HM32-0AA0 or similar sibling in the same frame size, the mounting hole pattern and bus-bar spacing are identical — no rewiring or panel modification needed.

Frequently asked questions

What is the breaking capacity of this MCCB?

The 3VA2163-0MS32-0AA0 has a breaking capacity of 440 kA at 415 V AC and 187 kA at 690 V AC, suitable for high-fault-current installations.

Will 3VA2163-0MS32-0AA0 drop into a panel specified around 3VA2163-8HM32-0AA0?

Yes, both are 3VA2 frame size with identical dimensions (86 x 105 x 181 mm) and the same 3-pole bus-bar spacing. The panel layout and wiring remain unchanged.
