Siemens 3VA1163-3EF36-0AA0 MCCB 3P 63A 25kA

The Siemens 3VA1163-3EF36-0AA0 is a SENTRON 3VA1 molded case circuit breaker designed for line protection in low-voltage power distribution. It is a 3-pole MCCB with a 63 A rated current and 25 kA breaking capacity at 415 V AC, making it a solid fit for commercial and industrial panels where reliable protection matters.

This model uses a TM240 thermal-magnetic trip unit with adjustable overload protection from 44 A to 63 A and adjustable short-circuit protection from 5 to 10 x In. That gives panel builders and maintenance teams more control than a basic fixed-setting breaker when matching protection to the load and installation.
