Product details

The Siemens SENTRON 3VA2163-7MS32-0AH0 is a 3-pole molded case circuit breaker (MCCB) rated 63 A continuously across the full 40 °C to 70 °C ambient range — no derating needed in a warm panel. The adjustable thermal-magnetic trip unit has a minimum trip setting of 189 A and a maximum of 945 A.

The basic switch assembly is order code 3VA2163-7MS32-0AA0, which is the core switching mechanism. The -0AH0 suffix indicates the factory-fitted accessories (the auxiliary and alarm switches). If you're replacing just the switch body, order the -0AA0; if you need the full assembled unit with auxiliaries, this -0AH0 is the drop-in.
