The kit is complete: the breaker ships with the UVR and aux switches integrated, no separate accessory modules to order. The line-protection design means the trip curve is optimized for cable and busbar protection rather than motor starting, so match it to a feeder or main breaker role, not a motor branch circuit. Mounting is via screw-clamp to a mounting plate or DIN rail adapter (not included in the base breaker), so verify the panel's backplate layout before committing the BOM line. The breaker carries a trip indicator (no) and voltage trigger (no), so it's a thermal-magnetic or electronic trip unit without a separate shunt-trip as standard. Ground-fault monitoring is not included in this variant.","metaTitle":"Siemens 3VA2063-5KP32-0BC0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2063-5KP32-0BC0 molded case circuit breaker, 63 A continuous, 3-pole, 187 kA at 240 V interrupting capacity.
