Part identity and key ratings
The Siemens SENTRON 3VA2163-5JP32-0BH0 is a 3-pole molded case circuit breaker (MCCB) rated for line-protection duty. Its continuous current is 63 A across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling, which simplifies panel thermal budgeting. Interrupting capacity is 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. That 187 kA at 240 V is a high-fault rating — it handles utility-side fault contributions without cascading upstream breakers in most North American 240 V panelboards.
Panel fit and auxiliary complement
Dimensions are 105 mm wide, 181 mm high, and 86 mm deep — a standard SENTRON 3VA2 frame footprint that fits existing DIN-rail or screw-mounted panel layouts. The breaker ships with an undervoltage release (UVR) and a complement of 2 auxiliary switches plus 1 trip alarm switch (HQ), so it covers remote status indication and undervoltage protection without separate add-on modules. Communication function is built in, enabling integration with higher-level monitoring or energy-management systems. The trip indicator provides local visual confirmation of a fault event.
Compliance and documentation
As a SENTRON-series MCCB, this part is designed to meet IEC 60947-2 and UL 489 standards for molded case circuit breakers. Compliance documentation — including RoHS, REACH, and manufacturer declarations — is available from Siemens upon request through the standard product-support channel.
